What is Mercury composition of atmosphere?

What is Mercury composition of atmosphere?

Atmosphere. Instead of an atmosphere, Mercury possesses a thin exosphere made up of atoms blasted off the surface by the solar wind and striking meteoroids. Mercury’s exosphere is composed mostly of oxygen, sodium, hydrogen, helium, and potassium.

What is the temperature range on Mercury?

It is understood that the sunny side may reach temperatures of 750 to 800 degrees F., while the nighttime temperature plummets to nearly -330 degrees F. The average temperature on Mercury is a balmy 354 degrees F.

How has Mercury been explored and research?

Two spacecraft have visited the planet Mercury so far. The first was called Mariner 10. During 1974 and 1975, Mariner 10 flew by Mercury three times and mapped about half of the planet’s surface. Mariner 10 also discovered Mercury’s thin atmosphere and detected its magnetic field.

What planet is known for retrograde rotation?

Venus
As viewed from a position in space north of the solar system (from some great distance above the Earth’s North Pole), all the major planets revolve counterclockwise around the Sun, and all but Venus and Uranus rotate counterclockwise on their own axes; these two, therefore, have retrograde rotation.

What is the hottest temperature ever recorded on planet Mercury?

800 °F
Mercury is hot. If we’re being quantitative, it’s actually extremely hot! As the closest planet to the Sun, it completes an orbit in just 88 Earth-days, achieving a maximum temperature during the day of a whopping 700 Kelvin (427 °C / 800 °F) at its hottest, equatorial locations.

Can humans go to Mercury?

No, Mercury has been visited by spacecraft from Earth, but no human has ever gone into orbit around Mercury, let alone stepped on the surface. However, the temperatures on Mercury are much greater. During the daytime, the surface of Mercury at the equator rises to 700 Kelvin (427 degrees C).

What planet rotates the slowest on its axis?

What is the Slowest Planet. Venus, which is floating higher each evening in twilight, low in the west, is the slowest-spinning body in the known universe. If you walked along a bike path that circles its equator, you’d only need to go four miles an hour to keep night from ever falling on Venus.

Which planet turns the opposite way?

planet Venus
Our neighboring planet Venus is an oddball in many ways. For starters, it spins in the opposite direction from most other planets, including Earth, so that on Venus the sun rises in the west.
