Can a celestial object orbit a black hole?
In effect, millions of near and far celestial objects might be orbiting a Black Hole.
It is a scientific hypothesis that the Milky Way (MW) galaxy is centered around a Black Hole. Every star system in the MW, including our Sun system, orbits this galactic center.

It is true that a celestial object can orbit a black hole; in fact, a large number of stars have been observed to do so, forming what is known as a binary system.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
