What does earth revolution mean?

Answer 1

With regard to astronomical objects, 'revolution' normally means one body's

process of traveling in a gravitational orbit around another one.

Examples:

-- revolution of the planets, including the Earth, around the sun

-- revolution of the natural satellites, including Earth's moon, around their respective planets

-- revolution of the artificial satellites, including the International Space Station and the

TV, GPS, and weather satellites, around the Earth

Answer 2

Revolution is the period a planet takes to orbit around the Sun or star. It is what we call a year.

A moon will revolve it's parent planet. Our Sun - and the Solar System, revolve around the galactic centre.

Not to be confused with rotation, which is the period a moon, planet or star takes to "spin" once on it's axis.

Answer 3

"Revolation" isn't a word (at least, it's not an English word), so I'm going to try to guess what you might have meant.

The Earth both revolves (around the Sun, with a period of about 365.25 days) and rotates (around its own axis of rotation, with a period of about 23 hours 56 minutes relative to the distant stars or 24 hours exactly with respect to the Sun). It also precesses (changes its axial tilt) with a period of about 23,000 years, and there are some other smaller motions.

Answer 4

It means it turns around another object. The Earth moves (revolves) around the Sun, and the Solar system, including Earth and Sun, move around the center of the Milky Way.
