NGC 2217

This object is a nearly face-on lenticular ring galaxy located 80 million light years away in the constellation of Canis Major at a declination of -27 degrees. This 11.9 magnitude galaxy spans 4.5 arc-minutes in our apparent view, which corresponds to a diameter of 105,000 light years. This galaxy is classified as a lenticular galaxy because of the lack of spiral arm structure in the central galaxy region.

This galaxy has a fascinating structure with many different features - a bright core, a tight bright ring around the core, an ansae bar (bar with "handles" or bright enhancements at each end), and a faint wider ring (including a star stream on the left side). Scientists believe that ring structures typically result from a collision of a compact galaxy with a larger spiral galaxy.

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.
