Why does it take Neptune longer than Mercury to revolve around the sun?

Answer 1

Neptune is the farthest major planet from the Sun, at an average distance of 4.5 billion kilometers from the Sun, 30 times farther than the Earth. This makes its orbital path around the Sun more than 30 times as long as Earth's. So even at the same speed as Earth, it would take more than 30 Earth years to make one orbit. In fact, it is much moving much more slowly than Earth, less than 1/5 the speed, and takes 164.79 Earth years.

The basis for planetary orbits is that planets closer to the Sun, regardless of their mass, must move at a higher velocity than those farther out. Mercury's orbital speed is nearly 9 times as fast as Neptune's.

Answer 2

Neptune's orbit is further from the sun than is the Earth's orbit. The path around the sun that Neptune follows is therefore longer, so it takes Neptune more time to orbit the sun than the Earth requires.

Answer 3

Because it is further away from the sun so the distance neptune has to travel to rotate around the sun is far greater than the distance earth or other planets travel. An example would be running your finger around the edge of a quarter, now do the same to a dinner plate.

Answer 4

it is farther away than the other planets. it is like if you walk around a school and another person walks around a desk. neptune is the walk around the school.

Answer 5

Neptune is farther from the sun in comparison to Saturn, so it has a longer orbit rotation

Answer 6

It is because Neptune is much further away from the sun. Mercury's orbit is approx 360 million km whereas Neptune's is 28.3 billion km.
