The recent interstellar asteroid Oumuamua is the inspiration for this question.
if a humanoid creature that had all the abilities to survive in space had hitched a ride on this asteroid and chose to jump off with enough power to reach earth at a high speed, what trajectory would the asteroid move in after the kick back force of the jump?
I want it to jump off with the asteroid in a similar position as the picture above (even though it was tumbling this suits the scene I want) but I want it to be at around 30 degree angle and the creature will be at the lower right end (see arrow) which would be facing earth, which could put the asteroid into a back spin when it jumps?
The asteroid will be between the point it was closest to earth and before it enters earths plane of orbit (yellow circle), preferably as close to earth as possible but not directly below earth because I want the view as it closes in to be of a well developed highly populated area of the world (haven't decided which yet but probably japan) and not a view of antartica and surrounding area.
so if a creature jumped off the asteroid with the conditions given how would this impact the trajectory of the asteroid, if any impact at all?
The creatures mass is that of an average human, I believe the asteroid was moving at around 49.67 km/s as it was under earth which was 41,317,365 km away. I may just use this figures and forget the scenic landing from another jump point, I am struggling with how fast the creature should get there as if it is fast that would make it ridiculously powerful and also will drastically affect what happens the asteroid.
