Here's why:
* Gravity: Pulls objects towards each other. In the case of an object in orbit, gravity pulls the object towards the center of the larger body (like a planet).
* Speed: The object in orbit needs to be moving fast enough to constantly fall *around* the larger body, rather than directly into it.
Think of it like this:
Imagine throwing a ball horizontally. It will fall to the ground due to gravity. Now imagine throwing the ball harder. It will travel farther before hitting the ground. If you could throw it fast enough, it would theoretically fall all the way around the Earth and come back to you – that's an orbit!
In orbit, the object's speed is constantly balanced by the pull of gravity:
* Too slow: The object would fall directly into the larger body.
* Too fast: The object would fly off into space.
Examples of orbits:
* The Moon orbiting the Earth
* Satellites orbiting Earth
* Planets orbiting the Sun
