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.
What else can I help you with?
Why do planets appear to move through the background of stars?
Planets appear to move through the background of stars because they orbit the Sun at different speeds. As the Earth and other planets move in their orbits, their positions relative to the background stars change, causing them to appear to move across the sky. This is known as planetary motion.
Do planets always move east against the stars?
All the planets do orbit the sun in the same direction. However, as we orbit the sun quicker than the planets further out from us, and slower than the ones inside us they do at times appear to be moving the other direction.
Why do the positions of the planets change in relation to the background of stars?
The positions of the planets change in relation to the background stars due to their orbits around the Sun. As the planets move along their orbit at different speeds, their position relative to the background stars appears to change from our perspective on Earth. This phenomenon is known as planetary motion and is a result of the planets' orbital dynamics.
Which instrument do you use to see stars and planets?
A spectrometer is used to determine the composition of stars, and how fast they are going relative to Earth.
Why do stars wobble?
Stars wobble due to the gravitational influence of the planets orbiting them. As planets orbit their stars, their gravitational pull causes the stars to move slightly in response. Scientists can detect this wobble in a star's position, which provides information about the planets orbiting it.
How did the ancients distinguish between planets and stars in the night sky?
Ancients distinguished between planets and stars in the night sky by observing that planets move relative to the fixed background of stars, while stars maintain their positions.
Why do planets appear to move through the background of stars?
Planets appear to move through the background of stars because they orbit the Sun at different speeds. As the Earth and other planets move in their orbits, their positions relative to the background stars change, causing them to appear to move across the sky. This is known as planetary motion.
How are planets distinguished from stars on the celestial?
planets appear to move
Do constellations orbit planets and if they do what ones?
Constellations do not orbit planets. Constellations are apparent groupings of stars as seen from Earth, and they are fixed in their position relative to each other. They appear to move across the sky due to the Earth's rotation.

What moves faster planets or stars?
Relative to the Earth, almost all stars are moving faster than any planet is.

Why is it easier to see the planets motion and not the stars?
stars DONT move. if they did our SUN would move. IT DOESNT DOES IT??? no. the planets move. sometimes it seems like the sun moves but its the earth orbiting the sun. THE SUN IS A STAR! so its possible that somewhere in the NEVER-ENDING space, there could be OTHER planets orbiting another SUN. and on one of those PLANETS there could be LIFE. so earth could possibly be only one of the MANY planets with LIFE. ........possibly........ Distance. Stars are too far away for you to see them move. They are all orbiting around the galactic core but what you see is the light they gave off years ago (eg--a star 1,000 light years away, the light will get here 1,000 years later). Download a good star chart and move the time line back or forward then you will see the stars move.
Why do planets move across the night sky but stars don't?
The planets are closer. (They all move - and differently.)
Why do planets wander?
The ancient Greeks called planets 'wanderers' because they appear to move through ther skies in relation to the 'fixed' stars. The apparent movement is because the planets are much closer to the Earth than the stars, and all planets rotate around the Sun, thus all move in relation to each other.
