178P/Hug–Bell is a periodic comet in the Solar System. It was discovered by Northeast Kansas Amateur Astronomers' League members Gary Hug and Graham Bell and is thought to be the first periodic comet to be discovered by amateurs. It was declared a comet less than two days after its initial discovery, after having its course confirmed on previous images.[4]

orbit of Jupiter. Because it never comes closer to the Sun than about 2 AU, it is never expected to be a very bright comet, with a typical perihelion magnitude of 18–19.[5]
