How to use this page

Choose your place and a night at the top. The page shows where the object is in the sky, when it is best placed, how bright it should be and how its brightness and distance change over the coming months. The values come from its orbit as published by NASA JPL.

Frequently asked questions

How bright will it be?

The page gives the brightness predicted from JPL’s standard formulas. Comets often brighten or fade faster than predicted, so treat the value as a guide.

Can I see it without a telescope?

Only when it is brighter than about magnitude 6 and the sky is dark. Most comets and asteroids need binoculars or a telescope.

How accurate is the position?

Positions are worked out from JPL’s orbital elements and are accurate for weeks to months around the date of those elements, which are refreshed daily.
