Un amas d’étoiles sur qui on peut compter !

NGC2169 est un jeune amas ouvert situé dans la constellation d'Orion. Il a été découvert par l'astronome germano-britannique William Herschel en 1782. Il est aussi possible que l'astronome sicilien Giovanni Battista Hodierna ait observé cet amas avant 1654.
Il se situe à environ 3.430 années-lumière du système solaire et les dernières estimations donnent un âge de 11,7 millions d'années. Sa taille est d'environ 6,0 années-lumière et il renferme moins de 50 étoiles.
Selon la classification des amas ouverts de Robert Trumpler, cet amas renferme une trentaine d’étoiles.

La disposition de certaines de ses étoiles suggère, en surnom populaire, un nombre : le 37 (voir version annotée). Il est aussi appelé l’amas du Chariot de Course ou les Petites Pléiades. On peut le trouver facilement au-dessus de Bételgeuse, juste entre les deux petites étoiles.

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.
