|
|
Gas giants are more massive than Earth and thus have greater gravitational forces, so they could attract more objects
|
|
|
Gas giants are farther from the sun than Earth, so there are fewer objects in that part of space to attract into orbits
|
|
|
Gas giants are less dense than Earth, so they contain less material that could form natural satellites
|
|
|
Gas giants rotate more rapidly than Earth, so they eject more material that could form natural satellites
|
Detailed explanation-1: -Q. What property of the gas giants planets would account for their having more moons than the number of moons that orbit the Earth? Gas giants are less dense than Earth, so they contain less material that could form natural satellites.
Detailed explanation-2: -How do gas giants affect Earth? Gas giants and their orbit around the Sun are very important for the Earth. With these larger planets orbiting on the outside of the solar system, they make impact with large meteors and asteroids such that the inner planets like Earth are shielded from these large objects.
Detailed explanation-3: -A gas giant is a large planet mostly composed of helium and/or hydrogen. These planets, like Jupiter and Saturn in our solar system, don’t have hard surfaces and instead have swirling gases above a solid core.
Detailed explanation-4: -For a short answer: The giant planets have more moons than the terrestrial planets because of their great masses which result in stronger gravitational fields. And giant planets also occupy greater space and hold larger volumes of mass in their surrounding atmospheres.
Detailed explanation-5: -A large planet such as Jupiter has enough gravity to hold on to most of its hydrogen and helium, which is why these elements dominate the atmospheres of gas giants. But the gravity of Earth isn’t strong enough, so Earth’s early atmosphere of helium and free hydrogen evaporated into space.
Detailed explanation-6: -While terrestrial planets accreted from planetesimals made of rocks and metals, they ended up too small to capture significant amounts of the abundant hydrogen and helium gas in the solar nebula. The jovian planets, however, formed farther from the Sun where ices and rocks were plentiful.
