I wonder if it could be seen from earth by telescope.
- adrianN 8y agoThe Keck Telescope has a 10m mirror, so it can resolve roughly 1.2 * 400n / 10 radians (at 400nm wavelength)[1]. The distance to the Moon is about 384000km. If you plug things into Wolfram Alpha [2], you get about 18m for the smallest object on the Moon that can be resolved by the Keck Telescope. I suppose that there are more technical problems that further limit the resolution. It seems unlikely that you'll be able to see anything using a telescope.
