There are hydrogen and helium from the Solar wind. There are also oxygen, sodium and potassium from chemical and radioactive processes on the planet's surface.
The planet Mercury is composed of rock. Its close proximity to the sun prevents any kind of gaseous atmosphere from forming.
By volume, the gases are:Oxygen (42%),Sodium (29%),Hydrogen (22%),Helium (6%),rest (traces).
i need an answer
A moonless planet. In our Solar System, Mercury and Venus do not have a moon.
Its kind of tricky but its Mercury
Mercury Kind of tough, since the sun is a star and most would consider it the beginning of our solar system. The closest planet to the Sun however, is Mercury
78% nitrogen 21%of oxegen 3% carbon dioxide radon,heilium
Mercury has a surface pressure that is near enough zero or a vacuum, since the planet holds no atmosphere due to its small size.
This planet is rocky. It has many features such as highlands, entire plains, crater, cliffhangers, and ridges.
Mercury has very few gases. What are present are:-42% Molecular oxygen29.0% sodium22.0% hydrogen6.0% helium0.5% potassiumand Trace amounts of argon, nitrogen, carbon dioxide, water vapor, xenon, krypton, & neon
The planet Venus has nitrogen, carbon dioxide and smaller amounts of other gases. Most of the gas is carbon dioxide.
it is all to do with what kind of gases the planet has in its atmophere unless i know the planets name thats all can say
