How do the planets farther from the Sun differ from the planets that are closer to the Sun?
The farther away from the sun, the farther apart the orbits of the planets become (the planets farther away from the sun are more spaced out). The average distance between Mercury and Venus, the two closest planets to the sun, is about 0.779 au. The average distance from Mars to Jupiter, the two planets in the middle, is about 5.32 as. The average distance from Uranus to Neptune, the two planets farthest from the sun, is about 33.2 au.
Why stars appear as points while planets appear as discs?
Stars are usually much farther away from us than planets, so they appear as points of light due to their vast distance. Planets are relatively close to Earth in comparison and have a visible circular shape since they reflect the light from the Sun, making them appear as discs in the night sky.
Why do the distant planets have a longer year than earth does?
For the same reason that it would take longer to run around your block than to run around your yard. The further planets have a further distance to travel to make one revolution around the sun.
How does the of the planets farther from the sun compare with the size of the planets closer to it?
The four outer planets are all significantly larger than the four inner planets. Beyond that there's no simple relationship. The size of the planets (from smallest, 1, to largest, 8) in order of distance from the Sun: 1, 3, 4, 2, 8, 7 ... and then it gets vague. If you go by radius, the last two are 6, 5 and if you go by mass they're 5, 6 (either way, they're nearly twins).
What celestial body controls the movement of the planets?
No celestial body controls the movement of the planets; gravity does. The sun serves as the center of Earth's solar system and provides the greatest gravitational force. This causes the other planets to revolve around the sun. Planets' distances from the sun affect their speed. For instance, Jupiter, which is about 5 times farther from the sun than the Earth is, takes far longer than a year to circle the sun not only because it is farther, but also because the distance weakens gravity and causes it to go slower because it is trying to move out of the Sun's pull.
How does the of the planet temperature vary with the distance from the Sun?
Roughly speaking, as you go farther away from the Sun, planets get colder.

Does the sun go farther away?
Not in any important timescale.
Why does it take longer for the planets farther from the sun to revolve around the sun?
Planets farther from the sun have larger orbits, which means they have to travel a greater distance to complete one revolution around the sun. This larger distance results in a longer orbital period compared to planets closer to the sun. It follows Kepler's third law of planetary motion, which states that the square of a planet's orbital period is proportional to the cube of its average distance from the sun.
Why do some planets take longer to revolve?
Because they are farther away from the sun, and the sun is what they revolve around, so they have a longer distance to go. That obviously makes the day longer on that planet, along with all other time measurements. Some planets take longer to revolve because of their distance to the sun. The further a planet is, the more distance it has to cover and the weaker the sun's gravitational pull is. Planets farther away from the sun move more slowly, and have more distance to cover.
Does the other planets go around the sun?
Our nine planets orbit around the Sun. Other planets that are light-years away orbit around their suns (A sun is just a large star with planets). Hope this helped!
Do planets travel at the same speed as they orbit the sun?
No. The the planets closest to the sun orbit the fastest. Mercury, the first planet from the sun orbits at about 107,000 mph. Earth orbits at about 65,000 mph, and Neptune, the farthest planet, orbits at about 12,000 mph.
How does the distance from the sun effect planets orbit?
In general, the planets that are farther from the Sun move slower, and take longer to go around the Sun. The quantitative relationship (i.e., exactly how much slower) is expressed by Kepler's Third Law.
Why do the planets further the sun have longer years?
The farther a planet is from the sun, the farther it has to go on its way around.Also . . . the way gravity works, a planet farther from the sun will move slower in its orbit.So when you add it up . . . moving slower plus a longer way to go . . . the farther ones take longer for each revolution.
How far is the planets away sun and how manymoons do they have and the diameter?

Does the distance of the planet from the sun affects its period of revolution?
Yes, the distance of a planet from the sun affects its period of revolution. According to Kepler's third law of planetary motion, planets that are closer to the sun have shorter revolution periods compared to planets that are farther away.
Why stars appear as points while planets appear as discs?
Stars are usually much farther away from us than planets, so they appear as points of light due to their vast distance. Planets are relatively close to Earth in comparison and have a visible circular shape since they reflect the light from the Sun, making them appear as discs in the night sky.
