Faint "star" moves across night sky.

I thought it was a faint star just east of the incredibly bright body in the eastern sky. When I noticed it, I thought it moved. I then watched it continue to move using 2 stars as reference points. It continued moving until it passed between the 2 stars and finally left my site. Is it possible what I saw was nasa's unmanned X37 moving in orbit? A satellite wouldn't be visible to the naked eye would it? I've been watching the night sky more this week because of the 2 very bright celestial bodies. I have also witnessed 3 aircraft that I have never seen before, within an hour of each other, headed the same direction. All 3 were flying lower than normal, made less noise than expected, and wingspans didn't seem great enough. I couldn't see any of the body of the aircraft. Each had 3 to 4 rows of white lighted squares on the bottom, under the cockpit, which made it look flat underneath. A single round white light on what should be the wingtips, this is how I gauged wingspan, and 2 rectangular white lights at the center of what should be the tail. Again, I couldn't see the bodies of said aircraft with exception to the lighted squares toward the nose. Any insight into what these sightings are or might be would be very helpful.
