Kepler's 3rd Law: P2 = a. Kepler's 3rd law is a mathematical formula. It means that if you know the period of a planet's orbit (P = how long it takes the planet to go around the Sun), then you can determine that planet's distance from the Sun (a = the semimajor axis of the planet's orbit).
as we go outwards speed reduces for planets. Venus have highest among the three...
