Asterisms – Mini Coat Hanger

By: Steve Goldberg  (Posted 9/13/2019)

Asterism: a grouping of stars that form a recognizable pattern.
Constellation: Ursa Minor
Right Ascension:  16h 29m 37.9s
Declination: +80° 16' 19"
Magnitude: 9 to 11
Size:  20’ 
This month’s asterism is the “Mini Coat Hanger”. The more famous “Coat Hanger” is in Vulpecula, a nice binocular or low power asterism. The “Mini Coat Hanger” is just that, a mini version.





The asterism located just off a line from Zeta ζ Ursa Minor, a corner star in the bowl, and Epsilon ε Ursa Minor, the first bright star in the handle.








In this medium power eyepiece you can definitely see how the “mini” coat hanger resembles the “major” coat hanger.


Doing a Google search for “Mini Coat Hanger”, the first in the list points to our own Guidestar article from May, 2017, written by the Guidestar Editor, Bill Pellerin. The link is: https://www.astronomyhouston.org/newsletters/guidestar/shallow-sky-object-month-mini-coathanger
