I see what you did here^^
For OP : careful about those relative calculus. In the same way, do you which planet is the nearest to Earth ?
Venus ?
Nope. It's Mercury.
Indeed, Venus' orbit is the closest to Earth's orbit. But when Earth is at a point of its orbit, and Venus diagonally opposed (which means the Sun is between them), the distance between the two planets is : (Earth to Sun) + (Sun to Venus). Which is significantly higher than (Earth to Sun) + (Sun to Mercury).
So if you integrate during a very long time the distance between every planets, and make an average, you will demonstrate that Mercury is the closest planet to every other planet in the Solar System !
