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. [110] 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. [111]
It has since been set backward 8 times and forward 17 times. The farthest time from midnight was 17 minutes in 1991, and the nearest is 90 seconds, set in January 2023.
