Each planet has a different time phase.
The outer planets take much more time and also travel longer to complete a whole orbit around the Sun, than the inner ones.
The planets have been around much longer than people.
The rotational period of the inner planets is much faster than the rotational period of the outer planets. The rotation of some planets takes years to complete.
The gas planets are much more massive than the terrestrial planets and therefore have stronger gravity. It is believed that as they formed many of their moons formed around them much like the planets formed around the sun. Other moons are likely captured asteroids and comets.
The moon orbits the planet Earth rather than the sun, so it is considered a moon.
It is called the solar system, and includes the Sun, planets, dwarf planets, asteroids, and comets. It extends much farther than the farthest planets, but not as far as the other nearby stars.
The four inner, rocky planets are also known as the terrestrial planets. These are; Mercury, Venus, Earth and Mars. Although much smaller and not as massive as the outer gas giant planets, they are more dense.
nobody knows for sure because our unerverse is so big
The outer planets revolve about the same speed they just have to travel a much longer distance so it takes longer.
Generally, a satellite is a small object in a stable orbit around a much larger one. > Examples: Communication satellites around the earth. Planets around the sun.
Stars are not planets. They are like our sun and may or may not have planets orbiting around them. Stars are hot and the heat makes them look like bright lights in the sky on a clear night. Planets do not create very much, if any, visible light and are much harder to see because they only reflect the light from stars.
