Asteroid (2)Pallas and (9916)Kibirev

Here we have two asteroids. (2)Pallas is a really large one with a mean diameter of 513 km.
(9916)Kibirev is a small one with a diameter of only about 6 km.

Asteroid (2)Pallas is the second asteroid discovered, after Ceres.
Discovered on 28.03.1802 by Heinrich Wilhelm Olbers
Pallas is the second or third-largest asteroid (uncertain)

(9916) Kibirev was discovered on 03.10.1978, by astronomer Nikolai Chernykh

My main object was Pallas, actually I wanted to capture the movement, and eventually do photometry of it. Later as I checked the images I found the smaller asteroid and I could identify it as (9916)Kibirev.
The photometry of Pallas wasn't successful because of the extreme brightnes of it(burned out). But the photometry of Kibirev succeded, and produced a nice light-curve for the 2.5h session (brightnes fall about 0.2 Mag).
The rotation period of Kibirev is about 15 hours.

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.
