# Why do planets have different periods of rotation and revolution?

## Why do planets have different periods of rotation and revolution?

Each planet takes a different amount of time to travel around the sun. This is called the planet’s period of revolution. 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 the gas giants have a longer period of revolution compared to the terrestrial planets?

Explanation: Since the gas planets are farther from the Sun, their periods of revolution are longer, according to Kepler’s laws.

How does the composition of Earth’s atmosphere differ from the composition of the gas giant planets?

How does the composition of Earth’s atmosphere differ from the composition of the atmosphere of the gas giant planets? Earth has an atmosphere that is composed mostly of nitrogen and oxygen. the gas giant planets have atmospheres that are composed mostly of hydrogen and helium.

### Why do larger planets rotate faster?

Most studies in this area have focused on the inner planets. That gas formed individual spinning disks (from which many satellites formed), and most likely it carried a lot of angular momentum as it fell onto the outer planets’ cores, causing them to spin faster and faster as they coalesced.

How do the planets maintain its position of rotation and revolution?

The Solar System was formed from a rotating cloud of gas and dust which spun around a newly forming star, our Sun, at its center. The gravity of the Sun keeps the planets in their orbits. They stay in their orbits because there is no other force in the Solar System which can stop them.

Why do gas planets rotate faster?

## How do Saturn’s period of rotation and revolution compared to Earth’s?

Orbital Period: 457 Earth years (or 10,759 Earth days) to complete a single revolution around the Sun. In other words, a year on Saturn lasts about as long as 29.5 years here on Earth. However, Saturn also takes just over 10 and a half hours (10 hours 33 minutes) to rotate once on its axis.

What do you think is the main difference between Earth and the other planets that allowed the evolution of the atmosphere allows life to prosper?

An atmosphere is the layer of gases that envelop a planet. On the Earth, it is this envelope that allows organisms to live. CO2 and other gases trap heat and keep the surface warm enough for life to thrive. Oxygen has allowed life to evolve.

Why do planets have different periods of revolution?

The planets are not all the same distance from the Sun, which determines how far they have to travel, and how fast they are moving. Planets farther from the Sun have much longer orbits and are not moving as quickly. So their period of revolution (year) is longer.

### Why are wind speeds on gas giant planets greater than on Earth?

Why do you think the wind speeds on the gas giant planets are so much greater than the wind speeds on Earth? The wind speed are greater because the gas giant planets have a higher rotation speed which creates faster wind speed.Which is why the wind speed are faster on the gas giant planets then earth

How long does it take Venus to make a revolution?

All planets in our solar system vary in the time it takes them to complete a revolution. This is due to their differing distances from the sun. As far as rotation goes, the time varies from nine hours and fifty minutes for Jupiter to 244 days for Venus to make a like rotation.
