How far is the event horizon from a black hole?

The Basics There is simply a region, or boundary, in space around a black hole beyond which we cannot see. This boundary is called the event horizon. The radius of the event horizon (proportional to the mass) is very small, only 30 kilometers for a non-spinning black hole with the mass of 10 Suns.

How far away do you have to be from a black hole?

We’re not sure how the universe makes supermassive black holes, though. Albert Einstein rejected the idea that black holes might exist. The closest known black hole, called 1A 0620-00, is 3,000 light- years away. For comparison, our nearest stellar neighbor is 4.2 light-years away.

What happens when you get too close to a black hole?

The exact effects depend on the size and mass of the black hole. That is the same effect that creates the tides on Earth: the gravitational pull on the side of the object that is closest to the black hole is significantly stronger than the pull on the opposite side, so gravity stretches the object and pulls it apart.

Can you survive Spaghettification?

This bending and stretching is called spaghettification. Someone outside the black hole would see your body begin to stretch and bend like a spaghetti noodle. As you approach the edge of the event horizon, you will freeze in space and time. Additionally, once you reach the event horizon, you may survive.

How close can you get to a black hole?

You would have to be careful to perpendicular to the black hole, so that the stretching is along the small distance across the body instead of the large distance from head to toe. So with that universal-record-holding black hole, that would occur at a distance of seven million kilometers. That would be about as close as you could go. Dec 6, 2011

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.

How dangerous is it to orbit a black hole?

There’s a large black hole much closer to us at the center of our galaxy (~50,000 Light years away), but we are orbiting that one and there’s no danger posed by that black hole. Right, but for a massive black hole, you get way inside the event horizon before you feel tidal forces. Are you safe before this?

What happens if you fall into a black hole feet first?

In other words, if the person is falling feet first, as they approach the event horizon of a stellar mass black hole, the gravitational pull on their feet will be exponentially larger compared to the black hole’s tug on their head.
