Mars vs. Sun , which is better?

Mars is the fourth planet from the Sun and the second-smallest planet in the Solar System after Mercury.

The Sun is the star at the center of the Solar System. It is a nearly perfect sphere of hot plasma, with internal convective motion that generates a magnetic field via a dynamo process.
