On average that is. Mercury is actually the closest planet to every other planet in average. Because when it’s on the other side of the Sun, it’s still pretty close.
The average distance from Earth to Mercury is about 1.04 astronomical units (au), which is the average distance between Earth and the Sun.
In comparison, the average distance between Earth and Venus is approximately 1.14 au, while the average distance between Earth and Mars is around 1.7 au.
You’re still right, though - talking about closest planet on average isn’t very useful, because it’s always going to be the closest planet to the sun. Asking “what planet can get closest to some [Planet]” is more interesting and enlightening.
The closest planet to Earth is Mercury.

Wow, you’re absolutely correct!
The average distance from Earth to Mercury is about 1.04 astronomical units (au), which is the average distance between Earth and the Sun.
In comparison, the average distance between Earth and Venus is approximately 1.14 au, while the average distance between Earth and Mars is around 1.7 au.
You can check that in Wolfram Alpha.
I learned this from QI recently. Great piece of trivia!
