There is no official definition; often the term is attached to comets such as Halley’s Comet, which are bright enough to be noticed by casual observers who are not looking for them, and become well known outside the astronomical community.

How do comets become so spectacular?
For a comet to become spectacular, it also needs to pass close to the Earth if it is to be easily seen. Halley’s Comet, for example, is usually very bright when it passes through the inner Solar System every seventy-six years, but during its 1986 apparition, its closest approach to Earth was almost the most distant possible.
