TL;DR I saw a star-like point of light moving unpredictably changing directions, mostly smooth motion with occasional jerks, no sound, stable brightness.

Around 4-5 years ago, I was camping near the sea on a rocky coastal area in Crimea, Ukraine. It was nighttime, visibility was pretty good and I could clearly see the surrounding rocks and stars. While lying on a small overhang, I noticed a small point of light in the sky that looked exactly like a star, but unlike the other stars, it was moving. Its motion was mostly smooth but occasionally made sudden directional changes or jerks. The object never stopped, didn’t follow a straight line, and didn’t behave like a satellite or aircraft. There was no sound. I could look away and then notice the object again, still moving randomly. Its brightness remained fairly stable, and eventually, it flew out of sight as I left the area. I’m not claiming anything extraordinary, I’m just genuinely interested in whether this could have been a rare atmospheric or plasma phenomenon, some unusual aircraft, or something else entirely. Has anyone here observed something similar or can suggest plausible explanations?
