Object info
Comet 17P/Holmes is a periodic comet which was discovered by Edwin Holmes in 1892. In October 2007, this comet experienced a dramatic increase in brightness from magnitude 17 to about 2.8 (becoming an easy naked eye object). This increase represents an increase in brightness of a factor of about 500.000 times.
By November the comet's coma had grown to a size larger than the diameter of our Sun ! (in the sky)
