Neptune's moon Triton falls through the planet's Roche limit, potentially disintegrating into a planetary ring system similar to Saturn's. [107] 4.5 billion Mars reaches the same solar flux as that of the Earth when it first formed 4.5 billion years ago from today. [92] < 5 billion
The biological and geological future of Earth can be extrapolated based on the estimated effects of several long-term influences. These include the chemistry at Earth 's surface, the cooling rate of the planet's interior , gravitational interactions with other objects in the Solar System , and a steady increase in the Sun's luminosity .
Considering the future possibility of extended, crewed missions, food storage and resupply are relevant limitations. From a storage point of view, NASA estimates a 3-year Mars mission would require around 24 thousand pounds (11 t) of food, most of it in the form of precooked, dehydrated meals of about 1.5 pounds (0.68 kg) a portion.

The footprints left in the lunar dust by astronauts are perhaps the most emblematic of humanity’s ongoing journey, which will likely include planets like Mars in the future, the researchers said.
Dwarf planet 90377 Sedna will reach its perihelion of 76 AU from the Sun. [34] 2079 August 11 Mercury occults Mars, the first since at least 1708. [31] 2083 A star system known as "V Sagittae" is expected to go nova this year (+/- 11 years). 2084 November 10 Transit of Earth as seen from Mars, the first and the only one in this century. 2085 ...
Planetary habitability in the Solar System is the study that searches the possible existence of past or present extraterrestrial life in those celestial bodies. As exoplanets are too far away and can only be studied by indirect means, the celestial bodies in the Solar System allow for a much more detailed study: direct telescope observation, space probes, rovers and even human spaceflight.
Near-Earth asteroids have orbits that approach relatively close to Earth's orbit, [136] and some of them are potentially hazardous objects because they might collide with Earth in the future. [137] [138] Mars-crossing asteroids are those with perhihelia above 1.3 AU which cross the orbit of Mars. [139]
According to evidence found in 2015, it is the largest ever recorded. [70] A third, possible impact was also identified in 2015 to the north, on the upper Diamantina River , also believed to have been caused by an asteroid 10 km across about 300 million years ago, but further studies are needed to establish that this crustal anomaly was indeed ...
