The second one is an out of focus blob and the first is a nondescript dot. It'd probably be more interesting to hear what it was doing. Satellites go fairly fast across the sky but they go in straight lines at a constant speed, and they don't stop, reverse or turn.

Second one is not out of focus. its a zoom of the first shot. Did over 100 shots on both iPhone and with DSLR all looked the same.

It just "hanged" there for about 20 minutes and then vanished. Did not move at all, did not change the lighting.

You see that "fuzzy ring surrounding a darker area" look? That is what a point light source looks like when it isn't in focus. In that case, zooming it is just going to give you a bigger blur.
