Our moon is a particularly unusual example of moons when it comes to planetary bodies. Though many other planets in the solar system have moons, they are very different from our own. Most planets have ...

A collision between Earth and a massive Mars-sized protoplanet likely caused the formation of our moon. Now scientists from the Max Planck Institute suggest that doomed planet was likely a rowdy ...

The asteroid 2024 YR4, which was once thought to be on a collision course with Earth, may still pose a threat to the planet. There is still a chance the space rock could smash into the moon, and the ...

the Earth you walk on today might not be the same planet that was born 4.5 billion years ago. Many scientists believe that in its infancy, Earth collided with another world the size of Mars, and that ...

Stars passing close to the sun could cause planets to collide, including with Earth, or even be ejected as rogue planets, new simulations show. By Katherine Kornei If our species manages to hang on ...

New research suggests that Theia, the object whose collision with Earth is theorized to have caused the formation of the moon, came from closer to the sun. Artist’s impression of the collision between ...

The asteroid known as 2024 YR4 is out of sight yet still very much on scientists’ minds. The building-sized object, which initially appeared to be on a potential collision course with Earth, is ...

Roughly four and a half billion years ago the planet Theia slammed into Earth, destroying Theia, melting large fractions of Earth’s mantle and ejecting a huge debris disk that later formed the moon.

Earth is so far the only known planet on which life exists—with liquid water and a stable atmosphere. However, the conditions were not conducive to life when it formed. The gas-dust cloud from which ...

Scientists have shown that Earth’s basic chemistry solidified within just three million years of the Solar System’s formation. Initially, the planet was barren and inhospitable, missing water and ...
