I’ve wondered if ANYTHING man made, other than rockets have left earths grasp. I.E. Can a bullet be fired fast enough, or a jet with A/F mixture climb fast enough to leave earths gravity and never return? Why or why not is this possible? TY

Fritz Zwicky's "artificial meteors" might count. Though they were launched from a rocket, it wasn't a rocket capable of reaching orbit; the pellets were launched away from the rocket by an explosive after it reached the upper atmosphere.

It's believed that they escaped earth's gravity well and went into orbit around the sun. There's no real confirmation that they did, but it's certainly possible.
