Radiation from a Charged Black Hole Orbiting a Planet

If I had a charged black hole and it was orbiting a planet, would it radiate just like a point charge?

I don't think point charges radiate due to acceleration by gravity.

isn't that what everyone was worried about until quantum theory. about why the electron doesn't just radiate away its energy and fall into the nucleus.

If I had a charged black hole and it was orbiting a planet, would it radiate just like a point charge?

It might be better to say "just like an object with the same mass and electric charge and that's not a black hole". If that's what you mean, then the answer is "yes, at least at sufficient distances from the planet and its charged satellite".

With that said, you might want to take a moment to consider the frequency and the intensity of that radiation... It's not very exciting stuff, at least not compared with an electron "orbiting" a nucleus.

it seems like the black hole would also radiate
