Math
the time x (in days), that it takes a planet to revolve around the sun can be approximated by the equation x=0.407√(d^3),where d is the mean distance of the planet from the sun in millions of miles. It takes Venus approximately 226 days to complete one revolution of the ...

The earth doesn't "float", it orbits the sun following Newton's Law of Universal Gravitation. The presence of the sun, which is much more massive than earth and the other planets, drives the movement of the planets. The sun is so dense that a spoonful of it is approximately as...
