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.
Analysis of planetary surfaces and surface features is a major component of planetary science. Planetary science (or more rarely, planetology) is the scientific study of planets (including Earth), celestial bodies (such as moons, asteroids, comets) and planetary systems (in particular those of the Solar System) and
There is a broad range of things that can fall into this category. Previous examples include laboratories such as the Mars Science Laboratory, sampling techniques, the Mars rovers, the Titan lander , and submersibles. [4] Autonomous systems are preferred because data can be collected without the presence of humans near the test area.
Astronomy is a natural science that studies celestial objects and the phenomena that occur in the cosmos. It uses mathematics, physics, and chemistry in order to explain their origin and their overall evolution. Objects of interest include planets, moons, stars, nebulae, galaxies, meteoroids, asteroids, and comets.
The future of space exploration involves both telescopic and physical explorations of space by robotic spacecraft and human spaceflight. Near-term physical exploration missions, focused on obtaining new information about the Solar System , are planned and announced by both national and private organisations.
Kepler-1638b was thought to be a possibly habitable planet with a radius smaller than 2 R 🜨 after the validation. However based on the later measurement of host star parallax by Gaia, the radius of the planet was revised upward to 3.226 +0.201 −0.315 R 🜨, resulting in it being a ice giant like Neptune with poor prospect for habitability ...

Mars is an example of a planet in the OHZ.: it is just beyond the HZ today, but had liquid water for a short time span before the Mars carbonate catastrophe, some 4 billion years ago. [ 26 ] [ 27 ] Continuously habitable zone (CHZ): a zone where liquid water persists on the surface of a planet for years.
