Planet Mercury (Smallest And Oldest Planet In The Solar System)

  • May 08, 2019

Today, we have to discuss the planet Mercury of the Solar System. This planet is known as the smallest and oldest planet in the Solar System. Mercury is known as the celestial planet in the orbit of the Earth, and is 28° away from the Sun observed from Earth. So let's get some information about Mercury.

This planet is locked very strongly in the 3: 2 spin-orbit resonance with the Sun. Mercury converts exactly three times on its axis for every two revolutions made around the Sun. At the axis of this planet, there is almost any small pellet from the Solar System's planets. And its orbit is the largest of all the known planets in the eccentric solar system. The surface of this planet appears to be very pebbly and it is in the appearance of the moon. That suggests that it is billions of years of geological disabled.

Planet Mercury (Smallest And Oldest Planet In The Solar System)

Mercury has no known natural satellites on this planet. On this planet, two spacecraft have been visited. Mariner on this planet made 10 flew in 1974 and 1975, and the messenger started in 2004. Four years after the collapse of its fuel on April 30, 2015, and four years before the planet's collapse, the circulation of Mercury is 4000 times. BepiColombo spacecraft plans to reach this planet in 2025.Mercury is believed to be one of the four astral planets in the Solar System. This planet is found to be rocky like the Earth. Mercury is considered to be the smallest planet in the Solar System with the tropical radius of 2,439.7 kilometers. This planet contains about 70% of the metal and 30% silicate content. Mercury's density is the second highest in the Solar System at 5.427 g / cm, which is equivalent to 5.515 grams / cm of the Earth's density, Looks slightly lower than that. A special feature of this planet's surface is the presence of numerous concentrated mountains, which extend in length to some hundred kilometers.

Mercury can be approximately 1/6 of the Earth's mass and its mass and thousands of kilometers away from it. The nearest temperature of this planet may be 2,500 to 3,500 or between 10,000 and higher. Most surfaces of this planet can be evaporated at such temperature, which creates an atmosphere of "rock vapor" that can be removed by solar wind. Mercury's surface looks similar to that of the Moon, which shows grass-like grounds and heavy cratering. The October 2008 MESSENGER flyby data for Mercury's surface-to-surface nature has given much appreciation to researchers.

Mercury has two geographically different ground areas. Gently rolling, mountainous plains in craters are the oldest visible surfaces of Mercury and predict heavy wastes. The Intercrater Plains seem to be erasing many earlier cutters and about 30 km below the diameter shows the general shortage of small craters. The simple grounds of Mercury are the same albedo as the old intercrater plains. An unusual feature of this planet's surface is a number of contractions that cut off the plains. The surface temperature of this planet ranges from -173 to 427 ° C.

The intensity of sunlight on the surface of Mercury is found in solar between 4.59 and 10.61 times. Although the temperature of sunlight is generally very high on the surface of the planet, observations hardly indicate that ice exists on Mercury. The origins of ice on the body are not known yet, but the two potential sources are from the outer part of the planet or the effects of comets from the inner part of the planet. Mercury is known as a very small and warm planet. The surface of this planet is an outer spacecraft, which contains hydrogen, helium, oxygen, sodium, calcium, potassium and other on ground pressure of less than 0.5 NPA.

Mercury average receives 116 Earth days. But this interval can be due to the whimsical orbital of the planet from 105 days to 129 days. The planet can close as much as 82.2 gig meters on Earth and it is gradually decreasing. Buda is the closest planet of 46% of the Earth. Mercury's average apparent magnitude is 0.23. This planet is like many other planets and bright stars, Sun is found during eclipse. On August 3, 2004, Mercury's second NASA mission, MESSENGER, was launched. This mission has been launched to explore the high density of Mercury, its geological history, the nature of its magnetic field, its origin form, its snow on its poles, and where it has a weak environment.

The size of the planet Mercury is slightly more than the planet's moon. This planet takes 59 Earth days to do a perfect rotation. Mercury goes a year faster on the planet. Because it is the closest planet to the Sun, it does not take much time to travel almost all the way. This planet is found to complete a revolution around the Sun in just 88 Earth days. The planet's radius is 1,516 miles, the planet Mercury is slightly more than 1/3 the width of the Earth. The Buddha planet is close to 43 million miles from the Sun. The planet Gravitational Surrounding the Sun, about 4.5 billion years ago, the gas and dust were rotated together to form a small planet. Like its fellow fixed planets, Mercury has a central part, rocky mantle and a solid crust.
