how do the planets in our solar system orbit the sun?

We Answered:

You ever seen a bowling ball sitting on a trampoline? Where it makes the indention at its heaviest point? Do that sometime and then roll a marble around it and watch what happens.

The Sun works somewhat like that bowling ball would, with the trampoline surface representing the fabric of space (not 3 dimentional of course). Granted that marble would roll towards the bowling ball on Earth eventually because of gravity, space is a vacuum and nothing would "pull" the planet down. So it continues to move at the constant speed that keeps it in orbit. Since the Sun exerts a massive amount of gravity, and since the planets have a sideways motion, they continue orbiting accordingly.

The _only_ change in the last 140 years has been the discovery of Pluto in 1930, and its declassification as a planet in 2006
