it's small size and low gravity
The gas giant planets have stronger gravity, which makes it harder for anything to escape, and are colder, which means that even with similar gravitational fields, gas molecules might not achieve escape velocity.
because the gravity keeps the giants planets' gases from escaping.
because the gravity keeps the giants planets' gases from escaping.
It feels bad about how ugly it looks stupid. DAH
because if u have enough gas in one area it creates mass and causes it to stay in the gravity field of a planet
Mercury doesn't have a gas giant.
Jupiter has a gravity which is substantially greater than on Earth. The other gas giants have gravity which is similar to Earth's. Mercury, on the other hand, has a very weak gravity: around 38% compared to Earth. Also, being so close to the Sun it is blasted by the Solar wind. These two factors have stripped Mercury of its atmosphere.
Mercury argon gas does not exist.
The gas-planets are much larger so they have a much stronger gravitational field, and they are able to hold on to their gas. Mercury is very close to the Sun and the gravitational force from the Sun is strong. Also any atmosphere on Mercury would have been subject to the tidal forces caused by the gravity being stronger on the side facing the Sun and weaker on the opposite side.
The planet Mercury's escape velocity is 4.3 kilometers per second. The escape velocity of the Earth is 11.2 kilometers per second.
the planet is a solid but mercury is a gas as well
