NGC 2174 est une nébuleuse en émission située dans la constellation d'Orion. NGC 2174 est aussi appelée nébuleuse de la Tête de Singe. Elle a été découverte par l'astronome allemand Karl Christian Bruhns en 1857. Il est probable que cette nébuleuse ait été observée par l'astronome sicilien Giovanni Battista Hodierna avant l'an 1654.

NGC 2175 est un très jeune amas ouvert4,3 situé dans la constellation d'Orion. Il a été découvert par l'astronome français Édouard Stephan en 18771.

NGC 2175 est à environ 1 627 pc (∼5 310 a.l.) du système solaire et les dernières estimations donnent un âge de 9,0 millions d'années. La taille apparente de l'amas est de 18 minutes d'arc, ce qui, compte tenu de la distance, donne une taille réelle maximale d'environ 28 années-lumière.

Selon la classification des amas ouverts de Robert Trumpler, cet amas renferme moins de 50 étoiles (lettre p) dont la concentration est faible (IV) et dont les magnitudes se répartissent sur un grand intervalle (le chiffre 3).

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.
