Do terrestrial planets have more moons than the outer gas giants?
Terrestrial means on Earth so Earth is the only terrestrial planet This is incorrect, the first 4 planets are terrestrial as they are solidly bound planets. Pluto was also a terrestrial dwarf planet. Any planet can have moons but due to the gas giants having larger gravitational forces they have traditionally gathered more moons. Thusly, no.
Why do the inner planets have fewer moons?
The inner planets have fewer moons because they formed closer to the Sun where the gravitational pull was strong enough to prevent significant amounts of material from coalescing into moons. Additionally, the inner planets' gravity is not strong enough to capture passing objects as moons like the gas giants, which are located farther out in the solar system.
How many planets have fewer than ten moons?
In our solar system, four, all four inner planets. Mercury and Venus have no moons, Earth has one and Mars has two.
Why do the inner terrestrial planets have far fewer moons than the gas giants?
The smaller planets (Earth and Mars) have a smaller gravitational attraction than the larger planets, which limits the potential orbital distance. They are also closer to the Sun, where there are comparatively fewer asteroids, and where the gravity of the Sun and nearby planets make stable orbits less likely. While the Moon is thought to be made from material once part of the Earth, the tiny moons of Mars (Phobos and Deimos) are likely asteroids that came close enough to the planet to be held there. They are in comparatively low orbits, only 6000 and 23000 kilometers, respectively, from the Martian surface.
What are planets good for?
LIFE. Also that many fewer asteroids floating around that could slam into earth and end all life.
Why do some planets have more moons than other planets?
All matter has a gravitational pull. Even you have a gravitational pull too. It is just that since your mass isn't quite as big as the Earth, your you can't see things moving towards you. When you jump, the Earth pulls you down. THat is cause the Earth is considerably bigger than you and you are attracted to the Earth. Some planets have more moons because of their mass. Since they are bigger and more massive, they pull much more stuff around them to orbit.
How do the periods of rotation and revolution for the gas giants differ from those on Earth?
This is a hard question...but the answer is:the gas giants are further away,so the the sun has less gravity power on the gas planets,so the revolution is slower than the inner planets (including Earth). However, the rotation period is faster than Earth. Jupiter's is 9h 55m, Saturn's is 10h 38m, Uranus' is 17h 14m, and Neptune's is 16h 6m.
What are ways you can increase the force of gravity on earth?
The force of gravity is greatest between two masses whose product is greatest, and which are closest together. You're already as close to the earth's total mass as you can get, and there's nothing you can do to change the earth's mass. So the only way to increase the mutual force of gravity between the earth and another body is to increase the mass of the secondary body. In fewer words: Eat more. Get heavier.
Why is there most air closer to the surface?
Most of the Earth's atmosphere is concentrated near the surface due to gravity. The force of gravity pulls air molecules towards the Earth, making the air denser at lower altitudes. As you move higher in the atmosphere, the air becomes less dense because there are fewer air molecules present.
How many planet has less satellite than earth?
Mercury and Venus have no moons, the earth has one, mars has a few, and the gas planets have dozens
Do all planets have craters in them?
No, not all planets have craters. Craters are often found on solid bodies with little to no atmosphere, like the Moon and Mercury. Planets with active geology or thick atmospheres, like Earth and Venus, may have fewer visible craters due to ongoing processes that can erase them.
Does the mass of a planet seem to affect how many moons it has and why?
Yes, the mass of a planet often affects the number of moons it has, primarily due to gravitational influence. Larger, more massive planets, like Jupiter and Saturn, have stronger gravitational fields that can capture and hold more moons. Additionally, their size allows them to attract more debris and smaller celestial bodies, which can coalesce into moons over time. Conversely, smaller planets like Mars and Mercury have fewer moons because their weaker gravity is less effective at retaining them.
