Comets in solar system

Comet discovered in 2016

With the last two comets discovered in the last two months of 2016, C/2016U1 (NEOWISE) and C72016X1 (Lemmon), the total number of comet discovered in 2016 is 36 plus 1 comet discovered on STEREO images(I didn’t count the SOHO comet because they are not officially numbered at the moment). The C/2016 U1 became in the last days of the year a binocular object in the morning sky.

 

About the statistical analysis, the PanSTARRRS survey was the most prolific comet survey with 20 comet discoveries, while only one comet was discovered by an amateur astronomer, C/2016R3 by G.Borisov from Russia.

C/1729 P1 (Sarabat) - unlucky comet of the millennium

 A comet that is very much overlooked because it was by no means a spectacular visual sight , nor was it a comet with great brightness or a tail that tore the very heavens asunder, but is an object that has always perplexed me and ignited my imagination since the days of C/1995 O1 (Hale-Bopp) for one reason, its sheer size and what could have been great potential had circumstances prevailed.
