Could a black hole be right in our solar system? how would we know its there?

Question

or would our space ships have to start mysteriously disappearing ..say on the way to Mars before we know?

Answer 1

There would be particles orbiting around the black hole. This would indicate that a black hole could exist because to travel in a circular or eliptical orbit, there needs to be some centripetal force, which would be provided by the gravity of the mass of the black hole.

Answer 2

A Black Hole most probably does exist right in the center of our Milky Way Galaxy, but not within our Solar System. While they are invisible to the eye (telescope or not) they are detectable using Radio Telescopes, and one has never been reported within our solar system.

As a result, since no space voyages outside of our solar system have been planned yet, there is not any chance that Space Ships will go missing due to Black Holes any time soon. And, of course, Mars is within our Solar system.

Answer 3

A stellar sized black hole isolated from anything it could consume would be invisible to our telescopes, but it would not approach unannounced. That is because it would cause spacecraft and the planets too to start drifting off their designated course or their orbits. Moreover, the spacecraft and planets nearest to the black hole would be affected the most. A mini black hole, say the mass of an asteroid might sneak by undetected from the pull of it's gravity, but their Hawking radiation would be detected by satellites and space probes. If the black hole has a mass similar to Jupiter, it would wreak havoc upon the Solar system like a stellar mass black hole would, but not until it's much closer. A stellar mass black hole can disrupt our Solar System and still remain far beyond Neptune's orbit around the Sun.

Answer 4

It depends on how massive the black hole was. If it somehow just appeared in our solar system without any warning, the first thing we'd notice would be a super-intense blaze of x-radiation as everything near the hole was sucked in at near the speed of light. If we had time, we'd later on notice that the orbits of all or some of the planets were changing very quickly. If it was a mini-blackhole about all we'd notice would be that intense source of x-radiation and, depending where the hole was located in our system, some planet orbital parameters might change to some degree.

Answer 5

Perhaps in our galaxy...NOT in our solar system. One in our solar system would have sucked in the Sun, or enough of its' light at least, that we would have noticed. We notice the gravitic effects of tiny basketball sized asteroids on the light from our sun. A black holes' gravitic effect would be noticeable long before a space ship got close enough to disappear. No such effects noticed means no black hole present.

Answer 6

Well since black holes warps space, and light warps with it, then you might see a significant distortion of the light by stars and the sun, as well as the reflected light of a planet. That is one way how scientist have been able to confirm the existence of black holes in space.

Answer 7

They think there is a black hole in the center of our galaxy but you will never know anything about it by traveling to mars because it is a good many light years away from us,,

Answer 8

No. A black hole in our Solar System would have caused a chaos and we wouldn´t be surfing the internet by now.

Answer 9

The accretion disk would be obvious.

The radiation from matter falling in to it would be obvious.

Its gravity would perturb the orbits of the planets.

Answer 10

We'd definitely see if a black hole were in our galaxy
