Can a planet survive near a black hole?

So planets could potentially form around black holes, but that’s no guarantee that they offer a life-friendly environment. On Earth, living things are hugely dependent on the light and warmth from the Sun to survive. Without the glow of a star, life around a black hole would likely need an alternative source of energy.

How close can you get to a black hole without being sucked in?

The Schwarzschild radius defines the size of a black hole’s event horizon, a boundary beyond which you wouldn’t be affected by a black hole, as long as you stay on the opposite side of it. The closest you could get to a black hole, without being sucked in, would be two times the Schwarzschild radius.

Is it possible to orbit a black hole without falling?

It is possible to be near a black hole without falling into it, provided you move rapidly. This is similar to what happens in the solar system: Earth does not fall into the Sun because we move around it at a speed of some 67 thousand miles per hour.

What happens if a planet gets too close to a black hole?

The edge of the Earth closest to the black hole would feel a much stronger force than the far side. As such, the doom of the entire planet would be at hand. We would be pulled apart.

Do any planets orbit black holes?

For a black hole with the same mass as our Sun, the required speed is the same as that needed to orbit at the same distance from our parent star. Whether any planets really do orbit black holes is a different matter, however. The chances of any planet remaining intact through such a cataclysmic event seem pretty slim.

Will humans ever leave our galaxy?

The technology required to travel between galaxies is far beyond humanity’s present capabilities, and currently only the subject of speculation, hypothesis, and science fiction. However, theoretically speaking, there is nothing to conclusively indicate that intergalactic travel is impossible.

Could a planet orbit around a black hole?

Black holes are typically thought of as destructive forces… but could they allow a planet to orbit without causing harm? There’s no fundamental reason why not: despite their reputation for devouring anything that goes into them, black holes are really just another source of gravity – like a star.

How did planets survive the destruction of their parent star?

Quite how they survived the destruction of their parent star is something of a mystery. One possibility is that they were formed after the supernova, from the debris created by the explosion. So despite the odds, it may just be possible that there are black holes out there with planets orbiting them.

Why don’t black holes eat anything?

There’s no fundamental reason why not: despite their reputation for devouring anything that goes into them, black holes are really just another source of gravity – like a star. As such, they’ll cheerfully allow anything to orbit them if it travels fast enough.
