If Earth is not ejected during a stellar encounter, then its orbit will decay via gravitational radiation until it collides with the Sun in 10 20 (100 quintillion) years. [109] If proton decay can occur and Earth is ejected to intergalactic space, then it will last around 10 38 (100 undecillion) years before evaporating into radiation. [110]
The estimated time for Earth to naturally replenish its fossil fuel reserves. [63] 80 million The Big Island will have become the last of the current Hawaiian Islands to sink beneath the surface of the ocean, while a more recently formed chain of "new Hawaiian Islands" will then have emerged in their place. [64] 100 million [note 1]
The first eon in Earth's history, the Hadean, begins with the Earth's formation and is followed by the Archean eon at 3.8 Ga. [2]: 145 The oldest rocks found on Earth date to about 4.0 Ga, and the oldest detrital zircon crystals in rocks to about 4.4 Ga, [34] [35] [36] soon after the formation of the Earth's crust and the Earth
Earth's expected long-term future is tied to that of the Sun. Over the next 1.1 billion years, ... This last phenomenon is the greenhouse effect: ...
With its 80,000-year orbit, the celestial body would have been last seen from Earth at the time of the Neanderthals. The Virtual Telescope Project in Italy captured images of the comet from May ...
Precessional movement of Earth. Earth rotates (white arrows) once a day around its rotational axis (red); this axis itself rotates slowly (white circle), completing a rotation in approximately 26,000 years [1] In astronomy, axial precession is a gravity-induced, slow, and continuous change in the orientation of an astronomical body's rotational ...
O f the eight planets and 293 moons that call our solar system home, only Earth has a surface that sloshes with liquid water. Roughly 71% of the face of our world is covered in seas, lakes, rivers ...
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 ...
