Constellation knowledge: Which is bigger, Mars or Earth?

Mars and the earth belong to eight planets. They have some similarities, but there are still gaps between them. They are different in size and quality. Then let's reveal which is bigger, Mars or Earth, according to the knowledge of constellations. Let's see the answer!

Q: Which is more important, Mars or Earth? The earth is bigger.

Mars is one of the nine planets in the solar system. Besides Venus, Mars is closest to the Earth. Mars is only 55.758 million kilometers away from the earth. Compared with the earth, its mass is less than 1/9 of that of the earth, and its radius is only about 1/2 of that of radius of the earth. But Mars is similar to Earth in many ways.

Mars is the only earth-like planet that can be clearly seen with a telescope. Through a telescope, Mars looks like an orange ball. With the change of seasons, white polar caps will appear in the North and South Poles, and some areas with alternating light and shade and sometimes changing shapes can be seen on the surface of Mars. Space exploration shows that there are still traces of the great flood on Mars. Scientists speculate that Mars is warmer and wetter than it is now, and may have once had life.

The radius of Mars is 3,397 kilometers, the radius of the earth is 6,356.755 kilometers, the mass of Mars is 6.41910.20 tons, and the mass of the earth is 5.9742 ×10.21ton.

The radius of Mars is about half that of the Earth, its volume is 15%, its mass is 1 1%, its surface area is equivalent to the land area of the Earth, and its density is much less than that of the other three terrestrial planets (Earth, Venus and Mercury). From the perspective of radius, mass and surface gravity, Mars is about halfway between the Earth and the Moon: the radius of Mars is about twice that of the Moon and half that 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.

The diameter of Mars is 6794km, and the diameter of the earth is 12756km. Mars is smaller than the earth.

Mars is the fourth planet in the solar system from the inside out, belonging to the earth-like planet, with a diameter of about 53% of the earth. Due to the axial tilt, the rotation period is similar to that of the earth, and one circle is about twice that of the earth.

Mars is basically a desert planet with sand dunes and gravel on its surface and no stable liquid water body (not long ago, NASA announced that there is a small amount of water on Mars). The atmosphere dominated by carbon dioxide is thin and cold, and dust is suspended in it, and dust storms often occur every year. The polar caps composed of water ice and dry ice at the poles of Mars will fluctuate with the seasons.

Compared with the earth, the geological activities of Mars are relatively inactive. Most of the surface landforms were formed in ancient times, with dense craters, volcanoes and canyons, including Mount Olympus, the highest peak in the solar system, and Mariner Canyon, the largest canyon. Another unique topographical 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.
