Usher in the New Year with Comet Catalina

By Mario Carr

If you’ve received a pair of binoculars for Christmas, you could see Comet Catalina just before dawn in the south eastern morning sky.

Catalina will appear higher in the sky each night and will be above the handle of the Big Dipper passing near galaxy M101 on January 16. The next night, on January 17, Catalina will make its closets approach to the Earth at 108 million kilometres. After that date, the comet will fade rapidly each night.

The comet is thought to be a first time visitor around the Sun arriving form the distant Ort cloud beyond the realm of Pluto. After its brief encounter near the Sun, it will be flung out of our solar system never to return again.

Also known as C/2013 US10, the comet was discovered on Halloween night in 2013 at the Catalina Observatory near Tucson, while searching for asteroids.

Here are January stargazer events. Most are listed in the Hamilton Amateur Astronomers calendar, which is currently on sale.
