However, it's important to note that this is just an average. The actual distance between the two planets varies greatly depending on their positions in their orbits around the sun.

* At their closest: Earth and Mars can be as close as 54.6 million kilometers (34 million miles).

* At their furthest: They can be as far apart as 401 million kilometers (249 million miles).

Therefore, the actual distance between Earth and Mars at any given time can vary significantly.
