In about 65 billion years, it is estimated that the Moon may collide with the Earth, due to the remaining energy of the Earth–Moon system being sapped by the remnant Sun, causing the Moon to slowly move inwards toward the Earth. [109] Beyond this point, the ultimate fate of the Earth (if it survives) depends on what happens.
The Earth and Moon are very likely destroyed by falling into the Sun, just before the Sun reaches the top of its red giant phase. [112] [note 3] Before the final collision, the Moon possibly spirals below Earth's Roche limit, breaking into a ring of debris, most of which falls to the Earth's surface. [114]
Before the final collision, the Moon possibly spirals below Earth's Roche limit, breaking into a ring of debris, most of which falls to Earth's surface. [215] [216] 22 billion Various The end of the Universe in the Big Rip scenario, assuming a model of dark energy with w = −1.5.
An asteroid called 2020 CD3 was bound to Earth for several years before leaving the planet's orbit in 2020 and another called 2022 NX1 became a mini-moon of Earth in 1981 and 2022 and will return ...
Earth will soon have a second moon, but it will be nothing like the one we're accustomed to seeing in the night sky. The new "mini-moon" will be asteroid 2024 PT5, a space rock discovered earlier ...
For about two months, Earth had a temporary second moon from an asteroid that scientists believe originated from our only Moon.
Without the Moon the axial tilt of Earth could therefore oscillate chaotically from 0° to 45° on the scale of tens of thousands of years, possibly reaching 85° on timescales of several million years, [11] with severe climatic consequences. [9] [4] [6] More recent studies however suggested that, even without the Moon, Earth's axial tilt could ...
Earth has a new “mini-moon” after an asteroid has joined our orbit. The object, known as 2024 PT5, has been chasing after us for years. Now, it has become close enough to be pulled in by our ...
