SpaceLover, the most important point isn't that the distance varies (which you seem to get), but that the Earth-Moon distance is

*tiny* compared to the Earth-Mars distance, so the Moon-Mars distance is essentially the same as the Earth-Mars distance.

Let's say I asked you what the distance was from San Francisco to Times Square. The answer is about 2578 miles. Now I ask you what's the distance from San Francisco to 50th and Broadway, which is a couple of blocks from Times Square. The answer is still 2578 miles because a couple of blocks is negligible compared to 2578 miles.

As people have said in this thread, the Earth-Mars distance varies from 36 million miles to 250 million miles. To get the range of Moon-Mars distances, you'd need to add/subtract the Earth-Moon distance which is about 200,000 miles, but that's nothing compared to, say, 250 million miles.

So for all intents and purposes, the Earth-Mars and Moon-Mars distances are the same, anywhere from 36 million miles to 250 million miles, more or less.

You can't possibly have any more questions now
