When an item has been launched into orbit, what happens?

1: It continues to fall but its path never reaches the ground.

2: Centripetal force from Earth's gravity keeps it from being accelerated toward Earth.

3: It no longer falls because the weakness of Earth's gravity with increased height has made it lighter than air.

4: It no longer falls because it is outside the atmosphere.

5: It is kept in orbit by attraction to the sun and moon.
