Inertia combined with the sun's gravity is what causes the planets to travel around the sun. … The closer a planet is to the sun, the shorter its period of revolution. The farther away a planet is from the sun, the longer its period of revolution.
Why do planets have different periods of revolution around the Sun?
Why do planets have different rotations?
The planets all revolve around the sun in the same direction and in virtually the same plane. In addition, they all rotate in the same general direction, with the exceptions of Venus and Uranus. These differences are believed to stem from collisions that occurred late in the planets' formation.
What causes the differences in the period of rotation and of revolution among the planets?
Revolution is the movement of the Earth around the Sun. The Earth takes 24 hours to complete a rotation with respect to the sun. The Earth's axis of rotation is tilted by 23.5 degrees. This tilt causes the different seasons of the year.
What keeps the planets in revolution around our sun?
The sun's gravity pulls the planet toward the sun, which changes the straight line of direction into a curve. This keeps the planet moving in an orbit around the sun. Because of the sun's gravitational pull, all the planets in our solar system orbit around it.
Why do some planets not spin?
There are many planets that don't rotate and they're called tidally locked planets. Tidally-locked planets are so close to their star, their star's gravity holds them in place like Earth holds the moon. One side of a tidally-locked planet always faces its star, and one side always faces away.
What will happen to the period of revolution of the planets if the distance increasing from the Sun?
As the distance of the planet from the sun increases, the period of revolution decreases.
Why do planets have different?
The major reason each planet looks different is that each planet formed at a different distance from the Sun. The planets formed from a disk of gas and dust that circled the Sun. Near the Sun, solar wind and solar radiation heated and swept away most of the gas, so the planets there are small and rocky.
What is the differences between revolution and Rotation?
"Rotation" refers to an object's spinning motion about its own axis. "Revolution" refers the object's orbital motion around another object. For example, Earth rotates on its own axis, producing the 24-hour day. Earth revolves about the Sun, producing the 365-day year.
Why do planets not fall into the Sun?
Paradoxically, it is the Sun's gravity that keeps the planets in orbit around it, just as the Earth's gravity keeps the Moon and satellites in orbit around it. The reason they do not just fall into the Sun is that they are traveling fast enough to continually "miss" it.
