Comets, even when not visible, are fascinating objects. Perhaps because finding them, catching the best moment to photograph them, and processing their images are not always obvious.This is 103P/Hartley, a peanut-shaped periodic comet with a 6.48-year orbital period. It is located in Gemini, at 0.39 AU from Earth and 1.06 AU from the Sun. Its apparent magnitude is 9.2, requiring a binocular or a small telescope to observe it. It was discovered in 1986 by Malcolm Hartley and visited by the Deep Impact spacecraft in 2010 as part of the EPOXI mission. It has a thin and elongated tail, inclined by 45° with respect to the Earth’s line of sight, but barely visible due to its low brightness and the sky glow.

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.
