Although not commonly photographed, Sh2-216 (aka Simeis 288) is a fascinating object. Sh2-216 is not only the closest planetary nebula to us, it also appears as the largest planetary nebula in our sky. With an apparent diameter of 1.6 degrees, the nebula is over 3 times the diameter of the full Moon. Its large size in our sky is due to its close proximity - its only about 420 light years from our solar system.

As a planetary nebula, Sh2-216 represents one way that stars can die - it is the remains of shells of gases that a star throws off in its dying stages. A planetary nebula leaves behind a relatively small, dense and hot star known as a white dwarf.

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.
