In approx 7 billion years because the expanding Sun will swallow planet earth in about 8 billion years, by then all of the air & water should be pumped underground & humanity will be living underground on planet earth because if water & air remained on the surface of the earth it would evapourate out into space due to the heat of the expanding sun. It will take 6.24x10^17 Megatons of TNT to move the earth out of its orbit.
Orbit
If Earth moved slower in its orbit around the Sun, its orbit would be elongated and the duration of a year would increase. This could lead to changes in climate patterns and potentially affect the length of seasons. However, the overall impact would depend on how much slower Earth's orbital speed becomes.
The earthquake in Japan has moved the earth 25 centimeters(cm) and shortened the day by 1.8microseconds.
It takes about 27.3 days for the Moon to orbit the Earth exactly one time. During that orbit, however, the Earth has moved 27.3 days along in its own orbit around the Sun, so the time between "new moons" is 29.5 days.
Earth's rotation should eventually be synchronized with the Moon's orbit.
An earth orbit that is lower to earth then both a medium and high earth orbit.
The planets do not orbit the Earth, they orbit the sun.
The moon is in its first quarter phase. It's moved about a quarter of the way around its orbit since the new moon. The sun, moon, and Earth form a right angle (90 degrees) during this phase, causing half of the moon facing Earth to be lit up and the other half to be dark.
The moon orbits Earth.
Anything in "orbit" is falling into the object that its orbiting ... and constantly missing. Because by the time the (orbiting) object has fallen far enough to hit ... the object it is orbiting has moved far enough so that they miss each other.
there are roughly 12.5 looner orbits to 1 orbit of the earth The moon takes 27.32 days to orbit the Earth.
High orbit, Gravity weakens as you move away from its source, and although less centripetal force is needed to maintain larger circlular paths at a given speed gravity weakens at a greater rate.
