- It is called as Red Planet because of the effect of the iron oxide prevalent on Mars’s surface, which gives it a reddish appearance distinctive among the astronomical bodies visible to the naked eye.
- The days and seasons are comparable to those of Earth, because the rotational period as well as the tilt of the rotational axis relative to the ecliptic plane are similar.

- Mars is approximately half the diameter of Earth, with a surface area only slightly less than the total area of Earth’s dry land.
