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 60,000 years (57,617 BC). The record minimum distance between Earth and Mars in 2729 will stand at 55.65 million km.
Mars's average distance from the Sun is roughly 230 million km (143 million mi), and its orbital period is 687 (Earth) days. The solar day (or sol ) on Mars is only slightly longer than an Earth day: 24 hours, 39 minutes, and 35.244 seconds. [ 185 ]
Earth and Moon transiting the Sun in 2084, as seen from Mars. Image created using SpaceEngine Earth and Moon from Mars, as photographed by the Mars Global Surveyor. A transit of Earth across the Sun as seen from Mars takes place when the planet Earth passes directly between the Sun and Mars, obscuring a small part of the Sun's disc for an observer on Mars.
The Hubble Space Telescope (HST) has been used to perform systematic studies of Mars [91] and has taken the highest resolution images of Mars ever captured from Earth. [92] This telescope can produce useful images of the planet when it is at an angular distance of at least 50° from the Sun.
Did you know Mars is named after the Roman god of war?
Mars Global Surveyor imaged the Earth and Moon on May 8, 2003, 13:00 UTC, very close to maximum angular elongation from the Sun and at a distance of 0.930 AU from Mars. The apparent magnitudes were given as −2.5 and +0.9. [8] At different times the actual magnitudes will vary considerably depending on distance and the phases of the Earth and ...
On 21 March 1963, when the spacecraft was at a distance of 106,760,000 km from Earth, on its way to Mars, communications ceased due to failure of its antenna orientation system. [44] [45] In 1964, both Soviet probe launches, of Zond 1964A on June 4, and Zond 2 on November 30, (part of the Zond program), resulted in failures. Zond 1964A had a ...
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 2021, oscillating around L 4 in a tadpole orbit and expected to remain there for at least 4000 ...
