In 2021, evidence for a probable impact 3.46 billion-years ago at Pilbara Craton has been found in the form of a 150 kilometres (93 mi) crater created by the impact of a 10 kilometres (6.2 mi) asteroid (named "The Apex Asteroid") into the sea at a depth of 2.5 kilometres (1.6 mi) (near the site of Marble Bar, Western Australia).

Earth in a few billion years could likely resemble present Venus. One billion years from now, about 27% of the modern ocean will have been subducted into the mantle. If this process were allowed to continue uninterrupted, it would reach an equilibrium state where 65% of the current surface reservoir would remain at the surface. [58]
The meteorite, S2, was first discovered in 2014. It hit the planet about 3.26 billion years ago and is estimated to have been up to 200 times larger than the space rock that later killed the ...
This is a list of asteroids that have impacted Earth after discovery and orbit calculation that predicted the impact in advance. As of December 2024 [update] , all of the asteroids with predicted impacts were under 5 m (16 ft) in size that were discovered just hours before impact, and burned up in the atmosphere as meteors .
In September Nasa’s Osiris-Rex safely brought samples from asteroid Bennu to Earth. 4.5 billion-year-old asteroid could reveal the origins of life on Earth Skip to main content
A piece of an asteroid has arrived on Earth from the other side of the solar system, in a major success for Nasa’s Osiris-Rex mission. ... Since Bennu is around 4.5 billion years old, the sample ...
The Earth will naturally become uninhabitable due to the Sun's stellar evolution, within about a billion years. [147] In around 1 billion years from now, the Sun's brightness may increase as a result of a shortage of hydrogen, and the heating of its outer layers may cause the Earth's oceans to evaporate, leaving only minor forms of life.

NASA revealed Wednesday that newly returned samples from a 4.5-billion-year-old asteroid contain traces of carbon and water — molecules that are thought to make up the building blocks of life.
