Mars is on fire.
Mars is the fourth planet in the solar system from the inside out.
Mars is about half the diameter of the earth, with a volume of 15% and a mass of 1 1%. Its surface area is equivalent to the land area of the earth, but its density is far less than that of the other three terrestrial planets (Mercury, Venus and Earth). In terms of radius, mass and surface gravity, Mars is about halfway between the earth and the moon. Mars is about twice the diameter of the moon and half the diameter of the earth. Its mass is about 9 times that of the moon and19 of the earth, and its surface gravity is about 2.5 times that of the moon and 2/5 of that of the earth.
Mars is the fourth planet in the solar system from the inside out (the first three are Mercury, Venus and Earth respectively), belonging to the Earth-like planet, with a diameter of about half that of the Earth. It takes twice as long to rotate obliquely from the axial direction with a similar rotation period. The West calls it Mars Mythology Star, God of War and China call it Fluorescent Star, because it is as bright as fire, and its position and brightness often change. Its orange-red appearance is because the surface is covered with hematite (iron oxide), and the prefix areo- is Mars in English. Mars was once considered to be the most likely planet in the solar system to have extraterrestrial life.
Mars is basically a desert planet, with sand dunes and gravel all over the surface and no stable liquid water body. The atmosphere dominated by carbon dioxide is thin and cold, and dust is suspended in it, and dust storms often occur every year. Compared with the earth, the geological activity is inactive, and another unique topographic feature is the obvious difference between the northern and southern hemispheres: the southern part is an ancient highland covered with craters, while the northern part is a younger plain. Both poles of Mars have polar caps mainly composed of water and ice, and the dry ice covered on them will fluctuate with the seasons.
The distance from Mars to the Earth
The shortest distance is about 55 million kilometers and the longest distance is over 400 million kilometers. Close contact between them occurs about once every 15 years. In 1988, the distance between Mars and the earth once reached about 58.8 million kilometers, but in 20 18, the distance between them will reach 57.6 million kilometers. But on August 27th, 2003, the distance between Mars and the Earth was only about 55.76 million kilometers, the latest time in 60,000 years.
