It’s so big that 1.3 million Earths would fit inside a hollowed-out Sun. The mass of the sun is 1.989 x 1030 kilograms, about 333,000 times the mass of the Earth. Display the NASA illustration: How Big is the Sun? But the sun's weight isn't constant. However, it is also theorized that by that time, no life form, even human life is still existent on earth due to what is called the Second Big Bang. The Sun is about 800,000 miles (1.3 million kilometers) in diameter. The distance from Earth to the sun is called an astronomical unit, or AU, which is used to measure distances throughout the solar system. Hence, there have to be 109 “Sun”-pixels for each “Earth”-pixel, which is manageable. That's 1 AU. Its equatorial diameter and its polar diameter differ by only 6.2 miles (10 km). “Based on our simple model, we say that nearly all stars form with a companion.”, Additional reporting by Nola Taylor Redd, Space.com contributor. Over time, the solar wind has carried particles, and thus mass, away from the star. The sun has just consumed about half of its life and it is theorized that as it gets older it will become bigger and eat up the inner planets including the Earth. a half-degree angle (there are 360 degrees in a circle). The Sun is also to scale with the rest of the planets. All the energy we have comes, or once came from, the Sun. Answer: Time = 4,500,000,000 km / 28,000 km/h = 160714 hours or 6696 days or . It’s really far away, too – about 150 million kilometers (93 million miles) Even at that distance the Sun affects everything on Earth. Move the Sun 93 times closer and it’ll appear 93 times larger. These elements will collect in the center of the sun. The red planet is about 228,000,000 km (142,000,000 miles) on average from the Sun. That's 1 AU. The sun’s total surface area is 6.1 x 1018 square meters. Compared to the Earth the Sun is HUGE. this site is the is the best! These are the comets. For example, on Earth, the apparent diameter of the full Moon is substantially equal to that of the Sun, i.e. By far, Jupiter is the largest planet with Saturn the second largest, but they are certainly no where close to being as big as the Sun, which has a radius of 432,000 miles (695,000 km). That will make 109 earths side by side to match sun’s diameter. Making it simple, imagine that it is 333 000 times the mass of the earth. Although it is huge enough in consideration to other solar objects, it is not that big when compared to other stars. In the table below, use proportional math to fill in the travel times from the sun … "Similarly, with the Mercury and Venus transits, it turns out [a measurement based on those is] not quite as precise as you'd like it to be.". The image is captured in the 304 Angstrom wavelength, which is typically colorized in red and shows temperatures in the 50,000 Kelvin range. Join our Space Forums to keep talking space on the latest missions, night sky and more! This is almost 10 times larger than the planet Jupiter and about 109 times as big as the Earth. The total volume of the sun is 1.4 x 1027 cubic meters which will make 1.3 million earths to fit inside. On this scale, Mars is about 0.08 millimeters. New York, In about 5 billion years, scientists think the sun will start to use up all of the hydrogen at its center. The mass of the sun is 1.9891 x 1030 kg. At this time in the Sun's life, they account for 74.9% and 23.8% of the mass of the Sun in the photosphere, respectively. Meanwhile, in the heart of the star, mass is converted into energy. Remember that our sun is a dwarf star. More the Sun is far of a planet and more its size will appear small and vice versa more it is close and more it is great. 695,700 kilometres (432,300 miles) is approximately 10 times the average radius of Jupiter, about 109 times the radius of the Earth, and 1/215th of an astronomical unit, the distance of the Earth from the Sun. Earth orbits the sun 100,000 times closer than the Oort Cloud, at an average of 92,955,807 miles (149,597,870 km).The distance from Earth to the sun is … How Large Is the Sun? How far is the Sun from the middle of our galaxy, the Milky Way ? The Earth-Moon distance is not shown to … Truly those stars are enormous," NASA says on its SpacePlace website. What is about this big in our universe (ie if the sun were a beach ball, the Milky Way would be the size of …)? In other words, you could line up 109 Earths across the face of the Sun. The Sun has a diameter of 1,392,000 km (865,000 miles) while the Earth’s diameter is only 12,742 km (7,918 miles). It is big enough to consume all the planets inside it. The sun is classified as a G-type main-sequence star, or G dwarf star, or more imprecisely, a yellow dwarf. I believe it is not fun because something is on that way ! In fact, the diameter of the sun is a whopping 1.391 million km. The Sun's diameter of 1,392,000 km is 109 times the Earth's equatorial diameter of 12,756 km. The distance separating the Earth and the Sun (the orbital radius of the Earth around the Sun), r, is 1.5 × 10 8 km; The Earth's velocity around the Sun is just the total distance travelled divided by the time required for the Earth to make one complete orbit around the Sun, T You will receive a