Main Question or Discussion Point
I understand that there are a few of these still out there that have basically become Earth-crossing asteroids. It would seem that they wouldn't be as bright as the recent Chelyabinsk meteor.
A technical correction, if it hit the Earth it wouldn't be bright.How bright of a bolide would a Saturn IV-B stage be if it hit Earth
hard to say, maybe just as bright but not for as long a timeIt would seem that they wouldn't be as bright as the recent Chelyabinsk meteor.
Ah, I should have taken that into account. It wouldn't be much at all - perhaps not even strong enough to be a bolide. And of course, Skylab was about the same sizeNot by my reckoning. The mass of the meteorite )Wikipedia) is estimated at 14,000 tons. The empty mass of the S IVB is less than 15 tons . .....
