Gravity. The closer a planet is to the sun, the faster it must move to keep from falling into the sun.
So note; the closer in; the smaller the orbit AND the faster the speed.
The outer planets take longer to orbit the Sun, because they are farther away from the Sun. It make its gravitational pull weaker to the farther planets. That means that the outer planets take longer to orbit the Sun.
Some planets take longer to orbit the sun because they are farther away giving them a longer path to travel.
The outer planets take longer.
The outer planets take longer to orbit the Sun, because they are farther away from the Sun. It make its gravitational pull weaker to the farther planets. That means that the outer planets take longer to orbit the Sun.
The outer planets take longer to go round because (i) they are further away and (ii) they move more slowly because the Sun's gravity is weaker out there.
The time of revolving depends on the distance so that the more distant planets take longer to get round, and as well as that they move more slowly, which makes them take even longer. The record is held by the dwarf planet Sedna, which takes 11,400 years for one revolution of its highly elliptical orbit.
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.
It takes longer because the planets are differant distances away from the sun, the greater the difference the longer it take
Earth takes 365.256 days (1 sidereal year) to complete an orbit round our Sun.
Because of the Sun's gravity.
light because the sun is warm and round
