I couldn’t find any source for that, but exosphere is considered to extend to 10,000km or 190,000km, from which the latter is about halfway to the moon.
Anyways those numbers are pretty damn tiny even on a small solar system scale
Anyways, even if you look from very close, from our own moon to the earth, anything on the low earth orbit is so extremely close to the planet. Just look at some of the famous earthrise photos, and think of something orbiting ~8% of the radius distance
My favorite fact is that earth’s atmosphere extends 95,000 miles / 150,000 km beyond the moon.
