Mercury has no atmosphere.
Mercury's atmosphere is composed mainly of oxygen (42%), sodium (29%), hydrogen (22%), helium (6%), and potassium (0.5%). It is very thin and has a pressure about 1/100,000 compared to Earth's atmosphere.
it makes it very hot and oncreases the amount of radiation
Titan is the only one of Saturn's moons that has an appreciable atmosphere. It is most like earth's atmosphere in its high concentration of nitrogen (98% compared to Earth's 78%).
Mercurys mean radius is around 2,439.7 km, which is around 38.39% of earth radius or 0.3829 Earths. Mercurys mass is around 3.3022×10 to the 23 kg, around 5.5% of earths mass or 0.055 Earths.
Mercury's gravity is approx 40% of Earth's.
If Mercury's volume was compared with Earth's volume, then 18 Mercurys could fit inside the Earth.
Mercury's atmosphere is composed mainly of oxygen (42%), sodium (29%), hydrogen (22%), helium (6%), and potassium (0.5%). It is very thin and has a pressure about 1/100,000 compared to Earth's atmosphere.
By volume, they are oxygen and sodium.
No, it has hardly any atmosphere.
The year on the planet Mercury is very short. A year on this planet lasts 88 days compared to 365 days on Earth.
balrgh
it is made of small amounts hydrogen helium and oxygen. it has almost no atmosphere because of the planets gravity.
The part of the sun that can be compared to Earth's atmosphere is the corona. The corona is the outermost layer of the sun's atmosphere, characterized by its low density and high temperature, similar to how Earth's atmosphere extends into space and has varying temperatures at different altitudes. Both the corona and Earth's atmosphere interact with solar and cosmic radiation, influencing space weather and conditions on Earth.

Mercury rotates in about 58.65 Earth days.
Mercury is the smallest planet compared to the other ones
Compared to Earth's, it has:* A high pressure * An extremely high temperature
