How close do you have to be to get sucked in a black hole?

There is no additional sucking force at all. In fact, many of the objects that would have hit Earth previously will now miss the black hole. Only the rare objects that cross the event horizon — a mere 2 cm across (as opposed to ~12,700 km for the actual Earth) — will get swallowed.

Could you get close enough to a black hole to see it?

Astronomers have found the closest black hole yet at just 1000 light years from Earth, close enough to see the stars that orbit it without a telescope. Marianne Heida at the European Southern Observatory in Germany, and her colleagues spotted this black hole completely by accident.

How far away can you see a black hole?

It’s about 30,000 light years away from us and is one of the brightest objects in the X-ray sky. CraigNASA: Can you see a black hole with a normal telescope?

Can you stay in a stable orbit around a black hole?

Just outside the black hole, but before reaching the event horizon, the gravitational forces are so extreme that stable orbits become impossible. Once you reach this region, you cannot remain in placid orbit.

What happens outside a black hole’s event horizon?

The event horizon of a black hole is the invisible line-in-the-sand across which you can never return. Once anything passes through the event horizon, even light itself, it can no longer return to the universe. The black hole’s gravity is just too strong within that region. Outside a black hole, however, everything is just dandy.

What is the temperature of a black hole?

Jerry: The black hole itself has very little temperature, but when matter is about to enter the black hole, just before it disappears, it’s heated to millions of degrees and emits X-rays. This has been observed in at least a dozen different objects in our own galaxy.
