Halleys Comet is the best-known of the short-period comets, and is visible from Earth every 75 to 76 years |
|
|
Halley is the only short-period comet that is clearly visible to the naked eye, and thus, the only naked-eye comet that might appear twice in a human lifetime |
|
|
Other naked-eye comets may be brighter and more spectacular, but will appear only once in thousands of years |
