Yeah Mars is freezing But if you consider other Places in the Universe like Triton, Sedna, Pluto, Eris and Kuiper Belt objects you realise Mars is just cold. And if you consider the Jupiter Type Planets that get thrown out of their Solar Systems by passing Hot Jupiters. Did you know that Parts of Mercury are colder than mars because Mercury is so close to the sun its year is 88 Earth Days and it is locked in synchronus rotation so one side sees the sun at full volume and is very hot but the part that gets no Sunlight ever is -180c and Mercury is the Closest Planet to the sun.
