Can you describe to me our solar system?

We Answered:

The most common unit of measurement in the Solar System is the Astronomical Unit, or A.U. This is the avg. distance from the Earth to the Sun, about 93,000,000 miles. So, Earth is 1 AU. Mercury is about .3 AU, Venus - .7 AU, Mars - 1.4 AU (?), Jupiter - 5.4 AU, Saturn - 9.8 AU, Uranus - 19 AU, and Neptune - 30 AU. Pluto, now a dwarf planet is about 40 AU. There are 63,000 AU's in 1 light year. That should give you some idea of how small the Solar System really is. Consider the fact that the closest star to us is roughly 4 light years away. In AU's that's 63,000*4 = 252,000 AUs!! And that's close-by in cosmic terms.

You wind up the little key on the bottom...

The planets, most of the satellites of the planets and the asteroids revolve around the Sun in the same direction, in nearly circular orbits. When looking down from above the Sun's north pole, the planets orbit in a counter-clockwise direction. The planets orbit the Sun in or near the same plane, called the ecliptic.
