Sagittarius a Star: A Radio Source

Sagittarius A star is the black hole at Sagittarius A, which is the radio emitter. And so there's a huge black hole there, almost 5 million solar masses that the densest part of the galaxy. The whole blob near the center is very, very dense with stars. There's like 10 million stars in the sort of central cubic parsec. How dense is that? Like if we were there, would it just be toast? Would it be super bright? Could you survive? Could there be like an earth there? Or would itJust be too intense? It would be really intense.
