They appear to move on a great hollow sphere
The night time stars are suns, so distant they appear as points of light. Note that the planets Mercury, Venus, Mars, Jupiter, and Saturn can be seen without a telescope and can be mistaken for stars.
planets appear to move
Similarities: Stars and planets can appear the same - like pinpoints of light in the night sky. Differences: Planets are rock or gas, and do not glow by themselves but reflect the light of stars which illuminate them. Stars fuse hydrogen into helium and give off enormous amounts of energy, some in the visible range. Stars are MUCH bigger than planets.
planets are much closer to us than the stars
The reason you can see planets and stars at night is that their light is faint and the brightness of the sun obscures them during the day. At night, when the sun is not visible, the fainter light from the planets and stars can more readily be seen.
planets are much closer to us than the stars
Stars in the night sky appear fixed, since they are much further away than planets. The planets can be identified through their apparent brightness and their movement among the background stars over time.
Because the stars emit light. The closer they are, the brighter. Also planets reflect the light off of the stars, so they also look like stars.
because they're way closer than the stars
the stars and some of our planets
Stars give off light whereas planets reflect light.
Day and night, the planets constantly orbit the sun. This makes the planetary positions appear to change each night with respect to the background stars from the perspective of earth. So the positions do not change only at night, it is just at night we can see the positions have changed a little bit more.
