Gram-negative ((of bacteria) being of or relating to a bacterium that does not retain the violet stain used in Gram's method). Hyponyms (each of the following is a kind of bacteria): acidophil; acidophile (an organism that thrives in a relatively acid environment).
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.

This alone should be enough to prevent our satellite from ever leaving orbit around Earth completely without intervention from some outside force. Another factor to consider is that the Moonâs satelliteâs tidal pull slows down Earthâs rotation by 2 milliseconds per century. Given enough time, will eventually slow it so that Earth takes a month to rotate (however long a month may be by that time). At this point, Earth will be fixed with one side facing towards the Moon, just as the Moon is already fixed with one side facing towards Earth.
