MARS
Explanation:
Mars represents the 4th planet of the solar system, being next to the earth. It is comprised of a hard and solid surface and the average surface temperature of Mars is extremely cold, which is roughly about -60°C. The atmosphere of Mars is very thin, which is dominantly comprised of CO₂ gas (almost 95%), along with some molecular Nitrogen (3%) as well as there is the presence of Argon (2%). In addition to this, it is also composed of dust clouds within its atmosphere. There is the absence of a magnetic field in Mars, due to which the solar wind highly affects the atmosphere of Mars.
