Q: Why can’t we see the lunar landers from the Apollo missions with the Hubble (or any other) telescope?
The lunar landers are each about 4 meters across and about 384,400,000 meters away, which makes them about as hard to see as a single coin from a thousand miles away. You and every telescope on Earth (and the Hubble Telescope in low Earth orbit) are all about a quarter million miles from the Moon and the landing sites thereon. Answer Gravy: It turns out that the best/biggest telescopes we use today on Earth are can’t detect things the size and distance of the lunar landers using visible light. The lunar landers are a little over 4 meters across (seen from above) and are about 384,403,000 meters away. In order to see this from Earth, we’d need a telescope that is, at absolute minimum, about 200 meters across.
