Messier 35 (M 35)

On this page I collect my observations of the open star cluster M 35 in the constellation Gemini/Twins.



I did not know the Gemini/Twins constellation for a long time, but a friend pointed me to Castor and Pollux, a pair of stars, which can be easily found at the nightly sky. The older form of the Gemini constellation reminds me of a jug lying on its side. I can therefore remember this and use it as an aid for finding the open star cluster M 35, which is supposed to be visible even to the naked eye. M 35 is, however, located on opposite (open) side of the jug (on the right) above the last star of the constellation (which somewhat "turns upwards" = the "spout"). Read more on how to find the cluster below.

M 35 is said to be the open star cluster with the most stars in winter.

May 2017: M 35 above the right upper end of constellation Gemini/Twins. At this time of the year, it was turned to the right for nearly 90 Grad, so that M 35 was located at the bottom right of the constellation. (Image Courtesy of SkySafari Astronomy,
