Hi All,
I know that Rosetta was orbiting around 67P/Churyumov–Gerasimenko. This asteroid has extremely low gravitational force acting on Rosetta. I believe that if the celestial body is heavy (mass), then there would be greater gravitational pull on the satellite and the orbital speed of it's satellite should be fast near it's surface so as to avoid collision.
I have below questions.
1. Since there is almost zero gravitational pull on Rosetta by 67P/Churyumov–Gerasimenko, does the Rosetta orbit the comet very slowly ?
2. The comet itself rotates. In order to make observations of the comet (Geo-stationery orbit), the orbital speed of Rosetta should match with the rotational speed of comet. Now assume if rotational speed of comet is very fast. Now in this case, Rosetta should match that speed so that it will be stationery to the comet. But at that speed it will fly away from comet. So, what maneuvers they put in place to achieve this ?
Thanks...
