It is more difficult for gases to escape from Jovian planets because they have much stronger gravitational forces due to their larger mass, which means gases are held more tightly to the planet. Terrestrial planets have lower mass and weaker gravity, making it easier for gases to escape into space.
because the gravity keeps the giants planets' gases from escaping.

the gas giant planets have strong gravitational pulls that hold on to their thick atmospheres. Additionally, the high escape velocity prevents the gases from escaping into space. The cold temperatures of these planets also help in maintaining the integrity of their atmospheres.
The space between planets is known as interplanetary space. It is mostly vacuum but can contain small amounts of particles and gases.
Planets closer to the sun have higher temperatures, which causes them to have higher escape velocities. Lighter gases are more easily able to escape a planet's gravitational pull at higher temperatures, resulting in these planets being unable to retain them. Additionally, the solar wind from the sun can strip away lighter gases from planets closer to it.
Hydrogen is the gas most affected by thermal escape in planetary atmospheres. Its low molecular weight makes it more likely to escape a planet's gravitational pull and be lost to space over time. This process is most pronounced for small, low-gravity planets.
Jovian planets do not have a solid surface, therefore their atmospheres are thick all the say to where their surface would be. Their atmospheres have more gasses than those surrounding terrestrial planets.
Because the mass of the planet holds it down.
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.
First, dust, debris and gases, left over from the formation of the sun and the planets. Second, gases and radiation produced by the sun (eg. solar wind). Third, various spacecraft and other technological artifacts, shot into space by humans (eg. the Pioneers and Voyagers launched by NASA).
The atmosphere is held in place by gravity. Other things being equal, the more massive the planet, the harder it is for a gas molecule to escape into space.
