The north pole is farther from the sun than the equator. So when the temperature is 30 C at the equator its way below zero in the north pole. But Mars is more farther from the earth but still sometimes the temperature goes above zero. Why?

Is it uniform all over Mars? I doubt. May be the portion facing sun experiencing a higher temperature. What ever may be the answer, the question is a good one

Because all three planets (Venus, Earth, and Mars) are in whats called the "Life Zone". They are all a distance from the sun when they could each support life IF the atmosphere was right. Venus is too hot due to a real thick atmosphere that traps in all the heat and mars has a very thin atmosphere (almost none) so it does not hold any heat in. (or block harmful radiation) Earth is just right. If we could create the perfect atmosphere on the other two planets we could also live there. (An almost impossible task at this point in human evolution.) Mars DID have water before. (It's now been proven.) We also think it might have had an atmosphere before losing it long ago. The size is another factor. The smaller the size the less the Gravity to hold it around the planet. Hope this answers your question and hope you pick my answer as the winner.

Orbital eccentricity relates the shape of the path of Mars' orbit around the Sun. A circle has an eccentricity of zero, and a larger number means it is more elliptic. Orbital inclination is the tilt of the planet's orbit in relation to the ecliptic plane .Earth's orbit defines the ecliptic plane. Mars approaches nearest to Earth every two years and two months.
Mars has 4 seasons, just like the Earth. They are, namely, spring, summer, autumn and winter. This is because of its axial tilt and sicne Mars' tilt is similar to that of Earth, so are its seasons. As Mars takes more time to revolve around the Sun, its seasons are nearly twice as long as that of Earth's. Temperatures can be very extreme on Mars ranging from -225°F in autumn and winter to 65°F in spring and summer. But sometimes it may reach earth's temperature due to its closeness to sun than north pole.
