Walking on the Moon

Return of the comet Encke


Recommended Posts

The periodic comet 2P/Encke imaged in January 23, 2017 returns to inner Solar System in present apparition with perihelion in next March. The comet has already fired its gassy emission making a coma that reach some 6'  of angular diameter in this image (350.000 Km in absolute terms) and with an intense green color wich point to a strong emission of diatomic carbon. The tail will belate a pair of weeks in begin its development, when the comet will start to be observable with binoculars.

Thank you! It's a very good image. Love the green gassy emission. I wonder how it would smell. Never wondered that before!

I think they don't smell very well...

As comets have cyanogen in them - especially their tails - it would likely smell like almonds. C2N2 is the simplest form of the well-known group of molecules commonly called 'cyanides.' And cyanides smell like almonds or bitter-almonds.

Inhaling cyanide gas is rather inadvisable. It's what was used in gas-chambers. That's hydrogen cyanide though, but cyanogen is known to smell about the same. I've worked with cyanides in laboratories, and can confirm they usually have this odor.
