Which inner planet has enough gravity to hold on to most gases?

Earth has enough gravity to hold on to most gases in its atmosphere. This is due to its moderate gravitational force compared to other inner planets like Mercury, Venus, and Mars.


Do the inner planets have gravity?

Yes. All planets have gravity. Earth is one of those inner planets.


What are outer planets made off?

I think you mean of? Anyways if so, they are made up of gases. Only the outer planets are able to have gases because its cool enough there. Inner planets get more sun so its too warm for gas planets in the inner part. Hope this helped.


For what reason did the inner planets not collect gas like the gas giants did?

The inner planets did not collect gas like the gas giants because the intense heat and solar wind from the young Sun blew away most of the lighter gases, leaving mostly heavier elements to accrete into rocky planets. The gravity of the inner planets was not strong enough to hold onto light gases due to their proximity to the Sun.


What divideds the inner planets?

gravity


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.


Are the inner and outer planets different?

The inner planets are all rocky planets. The outer planets are completely made up of gases. The inner planets are much smaller than the outer planets.


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.


How do the inner planets diffrer from the outer planets?

the inner planets made up of rocks while the outer planets are made up of gases and liquids.


What reasondid the inner planets not collect gas like the goants did?

The inner planets are closer to the sun, so they are warmer. That means that the gas molecules haVe enough energy to escape the gravitational field of the planet. Jupiter is made mostly of hydrogen gas which is very light, but it is also very cold, so the molecules don't move around very fast and cannot escape the gravity of Jupiter. The other gas planets are even colder. If you look at the gases that ARE on the inner planets, you will find that they are generally heavier, like nitrogen, oxygen and carbon dioxide so their molecules cannot gain enough speed to escape the gravity of the planet.


What force holds inner planets tightly to the sun?

Gravity :) (Gravity also holds the outer planets tightly to the Sun.)


How are the compositions of the inner planets and outer planets different?

A basic, simplified answer is: The inner planets are mainly rock with iron cores. The outer planets are mostly gas, or liquefied gases.
