Welcome to LIVE Comet Data


We display real-time information on some of the more notable comets zooming around our solar system. The comets listed here are usually of high interest to the astronomical community, this might be because they’ll appear brighter or come closer than most other comets, or even (like in the case of Comet 67P Churyumov–Gerasimenko), the European Space Agency have sent their Rosetta Spacecraft to orbit and deploy a Lander (Philae) to the comet’s surface.



Popular Comets

Comet 67P (Churyumov-Gerasimenko)

Comet Churyumov-Gerasimenko (67P) will be the focus of the Rosetta spacecraft mission over the next year and a half. Rosetta has now arrived at the comet and, after scanning the comet for a suitable landing site this month, will deploy a lander (Philae) to the comet’s surface this coming November.


Comet Jacques (C/2014 E2)

Discovered only in March of this year, Comet Jacques (C/2014 E2) was predicted to be one of the brighter comets of 2014. Although, still fairly faint, Comet Jacques reached a magnitude of +5.66 last month and was visible with a keen eye and a decent pair of binoculars. See LIVE data including Right Ascension and Declination data here.


Comet Siding Spring (C/2012 A1)

Discovered in January of last year, it was quickly established that Comet Siding Spring was going to pass ‘very’ close to Mars on 19th October this year. The latest calculations show Siding Spring passing Mars at a distance of just 84,000 miles above the planet’s surface!

Comet Siding Spring's Path

At just one third the distance of our Moon, Comet Siding Spring (C/2012 A1) is set to pass Mars ten times closer than any recorded comet has ever passed Earth. As NASA currently have two spacecraft orbiting the red planet (and one on the way), cautionary measures are being drafted to manoeuvre the spacecraft (if necessary) out of harms way …more >
