The orbit of Mars around the Sun is elliptical, taking about 687 Earth days to complete one full revolution. This longer orbital period is due to its greater distance from the Sun compared to Earth. Mars orbits at an average distance of about 227.9 million kilometers (141.6 million miles). Mars has a tilt of about 25 degrees, similar to Earth, which results in seasonal changes. Its orbit is also more eccentric than Earth's, meaning that the distance from the Sun varies significantly throughout the year. This affects the planet's climate and temperature variations.
