Why do planets move relative to the stars?

Answer 1

Gravitational pull. Have you heard of the "heliocentric theory"? This says that the sun is the center of our galaxy, the milky way. because of its mass, all the planets in this solar system orbit around it. our moon is in the earths pull and orbits it. the planets move with the earth. actually the stars do as well. ____________________ To clarify: You may hear people say things like "the fixed stars", or "against the back-drop of the fixed stars", or "the distant stars", or "the canopy of stars". These refer to the fact that the stars (not including planets and other objects) seem not to move relative to one another. This canopy of stars does appear to move relative to earth, because of our orbit and our axial rotation. But, for example, the stars of Orion always form the constellation of Orion, even though we may see it rise and set at different times, and it may not even be visible at night, depending on the time of year. On the other hand, the planets and many other objects are orbiting the sun, and they are not part of that huge display of very distant stars and galaxies. We can observe the orbital movement of the planets, and can easily see that their positions against the back-drop of stars change according to their positions in their orbits.

Answer 2

The planets appear to move because they are in orbit around the sun and because Earth moving as well. The planets are close enough to us for Earth's motion to make a noticeable difference in a planet's apparent position.

Answer 3

The planets revolve around the Sun because of its gravitational influence. The Sun and the rest of the Solar System, revolve and the centre of the Milky Way Galaxy for exactly the same reason.

Answer 4

Planets and stars are all moving in various ways, however, the stars are much more distant than the planets, and we cannot see their motion. Planets (such as our own planet, the Earth) orbit the sun, which we can observe.

Answer 5

Everything moves, even stars. Moons are within a planets gravity well. Planets are within a Stars gravity well. And stars all move around the centre of the Galaxy, which may be a super massive black hole. The reason it appears that the stars dont move is because they are so far away from us, and are moving in the same direction.

Answer 6

because the mass of gravity around the star pulls the planet in accordance to the star's position
