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 ...

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 ...

Earth formed around 4.54 billion years ago. Knowing how old Earth is can be more difficult to confirm because Earth's age is not only based on the age of rocks, but also the isotopic estimates of what ...

Over 4.6 billion years ago, Earth took shape from a spinning cloud of dust and gas surrounding the young sun. Tiny particles within this cloud collided and clumped together, driven by gravity and ...

A study on the Earth's formation titled "Stochastic accretion of the Earth" has been published in the journal Nature Astronomy. Researchers from ETH Zurich have used a new modeling approach to ...

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 ...

Earth's oceans may have formed directly from the “star stuff” that coalesced into the early solar system, according to new research – challenging the idea that most of Earth’s water was delivered here ...

The leading theory for how the Moon formed was that it was the product of a catastrophic collision between Earth and another planet the size of Mars 4.5 billion years ago, known as the giant impact ...

Scientists have long debated whether the Earth's water was here when the planet formed or whether it arrived later. A study suggests much of the water originated in rocks from which Earth is built.
