This layer is warmer in its lower parts because the ground heats it. It's named after the Roman god Mercury. The pressure of Mercury's atmosphere was determined to be about 10−12 bar (compared to the 1 bar atmospheric pressure at sea level on Earth). Due to the planet's very thin atmosphere, the planet. Atmosphere. Mercury's outer shell, comparable to Earth's outer shell (called the mantle and crust), is only about 400 kilometers (250 miles) thick. Venus's thick atmosphere of almost pure carbon dioxide is more famous for absorbing the Sun's heat very effectively, making the planet hotter even than Mercury and confounding science fiction . Mercury's exosphere is made up of oxygen, sodium, hydrogen, helium and potassium that are all whipped up from the planet's surface by the solar winds. There is considerably more atmosphere in Venus than Mercury, so its temperature can be much higher. To be sure, Mercury's surface pressure is less than one-trillionth that of Earth. -128 F (-88 C) would prevail at Venus's surface if there is no atmosphere on the planet. The temperature can drop to minus 300 degrees Fahrenheit. Mercury's thin atmosphere is constantly being "blown away" into space by the pressure of sunlight and by the solar wind.
