That's 39.5 AU. NASA Solar System Factsheets Jupiter is the largest of the planets, spanning nearly 1.75 millimeters in diameter on our football field scale. Mars is too cold. Our solar system is huge. That means that all the planets, moons, planetoids, asteroids, comets and dust make up only 0.14%! Jupiter's diameter is about equal to the thickness of a U.S quarter in our shrunken solar system. Kristen Erickson Asteroids roam far and wide in our solar system. (If you could lump together all the thousands of known asteroids in our solar system, their total mass wouldn't even equal 10 percent of Earth's moon.). On this scale, our little friend Voyager 1 has left the game and is well out in the stadium parking lot or beyond. It is 1.4 yards from the end zone. Change ), You are commenting using your Twitter account. The spacecraft is traveling away from the Sun at about 3.5 AU per year. Social Media Lead: One AU, about 93 million miles (150 million kilometers), represents the average distance from the Sun to the Earth. Our solar system's largest planet is an average distance of 484 million miles (778 million kilometers) from the Sun. The gas giant is about 38 yards from our end zone. It would take an airliner more than 20 years to fly that distance — and that's just a one-way ticket. Uranus is about the point where our cosmic coach would call in an interplanetary field goal kicker. So our Sun is about halfway through its life. Even Jupiter remains pretty close to our end zone on the 10.5-yard line. Director, NASA Planetary Science Division: videos, How the changing seasons affect hedgehogs, How the changing seasons affects apple trees. More importantly there are other lesser known, but similar sized, objects to Pluto orbiting the Sun that aren’t shown in this picture – including Eris, and Ceres. Scientists figured out a while ago that writing out those huge numbers wasn't the best use of their time, so they invented the Astronomical Unit (AU). It also is fairly small in comparison with other big stars. Read about our approach to external linking.
Amanda Barnett Stars like our Sun burn for about nine or 10 billion years. KS1 But as you can see here, the re-classified ‘dwarf planet’ is smaller than most of the major moons of the Solar System. The Sun. The Sun is around 1,391,684km in diameter, and weighs in at a hefty 1,988,500,000,000,000,000,000,000,000,000kg. The ringed world is about 887 million miles (1.4 billion kilometers) from the Sun, or 9.5 AU.
Approximate diameter of the real sun. On this scale, the Sun, by far the largest thing in our solar system, is only a ball about two-thirds of an inch (17 millimeters) in diameter sitting on the goal line — that's about the width of a U.S. dime coin. Our star isn’t just the biggest thing in our solar system, it actually contains an amazing 99.86% of all the mass in the Solar system. The true average distance from the Sun to Venus is about 67 million miles (108 million kilometers) or 0.7 AU. Neptune is where things start to get way out. NASA Official: It is slightly larger than Venus at about 0.16 millimeters. On this scale, Mars is about 0.08 millimeters. That's quite a kick. The chromosphere, the next layer of the sun's … This site is maintained by the Planetary Science Communications team at, Make a solar system in your own neighborhood. That leaves us on planet Earth with just about 0.2% of the mass outside the Sun to play with, or a tiny 0.0003% of the total mass of the Solar System.

In an effort to bring these vast distances down to Earth, we've shrunk the solar system to the size of an American football field. In fact, our sun is classified as a G2 dwarf star. In real distances that's an average of roughly 186 million to 372 million miles (300 million to 600 million kilometers ) from the Sun, or 2 to 4 AU. It still has about 5,000,000,000—five billion—years to go. It's about 79 yards out from the Sun or 3.7 billion miles (5.9 billion kilometers) on average in real distances. In real distances, that's an average of 1.8 billion miles (2.9 billion kilometers) — 19 AU — from the Sun. On to Earth, sitting pretty on the 2-yard line. This clip could help to prompt discussions about why the Sun appears to be so small compared with its actual size. That's 5.2 AU. Venus is too hot. To get the full effect and see the planets and major moons compared to the full size of the Sun, click on the image to the right (which is just an extract, with the sun trimmed to fit into this post). But there’s even less once you take the two next biggest objects in the solar system, Jupiter and Saturn – which together represent more than 88% of what’s left…. Neptune, a little smaller than Uranus, is 0.6 millimeters on this scale. Our sun is one of billions in the entire universe. Phillips Davis Surprising don’t you think? Saturn is on the field at 19 yards from the goal line.
