Near-Earth Asteroid 2018 CC approaching the Earth: an image (06 Feb. 2018)
The near-Earth a steroid 2018 CC is safely approaching us, meantime we captured it while sharing it live with the world. Here it is an image.
Above it is an image coming from a single 120-seconds exposure, unfiltered, taken with the 16″-f/3.75 Tenagra III (“Pearl”) unit. The robotic mount tracked the fast (110″/minute) apparent motion of the asteroid, so stars are apparently trailing. The asteroid is perfectly tracked: it is the sharp dot in the center, marked with two red lines.
At the imaging time, asteroid 2018 CC, having a diameter of 13-29 meters, was about 490,000 km from us, safely coming closer. You can see it live, online!
The observatory is placed at 1300 meters above the sea level, in the Sonoran desert, providing one of the best skies in the world. This image was taken as part of the cooperation between the Virtual Telescope Project and Tenagra Observatories, Ltd.
