Comet C/2022 E3 (ZTF)

Comet C/2022 E3 (ZTF) is a recently discovered comet that was first observed by the Zwicky Transient Facility (ZTF) on March 9, 2022. It is a long-period comet, meaning that it takes more than 200 years to orbit the sun.This particular comet is known for its green color, which is due to the presence of diatomic carbon (C2) gas in its coma. Diatomic carbon emits a greenish-yellow light when it is excited by sunlight or other radiation. The green color of the comet is therefore a result of this emission process.Comet C/2022 E3 (ZTF) made its closest approach to the sun on March 23, 2022, when it was about 0.9 astronomical units (AU) away from the sun. It was also closest to Earth on March 24, 2022, when it was about 0.55 AU away from our planet.During its close approach to Earth, the comet was visible with binoculars or small telescopes in the northern hemisphere. It appeared as a faint greenish object with a tail pointing away from the sun. After its close approach to the sun and Earth, the comet began to move away from the sun and fade from view.

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.
