Gravity from the Sun reaches throughout the solar system and beyond, keeping the planets in their orbits. Gravity from Earth keeps the Moon and human-made satellites in orbit. It is possible to far away from a planet or star and feel less gravity, because gravity decreases with distance.But that doesn't account for the weightless feeling that astronauts experience in space.ravity from the Sun reaches throughout the solar system and beyond, keeping the planets in their orbits.

The Moon orbits the barycenter of the Earth-Moon system, the common center of gravity of these two objects. It takes 27.32 days to do this. The barycenter is 3000 miles from the center of the Earth, so it lies 1000 miles underground. The barycenter orbits the Sun in 365.2453 days.he moon orbits the earth. The earth orbits the sun. Anything that orbits the earth will go around the sun in the same amount of time it takes the earth to go around the sun: one year plus a few spare hours. 62,040,610 Idiots Â· 8 years ago.
