Why do further planets have longer years

Answers:
Because the farther away from the sun, the longer it will take to travel around it in an orbit. Also the planets move slower when further away due to less gravitational pull. Believe it or not, there are dwarf planet far out in the oort cloud that take thousands of Earth years for one of there years. If you do not know what the oort cloud is, it is the furthest region, where comets, some asteroids, and a few dwarf planets are found, and at the end of the oort cloud is where the sun's gravitational dominance ends. Oh, and I'm a 14 year old answering this.

  • Why do the planets further the sun have longer years?
    because more away from the sun the longer time it take for the sun to orbit that planet
  • Can a planets day be longer then its year?
    Yes. In fact, Venus has a longer day than its year.
  • Which planet has a longer day then year?
    Venus
  • Why do the outer planets have longer years than the inner planets?
    Because the closer to the sun the shorter distance it has to go like on a race track not everyone starts at the same place that way they meet the same length
  • What planet has longer days than planet year?
    Venus. The day is very long - 243 Earth days, and it's year (it's orbital period to travel once around the sun) is 225 Earth days, which makes a day on Venus longer than it's year! Interestingly,...
