That depends how close the star is to a supermassive black hole. And how close they can be at the closest, without getting destroyed, would depend on the mass of the supermassive black hole. There are several stars that orbit Sag A* in a few years - something around 10-15 years. However, I think it is theoretically possible for a star to get even closer, and therefore orbit in less time.For information about orbits in general, take a look at Kepler's laws, especially Kepler's Third Law.

Could a supermassive black hole swallow your solar system?
It seems unlikely that this will occur before our Milky Way galaxy collides with Andromeda. Our solar system seems to be safely in orbit around the supermassive black hole in the center of the Milky Way, but in 4 billion years, when Andromeda (with its OWN supermassive black hole) collides with the Milky Way, it might possibly happen.
Around what does the sun orbit?
Yes, most everything in the universe has an orbital path around another large body. The sun revolves around the center of the milky way galaxy, which is a supermassive black hole. Many suns revolve around black holes or other large bodies with large gravitional pulls.
The life time for supermassive black holes?
It depends on the mass of the black hole. Typical lifetimes are ten to the power 100 years.
How many light years are we from the black hole?
The supermassive black hole in the center of our Milky Way is at a distance of about 28,000 light-years. The nearest known stellar black hole is at a distance of about 3000 light-years.
How does the Suns life cycle differ from that of massive and supermassive stars?
The life cycle of a Sun-like star differs from that of massive and supermassive stars primarily in its lifespan and end state. A Sun-like star, like our Sun, has a stable life of about 10 billion years, eventually evolving into a red giant and shedding its outer layers to form a planetary nebula, leaving behind a white dwarf. In contrast, massive stars burn through their nuclear fuel much more quickly, leading to shorter lifespans of a few million years, and they end their lives in dramatic supernova explosions, potentially leaving behind neutron stars or black holes. Supermassive stars, which can be several times more massive than typical massive stars, also undergo supernova events but can create black holes with significantly larger masses, influencing their surrounding environments more profoundly.
How long is it before a massive star becomes a red supergiant?
Supermassive stars have extremely short lifespans, ranging from some 50 million years to a mere million years.
What is the most dangerous black hole?
None, really. At least, for us, and now. A black hole can be dangerous if it's very massive (such as a supermassive black hole). But mainly, a black hole would be completely harmless, unless it gets close - and the nearest known black hole is at a distance of about 3000 light-years. Even a supermassive black hole would be harmless at such a distance.
Are there any present black holes?
Yes. The nearest known black hole is about 3,000 light years away in the system V616 Monocerotis. There is a probably supermassive black hole at the center of the Galaxy, about 26,000 light years away.
What is inside the Andromeda galaxy?
The Andromeda galaxy contains billions of stars, gas, dust, and dark matter. It also has a supermassive black hole at its center, along with star clusters and nebulae. The galaxy is located about 2.537 million light years away from Earth.
Is 5 million years quite old for a black hole?
No - In fact, the Chandra X-ray Observatory detected a jet of X-rays from a supermassive black hole 12.4 billion light years from Earth.
What do black holes orbit?
No. There are no black holes in our solar system. Based on current models, the smallest stellar mass black holes are at the very least about 3 times the mass of the sun. Therefore, if there were a black hole in our solar system the sun would either orbit it or the two would orbit about a common center of mass.
What is the name for older stars?
"Main sequence" stars are no longer new, and are just cookin' along for millions of years. "Main sequence" stars, depending on their weight and whether they orbit another nearby star can get old and become red dwarfs, white dwarfs, black dwarfs, neutron stars, novas, or super-novas.
