An Amber ball, quite small in diameter

I just glanced out of the window randomly and i spotted an amber/orange circle, not large, travelled steadily, then dissapear, heading from the South towards the North. I didnt think much of it at first but then noticed that it had no flashing lights/beacons, like a civilian aircraft would have. Even military aircraft would have a beacon or strobe lights to identify themselves. The strange thing is, i only saw this object for a few seconds, it appeared to fly in a steady altitude, heading North, fairly high, to my guess, 20.000- 40.000 foot MSL. After a few seconds, it dissapeared. It's pretty cloudy over here, but i know for sure that it was no chinese lantern of anything similar as it was moving at a steady but quick speed. Also, i listened but there was no sound at all. I researched a lot into non-man made possibilities, and i am a huge enthusiast of military and commercial aircraft, and i can honestly say, what i have observed, i believe was not man-made.

I just honestly believe I have witnessed something out of the ordinary.
