does the sun have an orbit  away from a black hole?

If you have a powerful telescope, you are able to discover that most stars are in pairs, and each star of the pair moves around a common point. There is a possibility that our sun has another star as its companion, spinning around a point. So, it is not necessary to have an orbit away from a black hole.

In order not enter into an orbit around the Sun, the planetoid would have to be going very fast.  This would mean it would also be going fast enough not to be captured by Earth's gravity.\n\nSo assuming it then passes very close - say as close as the moon - it would raise some tidal forces. But they would be very short lived and so probably not noticeable (the sea tides are noticeable because they are repeated every day and set up resonances that are much larger than the day to day tide - they also set up points of zero tide called amphidromic points).\n\nThere is no prospect of it changing land masses without actually hitting the Earth. It would also be far less likely than the moon to cause any geological disturbance.\n\nThere is no reason at all that a planetoid would set up any sort of EMF.

Like all gravitationally-formed objects, a black hole is roughly spherical in shape (like planets and stars, a rotating black hole will be slightly flattened at the poles.)  According to Hawking's theory, black holes do emit radiation (and therefore mass) in accordance with quantum rules.  Theoretically, given enough time a black hole could radiate away enough of its mass to disappear completely.  When its mass drops below a certain critical threshhold, the remaining mass of the black hole would disappear in a final violent burst of gamma radiation.  Unfortunately (or perhaps fortunately) the best estimates we have for the time it would take for a black hole to explode in this way is far longer than the current estimated age of the universe, so it is not likely we would be able to test this theory through direct observation.

No, the speed of light in vacuum is constant everywhere.\nLight follows the path of minimum energy (geodesics) in gravitational fields, which are bent around the masses.\n\nThe amount of bending at the surface of the sun is of the order of arc seconds. However close to a black hole the bending is so strong, that the light path bends around and around the hole, never to escape.

No more than the earth does work orbiting the sun. An orbit has constant energy, and if it is not circular, there is a continuous process of exchanging kinetic energy with potential energy while the sum stays the same.

Why would you think that the sun does NOT move? \n\nThe sun moves in many ways. It rotates on its axis; different latitudes of the sun move at different rates, as can be observed with sunspots. The sun moves in its orbit around the barycenter of the solar system, which can be quite far removed from the sun's center. The sun's surface oscillates in different modes, similar to the ringing of a bell that has been struck by a hammer. The surface of the sun moves, and we observe solar prominences and other phenomena. The sun's surface will eventually expand as it changes character and becomes much larger as it moves through its lifespan. The entire solar system is moving through our galaxy at a tremendous speed, and our galaxy is moving as well very rapidly.\n\n\nI might also note that for vamsee, the answerer below, it is true that the distance from the earth to the sun is slowly increasing, but this is better attributed to tidal effects than the Big Bang:\n\nhttp://curious.astro.cornell.edu/question.php?number=317

Nobody has found any evidence for a form of gravity the repels instead of attracting, but that doesn't keep people from looking for it. It may yet be found. But such a force is not needed to explain orbital motion. In fact, it would disrupt orbits, causing the Earth to fly away from the Sun and never return.

A black hole is an object predicted by general relativity with a gravitational field so strong that nothing can escape it — not even light.\n\nA black hole is defined to be a region of space-time where escape to the outside universe is impossible. The boundary of this region is a surface called the event horizon. This surface is not physical, just an imaginary boundary. Nothing can move from inside the event horizon to the outside, even briefly.\n\nThe existence of black holes in the universe is well supported by astronomical observation, particularly from studying X-ray emission from X-ray binaries and active galactic nuclei. It has also been hypothesized that black holes radiate energy due to quantum mechanical effects known as Hawking radiation. \n\nHistory\n\nThe concept of a body so massive that even light could not escape was put forward by the English geologist John Michell in a 1784 paper sent to the Royal Society. At that time, the Newtonian theory of gravity and the concept of escape velocity were well known. Michell computed that a body with 500 times the radius of the Sun and of the same density would have, at its surface, an escape velocity equal to the speed of light, and therefore would be invisible. In his words:

Yes. but for it to stop then the Sun would first have to disappear as it is its gravitational pull which is causing the Earth to orbit at such speed. So there is probably more chance of you winning the lottery every day for the rest of your life than the sun doing a vanishing act.

Yes, but not in our lifetime.  The orbit is 1,500 years from our sun to a dead sun outside our solar system.  We have a better chance of meeting helpful space visitors than planet X.

When the Sun has Sunspots you can see that they revolve around the Sun.\n\nIt basically rotates similar to how the planets rotate.\n\nRotate not orbit.

Black holes don't have a purpose they just are!\n\nHowever Wikipedia gives\n\nA black hole is a concentration of mass great enough that the force of gravity prevents anything past its event horizon from escaping it except through quantum tunnelling behaviour (known as Hawking Radiation). The gravitational field is so strong that the escape velocity past its event horizon exceeds the speed of light. This implies that nothing, not even light, inside the event horizon can escape its gravity. It is, however, theorized that wormholes can let one exit a black hole. The term "black hole" is widespread, even though it does not refer to a hole in the usual sense, but rather a region of space from which nothing can return.\n\nThe existence of black holes in the universe is well supported by astronomical observation, particularly from studying X-ray emission from X-ray binaries and active galactic nuclei.

The realistic answer is no, for several reasons.  \n1)  Our sun is too small to collapse into a blackhole.  Even if it did the planets are too far away to be sucked in.  Just because a star turns into a black hole doesn't mean that its gravity get any stronger.  The planets would just orbit it like normal except that there would be no light coming out of it and also no heat.  \n\n2) Our galaxy spirals around a black hole and we haven't been sucked in yet.  Once again, that is because a black hole is only as strong as the mass it contains.  Instead it just keeps all of the stars in the galaxy orbiting around it.  \n\n3) They only way it is possible is if one of the minor galaxies which orbits our galaxy happened to collide with the Milky Way.  If that were to happen the black hole in that galaxy could pass near enogh to the Earth or our solar system to suck us in.

The motions and orbits of all the major bodies in our solar system have been analyzed and found to be consistent with their masses. In other words, the masses involved in our solar system explain the observed orbits of all major bodies. If a black hole was around, its gravity would help cause orbits other than what we see. Not only that, but material sucked into a black hole is acclerated to near light speed which causes it to generate immense amounts of radiation. No such phenomenon is present in our solar system.

No, because a black hole is a collapsed star, and the closest star to us, besides the sun, is thousands of light years away. They also suck in EVERYTHING including light and destroys it.

Earth is revolving in orbit, held in place by the Sun's gravitational pull

Thats correct, merely a song. A sun couldnt esist in a black hole. It would be ripped to shreads in seconds!
