Object name: NGC0659

Designation(s): NGC0659,

NGC 659 is an open cluster in Cassiopeia. The WEBDA says it is about 6,300 light-years away though many internet sources say it about 10,000 to 11,400 light-years away without giving a source. Its diameter is about 5 minutes of arc which translates to a diameter of about 15 to 17 light-years using the larger distance, 9 light-years using the 6,300 figure. The cluster's age is difficult to pin down but it is likely about 112 million years old. For more on this see:
