Over millions of years, these objects grew larger, sweeping up material in their orbits and becoming the planets we know today. This model of solar system formation is known as the nebular hypothesis.

With the exception of Pluto, planets in our solar system are classified as either terrestrial (Earth-like) or Jovian (Jupiter-like) planets. Terrestrial planets include Mercury, Venus, Earth ...

Swirling around that fireball were particles that gathered into spherical clumps, whose gravitational fields attracted smaller clumps, and so on, eventually creating the four terrestrial planets ...

Astronomers have discovered that "super-Earth" planets may exist on wider orbits than previously thought — and this implies these rocky, or "terrestrial," worlds are far more common than was ...

We have developed a state-of-the-art atmospheric climate-biogeochemical model for terrestrial planets (1D-TERRA) with photochemistry and unique air-shower physics. We are international leaders in ...

Our research interests have been primarily in understanding the physical processes that control the evolution of terrestrial planets (Earth, Moon, Mars, ...). Modern space exploration has provided ...

Most terrestrial planets have atmospheres, but the conditions on their surfaces would not allow humans to survive there. Venus is the hottest planet in our solar system (despite being further from ...

"The two main questions we wanted to answer were how many species of terrestrial animals there are on the planet and how quickly do new species of terrestrial animals evolve." Terrestrial animals ...
