Where is comet Holmes located?

constellation of Perseus
Comet 17P/Holmes is currently in the constellation of Perseus. The current Right Ascension is 04h 45m 34s and the Declination is +42° 17′ 41”. 17P/Holmes is above the horizon from Greenwich, United Kingdom [change]. Given its current magnitude, 17P/Holmes is visible only through long exposure photography.

How often can Comet Holmes be seen?

every 7 years

What makes Halley’s Comet unique?

Halley is the only known short-period comet that is regularly visible to the naked eye from Earth, and thus the only naked-eye comet that can appear twice in a human lifetime.

Will Earth ever be hit by a comet?

NASA knows of no asteroid or comet currently on a collision course with Earth, so the probability of a major collision is quite small. In fact, as best as we can tell, no large object is likely to strike the Earth any time in the next several hundred years.

During its 2007 return, Holmes unexpectedly brightened from a magnitude of about 17 to about 2.8 in a period of only 42 hours, making it visible to the naked eye. This represents a change of brightness by a factor of about half a million and is the largest known outburst by a comet.
