THE MESSENGER OF GOD - MERCURY

About Mercury

"Mercury"

In Roman, the mercury is known as the messenger of God. Mercury is the nearest planet from the sun. The mercury is the smallest planet in our solar system. It has a similar surface as the moon has as it has rocky, barren, and craters too.

Some facts about the Mercury

• As being close to the sun it has, the daytime temperature reaches 400℃(752℉).
• At night, however, the planet without temperature reaches down at-180℃(-292℉).
• It has a very low surface gravity.
• Mercury has no atmosphere, therefore, there is no wind or wheater to speak.
• Likewise, there is no air but it could be underneath.
• The planet mercury has the length of the year of 88 Earth days.
• From the surface of the Mercury, the sun appears as three times larger as viewed from Earth.
• It is only slighting larger than Earth's moons.
• It is more interesting that, on the planet, Mercury the days are longer than Years (Day>Year on Mercury). It takes 59 Earth days.
• One day-night cycle on Mercury takes 175.97 Earth days. Mercury makes a complete orbit around the Sun (a year in Mercury time) in just 88 Earth days.

• Mercury's thin atmosphere is composed mostly of Oxygen(O_{2), Hydrogen} (H₂ ), Helium(He) and potassium(K). Atoms that are blasted off the surface by the solar wind and micrometeoroid impacts create Mercury's exosphere.
• There are no rings around Mercury.
• It is tough to place to live because it has no atmosphere due to this the temperature increase and decreases at a very large scale.
• The Sun appears big from the surface of the Mercury as standing on the surface of Mercury it appears Three times larger than Earth.

Missions to Mercury

• NASA's Mariner 10 was the first mission to explore Mercury. It was also targeted to Venus and Mercury.

  Because of Mercury's elliptical—egg-shaped—orbit and sluggish rotation, the morning Sun appears to rise briefly, set, and rise again from some parts of the planet's surface. Then the same thing happens in reverse at sunset.
