no 2nd Answer: While some of our large planets are made of gasses, Earth's moon, 'Luna', is mostly rocky.
The "exoplanets" known as "Hot Jupiters".
The exoplanets called "Hot Jupiters."
No planet is made of glass, as far as I know. The giant planets - Jupiter, Saturn, Uranus, Neptune - are large, and made mostly of gas. However, they are not fast-moving.The inner planets - Mercury, Venus, Earth, Mars - are slow, fast-moving, and made basically of rock.
No, those are the outer planets.
Solar Gasses. When a star explodes as a nova or a super-nova, it puts out large amounts of gasses that can re-condense to form planets and/or another sun(s).
They are very large, and consist of mostly gases.
The planets that are large, fast-moving, and mostly made out of gas are known as the gas giants in our solar system: Jupiter and Saturn. They are characterized by their massive sizes and thick atmospheres primarily composed of hydrogen and helium. Uranus and Neptune, while also gas giants, are classified as ice giants due to their higher concentrations of water, ammonia, and methane ices. All four of these planets have rapid rotation speeds, contributing to their dynamic atmospheres.
Meteorites.
When the sun was young it released an intense solar wind. This prevented the inner planets from developing thick atmospheres like the outer planets. The outer planets, however, were spared from this fate, and were able to accrete large quantities of gasses.
All planets have gravity- Some more than Earth, some less. Other planets that are large enough do have air- but not made up of the same gasses as Earth.
