The Earth formed over 4.6 billion years ago out of a mixture of dust and gas around the young sun. It grew larger thanks to countless collisions between dust particles, asteroids, and other growing ...

Earth is believed to have formed partly from carbonaceous meteorites, which are thought to come from outer main-belt asteroids. Telescopic observations of outer main-belt asteroids suggest that they ...

Around 4.6 billion years ago, a young, hot star was born. The Sun formed from a cloud of gas and dust, and over time planetary bodies, including Earth and Mars, came to be. It’s unlikely that ...
