Extra-close oppositions of Mars happen every 15 to 17 years, when we pass between Mars and the Sun around the time of its perihelion (closest point to the Sun in orbit). The minimum distance between Earth and Mars has been declining over the years, and in 2003 the minimum distance was 55.76 million km, nearer than any such encounter in almost ...
Mars 2, Mars 3 and Mariner 9 were all launched into space in May 1971, and all entered Mars’ orbit that same year. NASA's Mariner 9 reached the planet's orbit first on November 14, narrowly beating the Soviet's spacecraft amid the space race, and subsequently became the first spacecraft to orbit another planet.

A Mars cycler is an elliptical orbit (green) that crosses the orbits of Earth (blue) and Mars (red), and encounters both planets at the points where it crosses their orbits, although not necessarily on every orbit. (Not to scale.) A Mars cycler (or Earth–Mars cycler) is a kind of cycler, a spacecraft with a trajectory that encounters Earth ...
The Close Approach happens every two years, but Tuesday's encounter at 38.6 million miles away will be the closest to Earth that Mars gets until 2035
L 4 is the Sun–Earth Lagrange point located close to the Earth's orbit 60° ahead of Earth. Asteroid (706765) 2010 TK 7 is the first discovered tadpole orbit companion to Earth, orbiting L 4; like Earth, its mean distance to the Sun is about one astronomical unit. Asteroid (614689) 2020 XL 5 is the second Earth trojan, confirmed in November ...
The next close approach to Earth will be in the year 2047 at a distance of 5 million kilometers, about 13 times the distance between Earth and the Moon. [69] Simulations over a 3-million-year timespan found a probability of the Roadster colliding with Earth at approximately 6%, or with Venus at approximately 2.5%.
Up to eight Starship rockets could launch when the next Earth-Mars ... space agency pushed forward its own mission to Mars by two years. The Tianwen-3 sample return mission will now take place in ...
Seasons. Mars has an axial tilt of 25.19°, quite close to the value of 23.44° for Earth, and thus Mars has seasons of spring, summer, autumn, winter as Earth does. As on Earth, the southern and northern hemispheres have summer and winter at opposing times. However, the orbit of Mars has significantly greater eccentricity than that of Earth.
