Halley’s Comet is presently a little more east, close to the brilliant star Procyon, than it was previously. That’s where it may be found in the night sky, but Halley’s Comet is not as far away as any other star, of course. It is located in what is known as the Kuiper Belt, which is the region of the Solar System beyond the orbits of Neptune and Pluto.
