Important Facts of Mercury

Mercury location in the Solar System:

Mercury is the closest planet from the Sun in the Solar System. Mercury is smallest planet in Solar System.  Information available so far, there is no life on Mercury as the surface temperature is around 800 degree Fahrenheit.  No any known life can sustained in that temperature.

The average distance of the Mercury from the Sun is about 57.9 million kilometers (36 million miles)

This distance is equivalent to 0.39 Astronomical Unit.

Mercury Position Solar System                            

Mercury is smallest planet in the solar system, its slightly larger than Earth’s Moon and it’s named after the Greek God Hermes, translated into Latin as Mercurius (Mercury), God of Commerce, messenger of the Gods, mediator between Gods & mortals.

Mercury mean Diameter is 4880 km.

Five Important facts of Mercury

Mercury Rotation & Revolution

1.     The average distance of the Mercury from the Sun is about 57.9 million kilometers (36                 million miles)

2.     Mercury rotates counter clockwise like other planets except Venus (rotates in Clockwise)         axis.

3.     The Mercury takes 59 Earth day to complete one rotation.

        Long days, short Year, one day - night cycle on Mercury takes 175.97 Earth days.

        The Mercury rotates counter Clockwise on its axis at a speed of 10.892km / h (3.026 m /s)

4.     Mercury takes 88 (Earth) days to complete one revolution of the Sun. One year on                     Mercury is just 88 Earth days.

        The Mercury revolves around the Sun and at a speed of 47.362 km/s or 170,503.2                         km/hour

5.     The mercury's axis tilts to 7  to its orbital plane.

Surface Geology

Mercury is a rocky planet, also known as a terrestrial planet, Mercury has a Solid, crafted surface, much like the Earth’s Moon.

Atmosphere of Mercury

Mercury's thin atmosphere, or exosphere, is composed mostly of oxygen (O2), sodium (Na), 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.

Life

No evidence for life has been found on Mercury. Daytime Temperatures can reach 430 degrees Celsius (800 degrees Fahrenheit) and drop to -180 degrees Celsius (-290 degrees Fahrenheit) at night. It is unlikely life (as we know it) could survive on this planet.
