I saw this in the sky and it caught my attention enough to take pictures. This was slow moving bright at first but slowly faded away

This was slow moving slower than an airplane and at first it looked like it had a trail of smoke like an airplane would have but it made no sound. This appeared to be like a orangish light moving slowly across the sky. Because it acted differently I took some pictures and watched it intently. The smoke trail faded away leaving just the light which continued to move very slowly. For approximately 3 minutes I watched it and it slowly faded away until there was nothing. Just yesterday I zoomed in on the images I did with my phone and there is an obvious saucer shape that can be seen. Feel free to contact me if you have any questions.
