Expert Answer:

if the body is thrown directly above then it will fall down after reaching a certain height but if it is prjected in a horizontal direction, then it will reach a certain height, and will orbit around the earth for sometime before falling down. (thats how sattelites are launched in space, all of them are not compeletely out of earth's gravitational pull)
