1) majority of the 'dust' in the solar system has already been accreted millions, if not billions, of years ago by the planets and sun. There isn't a heck of a lot of loose matter left out there 2) Any planet with an atmosphere will burn up any non-gaseous matter 3) technically speaking, the other large bodies without atmosphere ARE still growing. But you'd probably have to wait hundreds of millions of year for that growth to even happen. Generally speaking EVEN though Earth does capture those space 'dust' things (about 40,000 metric tons of it each year),it's still to little to be noticed.

Earth is basically from matter, all the matter around the Universe came together to form Earth, the only way for Earth to grow much bigger is if there was an unlimited supply of matter, there isn't and therefore Earth cannot get much bigger than it is now.

Explain the main reason why the position of the moon in the sky changes over the course of a single night. In other words why is

Afina-wow [57]

Explanation: The moon changes its visual position relative to the earth during one night because the earth revolves around its axis. As the earth revolves around its axis it means that within a few hours an observer at a certain point on earth will, due to the earth's rotation, change the angle at which he sees the moon.

The fact that the moon also moves, that is, rotates around the earth, and that it takes about a month for a full rotation around the earth, is why we will see the moon in a different position in the sky at the same time next night.
