Now you will know information that you did not know about Mercury because this planet is considered the smallest planet in the solar system and it is slightly larger than the Earth’s moon in size, and it is also the closest planet to the sun, but in reality this is not the hottest but Venus is the highest temperature and through a field Increase, we will learn about the planet Mercury, which you did not know before.
Information you did not know about Mercury
There is a lot of information about the planet Mercury that many people do not know, and this information is:
- Mercury has no satellites.
- Mercury rotates slowly compared to Earth and it takes about 59 Earth days to make a full rotation.
- Unlike the day, the year passes quickly on Mercury, and this is due to its proximity to the sun, so only eighty-eight days of the earth complete a cycle around the sun, and the year is less than 3 months.
- Among the information you do not know about Mercury! It takes the Earth ninety-nine days to rotate very slowly and make a full rotation compared to the Earth.
- Mercury has been known since ancient times as it can be seen without sophisticated telescopes.
- Mercury has been visited by two spacecraft, Messenger and Mariner 10.

3D view. Solar system isolated on a black background.
Scientists were late in exploring this planet, and this is due to its location, as it is close to the western horizon, and the atmosphere absorbs the light it emits with it, in contrast to the twilight that occurs during sunset. The invisibility makes this subject very difficult to keep track of, but it should be noted that the first information that astronomers learned about Mercury was in 1974 AD, when the Mariner spacecraft appeared to study it.
Mercury movement in the solar system
The distance between the sun and the planet Mercury is about 47.6 km, and the planet is considered one of the closest planets to the sun in the solar system, and the stellar day of the planet is estimated at 58.65 days on Earth, and its stars are equal to 87.97 days per year on Earth.
This means that the day on this planet is about a third of the year, just as the transit on this planet is between the Sun and the Earth and is in the form of a small black dot and must be observed. Scientists have noticed each time that the transit time has advanced 43 seconds from the last time, but there is no logical explanation yet.
Composition of the planet Mercury
The planet Mercury, like light gases, consists of a series of heavy elements, most notably iron, as it represents about 75% of its diameter, and they evaporate, and this evaporation is a result of the high temperature. This made the planet appear small in size and dense.
The density of Mercury is very close to the density of the planet, and its inner iron core is covered with a volcanic rock crust about 600 km in diameter, and the surface features of the planet are similar to the moon, since it contains many craters. Scientists and astronomers said that the cause was the collision of meteorites on the planet. as soon as it happens.
This is in addition to the volcanoes in space in the past, and it should be noted that the craters are named after famous worlds, for example: Beethoven, Shakespeare, Mark Twain and others, and this planet has a separate basin called. “Caloris” extends at a distance of 1,350 kilometers, and is one of the most important features on Mercury, as it is surrounded by several chains, and this planet lacks a protective cover.

What is the size of the planet Mercury?
Among the information that you do not know about the planet Mercury! It is known as the smallest planet in the solar system, and it is a rocky planet and has no moons, and Venus is the only planet next to Mercury, and the planet cannot absorb heat. It gets hotter and higher as it gets to about 840°F (450°C), but in the evenings it gets to 275°F (-170°C).
The planet contains 38% of Earth’s gravity, and this makes the planet unable to maintain the atmosphere of the planet’s atmosphere due to its instability and its ability to lower the temperature, so we see that the planet’s temperature is very high. Day, but very low in the evening.
Does Mercury have a magnetic field?
The planet Mercury has a magnetic field, and this is a wonderful discovery for astronomers, because magnetic fields are generated in one state where the planets rotate at full speed and also have a melting core. The planet takes 59 days to revolve around it, so it is a very small planet because its size was estimated to be about a third. This region related to the planet Mercury is very active.
The planet Mercury has an outer shell and not a large atmosphere, and this cover is a very thin and thin envelope that emanates from its surface and consists of atoms resulting from solar radiation, solar winds and the impacts of meteorites.
And after countless many studies by NASA, Mercury’s atmosphere is completely bound to the surface of the planet and is 42 percent oxygen, 22 percent hydrogen, 29 percent sodium, 0.5 percent potassium and 6 percent helium, some argon, water, carbon dioxide, Oils with nitrogen, neon and krypton.
What is the distance of the planet Mercury from the sun?
Information you did not know about Mercury
Until astronomers reached the rivalry between Mercury and the sun in detail, many studies were conducted to explore the distance between each of the planets and the sun, but on average it was 57,909,175 km, and the closest distance between the sun and the sun. The planet: 46,000,000 km, and the farthest distance is 69,820,000 km.
Mercury is one of the most densely populated planets after Earth, as it contains a very large metallic core between 2,200 and 2,400 miles (3,600 to 3,800 km) wide, and scientists have found it to be equal. 75 percent of its diameter is about 400 miles (500 to 600 km) in the outer Egypt brief. Mercury is among the rocky planets with a hard, pitted surface, and it also has a soft, gentle atmosphere.
