Comete C/2014E2

C/2014E2

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 just a keen eye and a decent pair of binoculars.

This picture (right), taken by astrophotographer Damian Peach, shows Comet Jacques just days after discovery on March 16th, its coma already clearly visible.

Comet Jacques reached perihelion (its closest point to the Sun) on July 3rd 2014, passing Venus ten days later at a fairly close 7.9 million miles (12.7 million kilometres).

At the end of this month, on August 29th, the comet will be at its closest to Earth at 52,432,000 miles (84.4m kilometres).
