what is the temperature of a comet
The comet itself has been compared to a rubber ducky due to its shape. Temperatures of the comet taken in mid-July by the Rosetta's visible, infrared and thermal imaging spectrometer â nicknamed VIRTIS for short â show that the average surface temperature is minus 94 degrees Fahrenheit (minus 70 degrees Celsius).[ Photos: Europe's Rosetta Comet Mission in Pictures ].y Elizabeth Howell, Space.com Contributor | August 14, 2014 05:30pm ET. The first temperature measurements of comet 67P/ChuryumovâGerasimenko were made between July 21 and 31, 2014, when Rosetta closed in from 14,000 kilometers to the comet to just over 5,000 kilometers.
