what's an orbit?

Answer 1

An orbit is a controlled fall. To reach orbital speed you must be traveling so fast that when you fall toward the earth, you follow the curvature of the earth beneath you. In that way, if there is nothing like air to slow you down, you will just continue to fall and follow the earth's curvature until you either speed up to go further out into space or slow down to fall back to earth.

Answer 2

An orbit is the movement or motion of an object in space around another, usually larger, object in space.
It is the path an object makes around another object while under the influence of a force such as gravity.

Satellites orbit the Earth, so does the moon.
The Earth orbits the sun, and so do all the other planets, asteroids, and comets.

Answer 3

Orbit is a path in which a body moves.
Ex: Earth moves around the sun in elliptical path, so Earth's orbit will make an Ellipsce.

1. the curved path, usually elliptical, described by a planet, satellite, spaceship, etc., around a celestial body, as the sun.
