Then at 150,000mph it might be 85 billion miles from Earth, barring any kind of drag or impact. It would have been traveling too fast to have burned up on its way out of Earth's atmosphere owing to its size (4 inches thick and 2ft across) and weight,2000lbs. Lots of smaller meteorites make it to Earth without vaporizing, through at slower speeds. This would be the first man-launched object to break orbit. Most thought it would have been vapourized, but you'd expect they'd have at least seen that
Oddly, there appears to be no pictures or motion-picture film preserved from observation of the event.

acceleration. Or the fact that the plasma fireball would have been
well ahead of it, and that's what it would have been traveling
through.
It's atoms.

It would be out of the atmosphere in 1/3 of a second. I don't believe it is long enough to completely vaporize a solid iron object. I don't know how fast the fastest meteorites have hit the atmosphere, but if they are of any size, some of them make it
