Why does it take the outer planets so long to orbit?

Answer 1

The larger the radius of your orbit from a common center, the farther the distance you would be traveling around that object as is the case with planets farther from the sun. Substantially, planets have lower masses than the sun, thereby weaker gravitational interaction, lower space velocity, which makes them "creep" slower in their orbits. If you place a star, say the same mass as the Sun in the orbit of Neptune, the time it takes for the two stars to complete one revolution around each other would be shorter.

Answer 2

The first reason is that their orbits are bigger than those of inner planets and the second reason lies on the fact that they experience week gravitational pull from the sun. In turn, they have slow acceleration and hence, move at lower speeds.

Answer 3

Outer planets are farther from the sun, so they have larger orbits. Their greater distance from the sun means they travel more slowly in their orbits, taking longer to complete a full revolution. This leads to their longer orbital periods compared to the inner planets.

Answer 4

It takes long for the outer planets to orbit around th Sun because, they are far from it, and the Sun's gravity is weaker, so they accelerate more slowly and have lower orbital speeds.

Answer 5

The outer planets are so far away from these sun, they have a longer rotation period. Plus, the sun's gravitational pull is weaker out there.

Answer 6

Because the outer planets don't have a strong gravitational pull towards the sun
