Orbit of Mars relative to the orbits of inner Solar System planets Orbit of Mars and other Inner Solar System planets An animation to explain the (apparent) retrograde motion of Mars, using actual 2020 planet positions Mars seen through a 16-inch amateur telescope, at 2020 opposition. Mars has an orbit with a semimajor axis of 1.524 ...
Mars is at its brightest when it is in opposition, which occurs approximately every twenty-five months. Jupiter and Saturn are the largest of the five planets, but are farther from the Sun, and therefore receive less sunlight. Nonetheless, Jupiter is often the next brightest object in the sky after Venus.
The variation of Mars's axial tilt is much larger than for Earth because it lacks the stabilizing influence of a large moon like Earth's Moon. Mars has a 124,000-year obliquity cycle compared to 41,000 years for Earth.

Apparent retrograde motion of Mars in 2003 as seen from Earth The term retrograde is from the Latin word retrogradus – "backward-step", the affix retro- meaning "backwards" and gradus "step". Retrograde is most commonly an adjective used to describe the path of a planet as it travels through the night sky, with respect to the zodiac , stars ...
Mars during the 1999 opposition as seen by space telescope Mars at its 2018 opposition, with its atmosphere clouded by a global dust storm that snuffed out the solar-powered Opportunity rover The James Webb Space Telescope captured its first images and spectra of Mars on 5 September 2022.
The closest in the past 1,000 years was in 1761, when Mars and Jupiter appeared to the naked eye as a single bright object, according to Giorgini. Looking ahead, the year 2348 will be almost as close.
Seen from a superior planet, an inferior planet on the opposite side of the Sun is in superior conjunction with the Sun. An inferior conjunction occurs when the two planets align on the same side of the Sun. At inferior conjunction, the superior planet is "in opposition" to the Sun as seen from the inferior planet (see the diagram).
