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 sun has more than 99.8% of its total mass The sun is a big star. Jupiter remains pretty close to our end zone on the 10.5-yard line. Kristen Erickson Our solar system is huge. ( Log Out /  How much bigger than Earth is the Sun? The chromosphere, the next layer of the sun's … Mars is too cold. Bill Dunford.

Read about our approach to external linking. I included Pluto in this graphic because it is a familiar object, which was one of the reasons many people were upset when it was demoted from ‘planet’ status in 2006. One AU, about 93 million miles (150 million kilometers), represents the average distance from the Sun to the Earth. ( Log Out /  On our football field, you'd find them scattered like so many slow-moving linebackers between the four and eight yard lines. That's 39.5 AU. Venus is too hot. When those five billion years are up, the Sun will become a red giant. Looking at the stats didn’t give me a proper feel for just HOW MUCH bigger the Sun is than the Earth! The true average distance from the Sun to Venus is about 67 million miles (108 million kilometers) or 0.7 AU. On to Earth, sitting pretty on the 2-yard line. 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. Our Sun is an average sized star: there are smaller stars and larger stars, even up to 100 times larger.

Make models of the planets (to scale if possible) and compare the size of the Sun and Earth with other planets. The gas giant is about 38 yards from our end zone.

Phillips Davis Just as most quarterbacks would be extremely pleased to find their team within two yards of a touchdown, Earth reaps many benefits from this prime location in the solar system. Stars like our Sun burn for about nine or 10 billion years. That's 1 AU. Change ), You are commenting using your Twitter account. Scientists sometimes call our region of space the "Goldilocks Zone" because it appears to be just right for life. Our sun is one of billions in the entire universe. In reality, the average distance from the Sun to Mercury is roughly 35 million miles (58 million kilometers) or 0.4 AU.

Neptune, a little smaller than Uranus, is 0.6 millimeters on this scale.

Many other solar systems have multiple suns, while ours just has one. The size of the sun in comparison. This clip could help to prompt discussions about why the Sun appears to be so small compared with its actual size. Our Sun is 864,000 miles in diameter and 10,000 degrees Fahrenheit on the surface. It is slightly larger than Venus at about 0.16 millimeters. It still has about 5,000,000,000—five billion—years to go. 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). Site Manager:

Sirius, the brightest star in the night sky, is twice as massive as the sun and 25 times more luminous. Even Jupiter remains pretty close to our end zone on the 10.5-yard line.

As noted earlier, Earth's average distance to the Sun is about 93 million miles (150 million kilometers) from the Sun. At the center of big sunspots the temperature can be as low as 7,300 degrees F (4,000 degrees C). Change ), You are commenting using your Google account. Asteroids roam far and wide in our solar system. Social Media Lead: 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.

Here’s a very brief run through….

So our Sun is about halfway through its life. It also is fairly small in comparison with other big stars.

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. Can this theory be shown using classroom equipment? Our solar system's largest planet is an average distance of 484 million miles (778 million kilometers) from the Sun.
