Why is Mars not suitable for human habitation? How many satellites does Mars have?

The atmosphere of Mars is mainly carbon dioxide, and there is no stable liquid water. According to observational evidence, Mars has been observed to have a phenomenon similar to groundwater gushing out. How many satellites does Mars have? Why is Mars not suitable for human habitation? Let's learn about it together with Encyclopedia Knowledge Network today, I hope it will be helpful to you.

Why Mars is not suitable for human habitation

The main reason is that Mars cannot meet the standards of a suitable living environment for humans. Due to the thin atmosphere on Mars, a large amount of ultraviolet rays can directly irradiate the surface of Mars, the daily temperature is often below zero degrees Celsius, there is almost no oxygen supply, and there is a lack of food resources needed by humans.

Mars is the fourth closest planet to the Sun and the second smallest planet in size after Mercury. It is also one of the four terrestrial planets in the solar system.

In the area of ​​Mars that is exposed to the sun, the temperature difference between the perihelion and the aphelion is nearly 160 degrees Celsius.

How many satellites does Mars have?

Mars has two satellites, one is called Phobos and the other is called Deimos. Phobos and Deimos orbit almost in the equatorial plane of Mars. Phobos is about 9,450 kilometers from the center of Mars, and Deimos is about 23,500 kilometers from the center of Mars.

Phobos and Deimos are relatively close to Mars. Phobos and Deimos are only 9,000 kilometers and 23,000 kilometers away from Mars. However, because Phobos and Deimos are relatively small, with diameters only one percent of the moon, they cannot produce the visual effect of looking at the moon from the earth.

Why Mars is suitable for colonization

Some conditions on Mars are similar to those on Earth. Mars has water and an atmosphere, which can meet the basic conditions for human survival on Mars. In addition, the distance between Mars and the Earth, the distance between Mars and the Sun, and the size of Mars are very suitable, making Mars' gravity, air, and temperature very suitable for human habitation.

Mars is the fourth planet from the Sun, the second smallest planet in the solar system after Mercury, and one of the four terrestrial planets in the solar system.

The atmosphere of Mars is mainly composed of carbon dioxide and there is no stable liquid water. According to observational evidence, phenomena similar to groundwater outflows have been observed on Mars.

The orange-red appearance of Mars is because the surface is covered with hematite (iron oxide). The diameter of Mars is about half that of the Earth, and its axial inclination and rotation period are similar to those of the Earth.
