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.

How does the length of a year compare between inner and outter planets?

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.


Which planets has longer time of revolving arround the sun?

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.


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.


Why does it takes some planets only days to revolve around the sun and other planets more than one hundred years?

It takes longer because the planets are differant distances away from the sun, the greater the difference the longer it take
