In how much detail could the Hubble Space telescope see the moon surface?
Although the distance between New York and San Francisco (roughly 4000 km) is nothing compared to the astronomical distances, Hubble is a powerful instrument that can distinguish between two baseballs separated by one meter while seated in New York. The Moon is located 370,000 km from Earth (and from Hubble), so the telescope can see objects with a separation greater than approximately 100 m. Two objects closer than 100 m are indistinguishable for Hubble, which is why we cannot see the flag, the Apollo missions' landing site, etc.

Details as small as roughly 330 feet (100 meters) across can be seen on the Moon's surface by the Hubble Space Telescope.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.

- When we look at a picture of a galaxy, how is it possible that we see a disk form or a near perfect circle? Considering how long light takes to travel between the galaxy and the earth, shouldn't the images be more distorted?
