Sedna (prototype of objects of orbital class Sednoids)

Sedna is a dwarf planet or large planetoid in the outer reaches of the Solar System
For nearly all of its orbit, Sedna is even farther from the Sun than at present: its orbit is one of the largest in the Solar System other than those of long-period comets, with its aphelion estimated at 937 AU
937 AU is 31 times Neptune's distance, 1.5% of a light-year (or 5.5 light-days) and well beyond the closest portion of the heliopause, which defines the boundary of interstellar space.
Sedna has an exceptionally elongated orbit, and takes approximately 11,400 years to return to its closest approach to the Sun at a distant 76 AU. The Minor Planet Center currently categorized Sedna as part of the scattered disc, a group of objects sent into highly elongated orbits by the gravitational influence of Neptune. This classification has been contested because its perihelion is too large for it to have been scattered by any of the known planets, leading some astronomers to informally refer to it as the first known member of the inner Oort cloud. It is also the prototype of a new orbital class of objects, the sednoids.
(From Wikipedia)

Asteroid (180689) 2004 HU10 is a common main belt asteroid, nothing special.
I picked it to show the difference in movement,
between 1.5 arcsecs/hour (Sedna) and 29.9 arcsecs/hour (2004 Hu10).

Sky quality mediocre, both the seeing and transparency 2.5/5

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.
