We show a live comet countdown timer under our banner that counts down to the next passing of a specific comet that you have chosen.
You can choose a new comet to count down from the drop down box/list and the timer will automatically update the countdown and the "More information" link.
The "More information" link can be used to find more comet specific information for the comet you have selected.
If you are looking for something more specific use the search box.
We have an multiple independently sourced archive of comet information.
