When Comet C/2013 US10 (Catalina) emerged into our predawn sky in November, many hoped it would become visible to the eye. It did not do so, but Comet Catalina has still been a fascinating object, an icy visitor from the Oort comet cloud and a great target for photographers. So enjoy these images of this cosmic visitor, taken by members of the EarthSky community. And know that – before entering the realm of the planets – Comet Catalina is thought to have had an orbit around our sun of several million years. It rounded the sun on November 15, 2015 and began heading outward again. The trajectory of this visitor from the Oort cloud suggests it will be ejected from the solar system, and we will never see this comet again. Our thanks to all who posted!
