Toledo Mercurys was created in 1947.
By volume, they are oxygen and sodium.
it is made of small amounts hydrogen helium and oxygen. it has almost no atmosphere because of the planets gravity.
Mercury's atmosphere is extremely thin compared to Earth's. It is composed mostly of oxygen, sodium, hydrogen, helium, and potassium, but its overall density is about 100 trillion times less than Earth's atmosphere. Mercury's weak gravity isn't strong enough to retain a thick atmosphere like Earth's.
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
A thin atmosphere is thin and a thick atmosphere is thick
Eris has a very thin atmosphere
Pluto has a very thin atmosphere.
one day on mercury is 58 earth days and 12 hours1.) mercurys atomic number is 802.) mercurys atomic symbol is Hg3.)mercury is toxic4.)mercury is sometimes used in thermometers5.)mercury is shiny or silvery6.)mercurys melting point is 234.32 kelvins
Ganymede, Jupiter's moon, has a thin atmosphere composed mostly of oxygen and hydrogen. These gases are present in very low concentrations compared to Earth's atmosphere. Ganymede's tenuous atmosphere is believed to be created by charged particles interacting with the moon's surface.
The atmosphere on Mars is thin because it is 95.72% carbon dioxide.
