[nb 1] Earth's orbital speed averages 29.78 km/s (19 mi/s; 107,208 km/h; 66,616 mph), which is fast enough to cover the planet's diameter in 7 minutes and the distance to the Moon in 4 hours. [3] The point towards which the Earth in its solar orbit is directed at any given instant is known as the "apex of the Earth's way". [4] [5]
In The Martian, by Andy Weir, the spaceship Hermes uses a constant thrust ion engine to transport astronauts between Earth and Mars. In Project Hail Mary, also by Weir, the protagonist's spaceship uses a constant 1.5 g acceleration spin drive to travel between the Solar System, Tau Ceti and 40 Eridani.

The moon will soon have a companion in Earth's orbit for a limited time. ... full revolution lasting a few months, weeks or even days, ... Earth at a range around 2.8 million miles (4.5 million km ...
Earth's movement along its nearly circular orbit while it is rotating once around its axis requires that Earth rotate slightly more than once relative to the fixed stars before the mean Sun can pass overhead again, even though it rotates only once (360°) relative to the mean Sun. [n 5] Multiplying the value in rad/s by Earth's equatorial ...
In November, the sun's gravity will pull it back into an orbit around the sun — but not that far from Earth. On January 8, 2025, according to NASA, it will skim past Earth at a distance of about ...
The orbital distance of Earth will increase to at most 150% of its current value (that is, 1.5 AU (220 million km; 140 million mi)). [ 17 ] The most rapid part of the Sun's expansion into a red giant will occur during the final stages, when the Sun will be about 12 billion years old.
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 ...
