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 ...
Artist's rendering of NASA's 2001 Mars Odyssey orbiting Mars. The following table is a list of Mars orbiters, consisting of space probes which were launched from Earth and are currently orbiting Mars. As of August 2023, there have been 18 spacecraft missions operating in Mars' orbit, 7 of which are currently active.

The length of time for Mars to complete one orbit around the Sun in respect to the stars, its sidereal year, is about 686.98 Earth solar days (≈ 1.88 Earth years), or 668.5991 sols. Because of the eccentricity of Mars' orbit, the seasons are not of equal length.
Mars is the fourth planet from the Sun.The surface of Mars is orange-red because it is covered in iron(III) oxide dust, giving it the nickname "the Red Planet". [22] [23] Mars is among the brightest objects in Earth's sky, and its high-contrast albedo features have made it a common subject for telescope viewing.
NASA released a stunning image on Friday showing our home planet as well as the moon from Mars.
The Moon and Mars on August 27, 2005, showing Mars to be much smaller. The Mars hoax was a hoax circulated by e-mail that began in 2003, that claimed that Mars would look as large as the full Moon to the naked eye on August 27, 2003. The hoax has since resurfaced each time before Mars is at its closest to Earth, about every 26 months. It began ...
