One complete orbit takes 365.256 days (1 sidereal year), during which time Earth has traveled 940 million km (584 million mi). [2] Ignoring the influence of other Solar System bodies, Earth's orbit , also called Earth's revolution , is an ellipse with the Earth–Sun barycenter as one focus with a current eccentricity of 0.0167.

This plot shows a ship capable of 1-g (10 m/s 2 or about 1.0 ly/y 2) "felt" or proper acceleration [6] can travel vast distances, although is limited by the mass of any propellant it carries. A spaceship using significant constant acceleration will approach the speed of light over interstellar distances, so special relativity effects including ...

The asteroid was discovered in August and is set to become a mini-moon, spinning around Earth in a horseshoe shape for about two months. Earth will get a second moon for nearly 57 days this year ...
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]
A clock used to time a full rotation of the Earth will measure the day to be approximately an extra 10 ns/day longer for every km of altitude above the reference geoid." [ 35 ] Travel to regions of space where extreme gravitational time dilation is taking place, such as near (but not beyond the event horizon of) a black hole , could yield time ...