verification email shortly. How big (in scaled km) is the Milky Way in this scale? Applying our scale factor this equates to a diameter of 7.3 m in our model. Betelguese, Antares and Aldebaran are well known red giant stars. The Sun has a very big magnetic field. Get breaking space news and the latest updates on rocket launches, skywatching events and more! i am using this report for a project, I wish these facts were written better, some of the wording appears to be from someone with English as a second language, and the ‘facts’ take some effort to decipher. This dataset has the Sun as the background and then has a picture of the solar system drawn to scale. Actual diameter: 143,000 km (90,000 miles) Actual distance from the Sun: 778,300,000 km (484,000,000 miles) Mars 14 Yards from Earth Actual diameter: 7,000 km (4,000 miles) Actual distance from the Sun: 227,900,000 km (142,000,000 miles) Moon 2 Inches from Earth Actual diameter: 3,5000 km (2,000 miles) Actual distance from the Earth: 384,000 km The sun's helium will get hot enough to burn into carbon, and the carbon will combine with the helium to form oxygen. A general fact about the stars is that they get bigger as they get older. Again, let’s put this number into perspective. Stars generally get bigger as they grow older. There was a problem. The diameter of the Sun is thus 109 times as great as the Earth's diameter. (This is more than three times the distance from the Earth to the moon!) NY 10036. Even Jupiter, the biggest solar planet with a diameter of 142 600 kilometers wide will is still small to match that of the sun. C is the diameter of image (mm). The sun contains 99.8 percent of the mass of the entire solar system, leading astronomers Imke de Pater and Jack J. Lissauer, authors of the textbook "Planetary Sciences," to refer to the solar system as "the sun plus some debris. © However, in comparison to other stars, it is just small. Space is part of Future US Inc, an international media group and leading digital publisher. The sun is quite a bit bigger than the Earth. Thank you for signing up to Space. According to ”Bad Astronomer” Phil Plait, the sun loses an average 1.5 million tons of material every second to the solar wind. Please deactivate your ad blocker in order to see our subscription offer. A is the diameter of the sun (km). The Sun is almost a perfect sphere. With the following figures in consideration, that will make the sun a very huge heavenly object. to give students a sense of the relative sizes of planets compared to an everyday object like a basketball. Earth orbits the sun at an average of 149.6 million km (93 million miles). The Sun’s core is extremely hot! It’s bigger than huge. This image from the Solar Dynamics Observatory (SDO) shows the sun at 12:45 PM EDT on July 12, 2012 during an X1.4 class flare. It's possible that the sun is even larger than previously thought. Our Sun is a bright, hot ball of hydrogen and helium at the center of our solar system. The red giant has more than 5 solar radii. The Sun is composed primarily of the chemical elements hydrogen and helium. It is 864,000 miles (1,392,000 km) in diameter, which makes it 109 times wider than Earth. "For most people, yes, it doesn't really matter; it won't change everything," Jubier said. Solving for A is simply a matter of multiplying B and C and dividing that product by D. The sun is definitely huge compared to other objects in the solar system. The sun will puff up into a red giant and expand past the orbit of the inner planets, including Earth. Calculate the scaled planet diameters and planet-sun distances for a solar system model. You could line up 109 Earths across the face of the sun. So we will take the average distance between the Sun and Pluto as the radius of the Solar System (which is 5,913,520,000 km, or 39.5 AU, where AU stands for Astronomical Unit) 2 - Orbit of comets Beyond the orbit of Pluto, there are object that orbit the Sun.

In terms of weight, the Sun is 333,000 times heavier than the Earth and accounts for 98% of all mass in the solar system. Our Galaxy, the Milky Way. :))))))))))))))))))))))), i love this site! Red Giant stars swell up to 500 times the diameter of the Sun. It even makes up 99% of the entire mass of the solar system. But when he matched actual photos and historical observations with the models, he found precise eclipse shapes only made sense if he scaled up the sun's radius by a few hundred kilometers. 30 000 light years. That's 1.5 AU. or 9088 km (Proxima Centauri) 25 trillion miles = (roughly from Baltimore to Hawaii!) The Sun is ~93 million miles away and apparent size is proportional to distance. … It makes 11 900 Earths. According to NASA's solar scientist C. Alex Young, if the sun were hollow, it would take about one million Earths to fill it. “The idea that many stars form with a companion has been suggested before, but the question is: how many?” the study's first author Sarah Sadavoy, a NASA Hubble fellow at the Smithsonian Astrophysical Observatory, said in a statement. Do you think it will be crowded? The sun's circumference is about 2,713,406 miles (4,366,813 km). Its equatorial diameter and its polar diameter differ by only 6.2 miles (10 km).

