An astronaut crash lands on an elongated asteroid with extremely strong gravity. He manages to crawl away from his ship and finds that the gravity in the middle is normal and the gravity at the far end is reversed. Time is also affected by gravity and goes backward at the far end of the asteroid. His dog was injured and he carries it to the far end to heal it. He then goes back to his ship, manages to fix it, and goes back home. There were trees in the middle with fruit as well. I think that’s all I remember. The problem I’ve been having is if I put ‘gravity’ and ‘movie’ in the same search I get Gravity with Sandra Bullock which definitely isn’t the right movie. Thanks in advance for any help.
