Interesting Facts About Mercury

Mercury is a planet and it is the closest neighbor to the sun. It is the smallest planet in the solar system. Being the nearest planet, it rotates the sun much quicker than any other planets in the solar system and it takes only 88 earth days to complete one rotation of the sun.  Mercury is the second hottest planet next to venus. So the venus experiences higher temperature than mercury. The temperature of mercury during day time is 800°C and during night time it decreases to 270°C. Let see some of the interesting facts about mercury

Mercury is the nearest planet to the sun compared to other planets in the solar system. But it is not much closer to the sun, it is 36 million miles far away from the sun. The shape of mercury looks like heavy metal with the solid iron core in the surface. Once in seven years, we can see mercury from the earth itself while passing the face of the sun and at the same time the planet comes in between the sun and earth, Scientist says that this event is called as a transit.

Interesting facts about mercury:

1. Mercury is the smallest planet:

  • Mercury is the smallest planet in the solar system. The size of the small planet is approximately 4,876 kilometer in diameter.
  • Before mercury, Pluto carried the title for the smallest planet in the solar system. But after Pluto scratched out of the planet’s list now mercury holds the title for the smallest planet.
  • A research found that the size of the mercury is exactly equal to the size of the continental United States.
  • The earth’s moon is smaller in size than mercury. Similarly, Saturn’s moon Titan is bigger in size than mercury.
  • Earth is 18 times bigger in size than mercury.

2. Lack of atmosphere in mercury:

  • Mercury has a very thin atmosphere around it that means there is no air present on the planet.
  • Sun stops the atmosphere passing through the mercury by emitting lots of solar radiation. So without any gases, human beings cannot live in mercury.
  • But in earth atmosphere protects humans from solar radiation.
  • It has very less gravity. Gravity present in the mercury is just 38% of earth’s gravity. If a person goes there means, Person weights reduce to 1/3 of the what he had in the earth.
  • The sun rays passing on the mercury is 10 times higher than the sun rays passing on the earth.

3. Oldest planet:

  • Mercury was invented back in 3000 B.C by ancient civilizations. Ancient civilizations are Sumerians and Babylonians.
  • It was first observed by Galileo through the telescope in the early 1600s.
  • Only two spacecraft reaches the mercury until now. In 1973, spacecraft Mariner 10 was sent to mercury. it clicks a close picture of the planet and also identified that the planet had an iron core and magnetic field.
  • Messenger Probe was another spacecraft launched to mercury in 2004.
  • We cannot constantly send spacecraft to mercury because the radiation from the sun slows down the speed of the spacecraft and also destroy it.

5. Wrinkles present in mercury:

  • Mercury has a lot of wrinkles present in the layer. In the early stage iron core present in the mercury is too hot and gradually it starts to cool down, then Its core started to contract.
  •  Iron core of the mercury is cooled and contracted, which result in the form of a lot of wrinkles present in the surface.

6. Cratered planet:

  • In early-stage, scientist believed that the mercury layer is very smooth, but in the year 1973 mariner 10 spacecraft was sent to mercury which took pictures of the layer that shows numerous craters.
  • The largest crater on the mercury is Caloris basin which is approximately 1550 km in diameter.
  • Mercury also named as the most cratered planet in the solar system.

Other important facts:

  • The distance between the mercury and the earth is 57million miles or 92 million kilometers.
  • Due to the thin atmosphere in mercury, it does not have any rings or moons. Mercury and Venus are the two planets that do not have any moons.
  • Recent research found that the mercury has a tail in the back, Scientist says that the mercury revolves with a long comet-like tail behind it. comet is made up by sodium atoms, that continuously pushes off the sun’s radiation.
  • Mercury has a molten core in the surface. Iron core present in the mercury is fully molten and also having molten iron. Mercury has the most number of the iron core than any other planet in the solar system.
  • A research found that mercury has ice and organics, even though the planet is so close to the sun. scientist found that a lot of ice present in the craters where they cannot receive any solar radiation. Organics also found in the surface, it is the building a block of life.
  • An inner part of the shell is made up of iron and outer part of the shell is made up of silicate.
  • 59 days on Earth is equal to one day on mercury.
  • We cannot see mercury on Hubble space telescope. This is because the sun’s radiation can damage the electrical components of the telescope.
  • The shape of the mercury is elliptical in shape.
  • The size of the sun appears in the mercury is 2.5 times larger than the earth.

A famous quote says that ” I would rather be Mercury, the smallest among all eight planets that revolve around the sun than the first among five moons that revolve around the Saturn”These are some of the interesting and unknown facts about the planet Mercury. We will constantly update more unknown facts about the planet Mercury.
