Would a black hole the size of an average asteroid "glow"

[From: ] [author: ] [Date: 11-11-26] [Hit: ]
Europa, has a mass of about 1.65×10^19 kg; a black hole with that mass would have a temperature of 7740 K (13,470 F).Smaller black holes would be even hotter.Yes,......
Let's say an average sized asteroid was compressed to become a black hole, would such a black hole "glow"?

The temperature of a black hole is T = 1.277 x 10^23 K kg / mass. The 6th largest asteroid, Europa, has a mass of about 1.65×10^19 kg; a black hole with that mass would have a temperature of 7740 K (13,470 F). Smaller black holes would be even hotter.

Yes, it would definitely glow -- brighter than the Sun (5778 K).

I presume you mean emit enough hawking radiation to be observable.

Firstly, all black holes emit radiation in the form of hawking radiation, but they emit such small ammounts that it isn't visable to the human eye.

Secondly, the smaller a black hole is, the more hawking radiation it emits.

If a black hole is too small, it will not have enough gravity to hold its contents, and will subsequently explode into nothingness.

A blackhole, for example, the weight with the weight of an oil carrier would burst into radiation. Thusly no, as such a black hole would be too small to be able to hold its own weight, and no black hole can be small enough to emit enough radiation to "Glow". As it were, the heaviest possible(theoretical) black holes are microscopic, with weights compareable to mountains.
