Mars is one of the eight major planets in the solar system, the fourth planet in the solar system from inside to outside, and belongs to the Earth-like planet. It has a diameter of about 53% of the Earth, a mass of 11% of the Earth, and a surface gravity of about 2/5 of the Earth.

The inclination angle and rotation period of the axis are similar to that of the Earth. The average Martian day is 24 hours, 39 minutes, 35.244 seconds, and the revolution per week is about twice the Earth's revolution time.

The close distance is about 55 million kilometers, and the farthest distance is more than 400 million kilometers. The close contact between the two occurs approximately every 15 years.

The orange-red Mars appearance is hematite or iron oxide on the surface.

Mars is basically desert planets, with surface dunes, gravel and meteorites everywhere, and has a certain stable underground liquid water body.

Due to factors such as small gravity, the terrain size is also different from that of the earth.

The terrain of the northern and southern hemispheres has a strong contrast: the north is a lowland filled with lava, and the south is an ancient highland full of craters, and the two are separated by obvious slopes; the volcanic terrain is interspersed with many canyons, and many canyons are also distributed in various places, and the north and south poles have extreme crowns composed of dry ice and water ice, and the wind turns into sand dunes and spreads across the planet.

The atmosphere dominated by carbon dioxide is both thin and cold, with sand and dust suspended in it, and dust storms often occur every year. The extreme crowns composed of water ice and dry ice at both poles of Mars will grow and grow with the season.

Compared with the Earth, Mars is less active in geological activities, and most of the surface landforms were formed during the more active periods in ancient times. They were densely packed with craters, volcanoes and canyons, including the second highest mountain in the solar system, Olympus Mountain and the largest canyon, the Mariner Canyon.

Another topographic feature is the obvious difference between the northern and southern hemispheres: the south is an ancient, crater-filled highland, and the north is a younger plain.

Mars has two natural satellites: Phobos and Phobos, which are irregular in shape and may be isolated dwarf asteroids. On Earth, Mars can be visible to the naked eye, with the highest brightness up to -2.9, etc. Among the eight planets, they are darker than Jupiter and Venus.

Mars is called the God of War in the West, perhaps due to its bright red color, so Mars is sometimes called a "red planet".

Mars was called "Yimu" in Tianxia. This is because Mars is red and fluorescent like fire. Its brightness often changes in the five elements. Its brightness is also moving in the sky, sometimes from west to east, and sometimes from east to west. The situation is complicated and confusing. Therefore, Tianxia in ancient times called it "Yimu" which means "Fluorescent Fire, Lili and Confused".

And now it is presented to humans through ultra-high definition lenses.

Speaking of which, this is the first time that humans have logged on to live on Mars. Although this kind of live broadcast is several dozen minutes slower, for humans as a whole, this is both a live broadcast!

"Niupi, it's so spectacular!"

"Login, log in!"

"Mars, we humans are here!"

"Go and see the Martians!"
