Merkür-Mercury

Mercury is the Planet closest to the Sun among the 8 planets in our Solar System. Due to its proximity to the sun, it rotates very quickly and completes a year in 88 days. Mercury is a terrestrial planet, just like Earth. The thickness of its outer crust reaches 400 km, and the magnetic field of this planet is 1 percent of the earth. Don't be fooled by the fact that Mercury is the closest planet to the Sun, contrary to popular belief, it is Venus, not the hottest planet in the Solar System. Mercury is caught in a gravitational lock due to its proximity to the Sun, so it always faces the same side of the sun and the other part always faces the darkness. The sun-facing side is around 427 degrees Celsius, and the dark-facing side is around -173 degrees Celsius. The main reason for the significant temperature difference between the two surfaces is that Mercury does not have an atmosphere to dissipate the heat.

.Mercury's surface is made up of craters, plains, and cliffs and has a grayish-brown color. In part, the Earth's satellite has similar surface shapes to the Moon. Unlike Mercury's size, it has a very large density because 70% of the planet is made up of metals. Today, only 2 spacecraft have been to Mercury and Mercury has been recognized with the information received from them. Apart from these, no pictures of Mercury could be taken with telescopes in Earth orbit, because it was feared that its proximity to the sun would spoil the lenses of the telescopes

Today, we expect the BepiColombo spacecraft, which was launched to learn more about Mercury and is on its way, to reach its target in 2025 and to open the veils of mystery about Mercury with important measurements it will make about Mercury.
