Comet Catalina on January 21, 2016, captured from the shared telescopes of Slooh.com by Don Wahl.
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!

I don’t have a tracker for my camera, so it’s been difficult to expose the comet without it just looking like a star trail. I finally had better luck this morning!” Thanks, Sara!

Greg Hogan caught the comet on December 16, 2015. He wrote: “Hey, wanted to share an unexpected surprise. I was imaging Catalina this morning and when I reviewed the shots, I noticed something in the image, turns out it is a galaxy!” In fact, it’s the galaxy NGC 5496. Thanks, Greg!
Abhinav Singhai in India caught this photo on December 14, 2015. He wrote: “Single shot of Comet Catalina along with Venus and a meteor, on Gemind meteor shower night, over Sariska Palace, Rajasthan.” Visit Abhinav Singhai on Flickr.

View larger. | Greg Hogan in Kathleen, Georgia caught this photo on December 7, 2015. He wrote: “So what are the odds? I was going through the images from Dec 7th and noticed that in one of the shots there was two meteors! One was the tail end of a bright one, and one is faint. I saw some large bright ones that morning but was not sure if they were in the frame. It seems part of one was.”
View larger. | Greg Hogan also created this awesome composite image of the December 7 moon, Venus and Comet Catalina. Greg told EarthSky: “I did one short exposure to expose for the moon. I then merged the two images to over lap to get the lunar details. I used a Canon 7D on a EQ Mount for tracking. I stacked the image in DEEP SKY STACKER and balanced the exposures using Lightroom 4.” This photo was the Astronomy Picture of the Day for December 12, 2015. Congrats, Greg!
