| Jan 28, 2013 at 15:12 | comment | added | eephyne | i just tested that and the same happen , the moon orbit around the sun without noticing the earth , it's orbit speed is faster (because of the mass I guess). For the moon to remain in the same distance from earth , i need the force to be almost null , no? | |
| Jan 28, 2013 at 9:05 | comment | added | John Rennie | The trouble is that for an object at the distance of the Moon the escape velocity from the earth is only 1.4 km/sec. So you need to get the Moon's velocity just right. I would start with the Earth and Moon at the same distance from the Sun, so the Moon is 384,400 km further round the orbit. At this point the velocity tangential to the orbit will be the same as the Earth, and the velocity radial to the orbit will be about the orbital velocity of 1.022 km/sec. | |
| Jan 28, 2013 at 8:51 | comment | added | eephyne | the problem is that with the velocity of moon+earth , the moon do not stick around earth, it doesn't behave like a satelite of earth. (i mean by that , that the path between the two is not the same and it's visible after a little time , i can post video to see if you like | |
