NGC4565 and Olympia

Had a couple of clear nights earlier last week and I decided to do some galaxy imaging. One of the targets I chose was NGC4565, an edge on spiral galaxy in the constellation Coma Berenices. I was reviewing some of the raw frames and found a star scooting across the frame. Turns out it’s asteroid Olympia, first discovered 110 years ago. According to Sky Safari, it was shining at magnitude 13.9 and 2.2AU away from Earth. It’s diameter is about 43km. These exposures were around 5 min apiece, showing about 1.5hrs of motion.

It’s pretty cool looking through these frames since there are some plane trails as well. We have four very different scales: the planes (probably ~10km away), asteroid Olympia (+300 million km), the field stars ( < 10000 ly) and NGC4565 (42 million ly).

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.
