C/2022 E3 (ZTF) est une comète à longue période qui a été découverte par le Zwicky Transient Facility le 2 mars 2022.
Elle a atteint son périhélie le 12 janvier 2023, à une distance de 1,11 Unité Astronomique, et sa position la plus proche de la Terre le 1er février 2023, à une distance de 0,28 UA.
On s'attendait à ce que la comète devienne plus brillante que la magnitude 6 tandis que sa magnitude absolue est estimée à 10,5 au début de février 2023.
Il s'agit d'une comète ordinaire du nuage de Oort, laquelle avait dû y rester durant plusieurs milliards d'années.
C/2022 E3 (ZTF) a été découverte par les astronomes Bryce Bolin et Frank Masci à l'aide du Zwicky Transient Facility (ZTF) dont Masci était le directeur le 2 mars 2022.
Début novembre 2022, la comète avait atteint la magnitude 10. Celle-ci présentait à ce moment-là une chevelure de couleur verte, une queue de poussière jaunâtre et une faible queue ionisée.
En février 2023, la position apparente de la comète dans le ciel se rapproche de celle de plusieurs objets très lumineux : d'abord, Capella du 6 février, puis le 11 février la planète Mars, elle-même proche des Pléiades et enfin, le 15 février, C/2022 E3 et l'étoile Aldébaran.

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.
