The other planets gravitationally “tug” on the planet Mars’ orbit and change the shape. The gas giant, Jupiter is especially influential on Mars’ orbit. The Earth and Mars don’t lie in the same plane from an orbiting perspective. Planets take a slightly tilted path around the Sun in ...

are quite different. Compared to Earth, a year on Mars lasts almost twice as long – 686.98 Earth days. This is due to the fact that Mars is significantly farther from the Sun and its orbital period (the time it takes to orbit the Sun) is significantly greater than that of Earth’s....
In terms of their orbits, Earth and Mars are also quite different. For instance, Earth orbits the Sun at anaverage distance (aka. semi-major axis) of 149,598,261 km – or one Astronomical Unit (AU). This orbit has a very minor eccentricity (approx. 0.0167), which means its orbit ran...

experiences periodic changes at intervals similar to those between ice ages on Earth. Calculations indicate that the causes are probably also similar: the gravitational pull of the other planets produces variations in Mars’ orbit and tilt as the great clockwork of the solar system goes through its...
In the 1960s, humans set out to discover what the red planet has to teach us. Now, NASA is hoping to land the first humans on Mars by the 2030s.
