Jupiters do not have land, so they cannot land. But most of them have some large satellites. There is a solid "ground".

Anonymous users2024-02-14It is a planet made mainly of gaseous matter.
A planet like the Earth with a solid surface is called a rocky planet, and the outside is wrapped in a layer of gaseous material that is not too thick, and for the Earth, it is called the Earth's atmosphere. The greater the mass of the planet, the more and thicker the atmosphere that can be gravitationally attracted and retained. The more and thicker the gaseous matter, the greater the mass of the planet, the greater the gravitational pull, which in turn attracts more gaseous matter.
So, the more mass the planet has, the more gaseous matter is wrapped around it. When a planet's mass is large enough and its gravitational pull is strong enough, the gaseous matter wrapped around the outside will account for the majority of the planet's mass compared to the solid matter at the core. At this time, the planet is called a gas planet.
Therefore, gaseous planets, first, must have a large enough mass so that gaseous matter becomes the majority of the mass of the planet; Second, the surface is completely gaseous, and no solid matter can be seen; Third, the gas composition is mainly hydrogen and helium, which is not much different from the gas composition of stars, but is obviously different from the gas composition of the atmosphere of rocky planets; Fourth, gaseous planets have a huge volume compared to solid rocky planets.
In the solar system, there are 4 gas planets, namely: Jupiter, Saturn, Uranus, and Neptune. Their common features are:
The mass is huge, there is no solid surface, and there is a solid (possibly rocky) core in the center, which has a very small percentage of the core mass compared to the mass of the planet.
For example, Jupiter's inner core mass accounts for less than 5% of Jupiter's total mass, Saturn's inner core mass does not exceed 20% of Saturn's total mass, and Uranus's rocky core mass is not very certain, but it is generally believed to account for only 5% of Uranus's total mass, and Neptune is about the same.
To use a misguided analogy, a gaseous planet is a large cloud of gas wrapped around a small rock.

Anonymous users2024-02-13Gas giants, sometimes called Jovian planets, planets other than Jupiter, or giant planets, are large planets that are not composed of rocks or other solids. Hope to adopt.
The arrival of night is due to the fact that the autobiography of the Earth is that we are on the opposite side of the Sun, the Moon can reflect the sun's light, but the Moon is a satellite of the Earth, not a planet. The reflective planets we usually see are generally Venus at dawn and Chang Gung at evening (in fact, they are formed by Venus reflecting the sun's light at different times), and most of the stars we see at night are stars. Most of them are brighter than the sun, but they are too far away from us, and writing that they are still moving away from us at a rapid pace so we feel that they are not as bright as the sun, and much smaller than the sun. >>>More
The Earth is a planet and ranks third in order of proximity to proximity to the Sun. >>>More
The planet is out of the gravitational range of the star in its motion around the star. Taking the solar system as an example, planetary escape means that all eight planets have left the solar system, and the fundamental reason is that the gravitational pull of the stars becomes smaller, and the planets cannot be restrained from continuing to move in their original orbits.
Generally, the International Committee on the Nomenclature of Small Bodies named the asteroid with the number 8615 after important people and events, such as the asteroid numbered 8615 is named "Bajin".
It is formed by the fusion of solar nuclei, and their arrangement is regular. The universe is very mysterious, it is like a mysterious masked man, waiting for us to uncover its mystery through scientific and technological research and exploration. In the countryside or on the outskirts of the city, when the air quality is better, we can often see the stars at night. >>>More
