What else can I help you with?
What stops planets from flying away from the solar system?
The Gravitational Pull
What force stops the planets moving away from the sun?
Gravity
What if the sun did'nt have gravity?
then all of the planets will just fly away in space they will just keep on flying.
What keeps the solar system in balance?
Gravity and motion. Gravity pulls the planets in and keeps them from flying away, while the velocity of the planets keeps them from being sucked in completely.
Is air between planets?
No, there is no air or atmosphere in the vast empty space between planets in our solar system. Space is a vacuum, meaning it is empty of gases and molecules. The thin atmosphere around planets like Earth fades into space as you move away from the planet.
Why do outer planets have a thicker atmospheres than the inner planets?
Gravity is the force that keeps an atmosphere in place, surrounding a planet. Since there is no actual roof or container holding in the atmosphere, gas can always leak away into outer space, if it is not held in place by gravity. So the stronger the gravitational force, the more atmosphere can be retained. Large planets have a lot of hydrogen in their atmosphere, but hydrogen leaks away from smaller planets. Large planets attracted more gas when they were originally formed, as well. Remember that the solar system itself, and everything in it, originally condensed out of an interstellar cloud of gas and dust.
Why do inner planets have thinner atmospheres than the outer planets?
An atmosphere is a layer of gas that surrounds a planet; this gas is attracted by gravity and is greater in volume depending on the strength of the gravitational field and the temperature of the atmosphere. The inner planets generally have less mass, resulting in a less strong gravitational field, and a warmer atmosphere meaning the atmosphere is thinner than the colder, larger outer planets.
Why do small planets have little atmosphere or no atmosphere?
The rocky or terrestrial planets have less atmosphere (but more breathable atmosphere) than the gas giants have, for two reasons. First, they are smaller, and therefore have weaker gravitational fields, which makes it easier for gas to leak away into space, and secondly, they are closer to the sun and therefore hotter, and the additional heat causes gas to expand, thus also contributing to its escape into space.
Do all planets have wind?
Not all planets have wind. Wind is caused by the movement of gases in an atmosphere, so planets without a significant atmosphere, like Mercury or the Moon, would not have wind. Additionally, the intensity and frequency of wind can vary greatly depending on factors such as atmospheric composition, temperature gradients, and surface features.
How does the planets' distances from the sun affect their atmosphere?
The distance from the sun affects a planet's atmosphere by influencing its temperature and composition. Planets closer to the sun tend to have hotter temperatures, leading to more volatile gases evaporating and potentially thinner atmospheres. On the other hand, planets farther from the sun have colder temperatures, which can result in more stable atmospheres with heavier gases.
How many planets away from the earth is the moon?
No planets away.
Why don't other planets have atmosphere?
Other planets may not have atmospheres due to a variety of factors such as their distance from the sun, composition, size, and lack of magnetic field to protect the atmosphere from being stripped away by solar wind. Additionally, some planets may have had their atmosphere stripped away over time due to various geological processes or impacts from celestial bodies.