At a scale of 1 to 10 billion, the Sun would be about the size of a grapefruit. About 1.3 million Earths could fit inside the sun. Real diameter of galaxy = $10^5 ly =10^5*9.46*10^{12} =9.46*10^{17} km$ Scalled diameter of galaxy (km) = $2.83*10^8 km$ As noted earlier, Earth's average distance to the Sun is about 93 million miles (150 million kilometers) from the Sun. Transcribed Image Text The earth is about 12,760 km m diameter and shout 150 million kilometers away from the sun The nearest stars besides the Sun are about 4.3 light-years away (1 light-year = 9.5 Times 10^12 km). How many whole Earths could fie the diameter of the Sun? Visit our corporate site. Following are some other fun and interesting facts about the Sun. Some stars such as the Betelguese is older than the sun and it is 500 000 000 kilometers wide making it 500 times bigger than the sun. Next nearest star 4.3 light years = 5680 miles(!) The sun’s diameter is 1.4 million kilometers while its circumference is around 4.4 million kilometers. D is the distance between the image and the pinhole that produced it (mm). Use 100,000 ly for the actual width of the Milky Way. Examples: Scale 1 : 100000000 or Sun Diameter = 10 cm or Neptune Distance from Sun = 1000 ft. The average diameter of Jupiter is 139,822 kilometers. The radius of the Earth is 6378 km and the radius of the Sun is 6.955 x 103 km. It varies slightly from pole to equator due to its rotation, which induces an oblateness in the order of 10 parts per million. 18.3 years. Later, the sun will shed its outer layers, forming a planetary nebula and leaving behind a dead core of mostly carbon and oxygen — a very dense and hot white dwarf star, about the size of the Earth. The sun’s diameter is 1.4 million kilometers while its circumference is around 4.4 million kilometers. That could be a problem if you are planning to skirt the edges of the next solar eclipse. The diagram to the right shows just how big the sun … The sun's companion may have been a wide binary, putting it as much as 17 times farther from the sun than Neptune and making it easier to be stripped away. Interesting, right? The diameter of the Sun is 1.391 million kilometers or 870,000 miles. "But the closer you get to the edge of the [eclipse] path, the more risk you take.". The sun is the largest and the most massive object in the solar system, but it is just a medium-sized star among the hundreds of billions of stars in the Milky Way galaxy. While that sounds like a lot, it's only about 0.05 percent of the star's total mass. Problem 3 – The fastest unmanned spacecraft, Helios-2, traveled at a speed of 253,000 km/hr. Most stars have a companion, with some part of a triple or even a quadruple system. An unthinkable 13,600,000 degrees Celcius! Mars is on the three-yard line of our imaginary football field. However, since the distance to the Sun is 149597900 km, the distance between the Earth and the Sun to the same scale would be 11741 “Earth”-pixels. "We have found stars that are 100 times bigger in diameter than our sun. New research suggests that all stars may have started out with a companion. Actually, the sun — like other G-type stars — is white, but appears yellow through Earth's atmosphere. In fact, at some time,s it is closer to the Sun than Neptune! The mean radius of the sun is 432,450 miles (696,000 kilometers… No, there will still be enough space to accommodate several times the other planets too. The Sun has a diameter of about 1,392,000 km (~865,000 miles). Even Jupiter, the biggest solar planet with a diameter of 142 600 kilometers wide will is still small to match that of the sun. This artist’s illustration compares the sizes of the sun and a red giant star. The total volume of the sun is 1.4 x 1027cubic meters. It is the closest thing to a sphere found in nature with only a 6.2 mile (10 kilometres) difference between its vertical and horizontal measurements. While the sun is typical in most respects, it does have one quality that stands out from the majority of stars — it is a loner. B is the distance between sun and earth (149,600,000 km). Xavier Jubier, an engineer and solar eclipse researcher, creates detailed models of solar and lunar eclipses to determine precisely where the moon's shadow would fall during the solar eclipse. It may be the biggest thing in this neighborhood, but the sun is just average compared to other stars. The volume of the Sun is 1,299,400 times bigger than the volume of the Earth; about 1,300,000 Earths could fit inside the Sun The sun is nearly a perfect sphere. Please refresh the page and try again. It is 143.73 billion km from the Sun, thus giving the Solar System a diameter of 287.46 billion km. As noted earlier, Earth's average distance to the Sun is about 150,000,000 km (93,000,000 miles) from the Sun. The Sun is huge. Even missions like NASA's Solar Dynamics Observatory (SDO) and measurements of the inner planets across the face of the sun don't refine the star's radius as precisely as desired. Mars is on the three-yard line of our imaginary football field. Example; “Even Jupiter, the biggest solar planet with a diameter of 142 600 kilometers wide will is still small to match that of the sun.”, The sun is huge guys,we can count up to 500 times the earth size.my God is great. The sunis nearly a perfect sphere. Altogether, Plait estimated that the sun has lost a total of 1024tons of material over its 4.5-billion-year lifetime, or more than 100 times the mass of the Earth. How big is the Milky Way ? The mean radius of the sun is 432,450 miles (696,000 kilometers), which makes its diameter about 864,938 miles (1.392 million km). i love this web site also who ever made this is smart, this is a really really good website!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! How much bigger is the sun than Jupiter? The distance to the Earth from the sun at 149,000,000 km = 1 AU is 107 times the diameter of the Sun and 388 times the Earth-Moon distance. The Size of the Sun The Sun's diameter is 864,938 miles (1,391,980 km). Wright said different papers using a variety of methods have produced results that differ by as much as 930 miles (1,500 km). "We have also seen stars that are just a tenth the size of our sun.". 42 trillion km ----- Note: 1 AU = "astronomical unit" is defined to be the mean distance from the earth to the sun. The diameter of the Sun is 1391000 km. The world is become the dust. But it may not have always been a solo star.
