Prograde Orbit
Prograde orbit is an orbit in which a satellite or a spacecraft moves in the same direction as the rotation of the planet. In other words, the satellite moves from west to east in the same direction as the planet's rotation. This type of orbit is preferred for most space missions because it requires less fuel to achieve and maintain the orbit. Prograde orbits are commonly used for Earth observation, communication, and navigation satellites, as well as for missions to the Moon and other planets. The opposite of a prograde orbit is a retrograde orbit, in which the satellite moves in the opposite direction of the planet's rotation.
