an astronaut on the Moon could experience zero gravity, and would see stars and Earth.
Since Moon's gravity is 0.167 times the gravity of Earth, astronaut would weigh very less. He would not be able to walk and would be to able to jump to large distance. Also, due to lack of atmosphere, the sky would appear black and stars would be visible all the time. The Earth would also have phases as viewed from the Moon.
Emotionally, it would be my best moment i'll just forget about countries on the Earth & think like a citizen (Human) on Earth
Hope this helps!
