Abstract: The climates of terrestrial planets with a small amount of water on their surface, called land planets, are significantly different from the climates of planets having a large amount of ...

We can estimate the time since a terrestrial planet’s surface was last “reset” (e.g., globally altered, such as by lava flows) based on crater counting, but those times are not formation ages.

The thin atmosphere, or exosphere, does little to prevent or slow down impacts from extraterrestrial objects, leaving the surface littered with craters. In appearance it is similar to Earth's Moon.

Mercury has 88 days in a year and is a terrestrial planet ... multiple times and is the most explored outside of planet Earth. The surface of Mars is dry and rocky but is like Earth.

The planet orbits its host star in just 30.5 hours, losing a mass of material roughly equal to Mount Everest each time ...
