NGC 5466 bei Mondlicht

---------------------------------

NGC 5466 ist ein Kugelsternhaufen im Sternbild Bärenhüter. NGC 5466 hat einen Durchmesser von 9,2' und eine scheinbare Helligkeit von +9,1 mag. NGC 5466 gehört zum Halo der Milchstraße und ist sowohl vom Sonnensystem als auch vom Zentrum unserer Galaxis rund 55.000 Lichtjahre entfernt. Er enthält außergewöhnlich geringe Mengen an schweren Elementen, was auf ein sehr hohes Alter hindeutet.

NGC 5466 gehört zur niedrigsten Konzentrationsklasse XII, mit geschätzten 100.000 Sonnenmassen zählt er zu den masseärmsten bekannten Kugelsternhaufen. Nur seiner Bahn, die ihn in genügend großem Abstand vom galaktischen Zentrum fernhält, hat es dieser lose gebundene Sternhaufen zu verdanken, dass er über Milliarden von Jahren hinweg noch nicht völlig von den Gezeitenkräften aufgelöst wurde (Wikipedia).

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
