How big is the area of Mars, equivalent to several pairs of balls?

Unknown area, diameter: 6794km. Its diameter is about 53% of the earth's and its mass is 14% of the earth's. 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.

The orange appearance is the surface hematite (iron oxide). In ancient books in China, Mars was called "the twinkling star", while in ancient western countries (ancient Rome) it was called "the mythical star of Mars". It is the only guardian star of Aries in the twelve constellations, not the guardian planet of Scorpio.

Extended data:

Mars, like the earth, has a variety of topography, including mountains, plains and canyons. Mars is basically a desert planet with sand dunes and gravel on its surface. Because of the small gravity and other factors, the terrain size is different from that of the earth.

The topography of the northern and southern hemispheres is in sharp contrast: the northern part is a low plain full of lava, and the southern part is an ancient highland full of craters, which are separated by obvious slopes; Volcanic terrain is interspersed among them, and many canyons are also distributed all over the world. There are polar caps composed of dry ice (solid carbon dioxide) and water ice in the north and south poles, and aeolian sand dunes are also widely distributed all over the earth.
