Are there other comets like hally (periodic phenomena's?)
I'm sure Sir Edmund Halley would prefer his surname to be spelt correctly and capitalised
there are many many periodic comets from periods of a ~ 10 years to many 10's of years
Lol excuse me and thanks
No probs :)
back to your original question, was there a particular reason for it ?
ie. are you interested in knowing what other comets you may see in a telescope?
or were you just curious ?
if the first... then doing a google search on periodic comets will yield sites with lists of them
their orbital periods, when they last were visible and when they will next be visible.
Separate names with a comma.
