So last night I was about to sleep with the window in front of me. there was a 3 inch gap between the curtains that let me see a small portion of the sky. I could see something magnificently bright in the sky that couldn't be anything but Venus. So while I was looking at it for about 1-2 minutes it gradually moved out of my sight. That seemed pretty fast. I mean I kinda estimated that with such a speed it could move from east to west in less than 2 hours. So is that normal?
The Earth rotates on its axis once every 24 hours. (Well, actually a little less, by about 17 minutes, but close enough.) That's $360^\circ$ in 24 hours, or about $15^\circ$ per hour. $15^\circ$ is 30 times the width of the Sun or Moon. The Sun moves exactly that fast (on average), the stars a smidgen faster, and the Moon a tad slower. (The Moon lags behind the stars by approximately its own width every hour.)
Since Venus is never more than about $45^\circ$ from the Sun, it always sets at most 3 hours after the Sun does, and rises at most 3 hours before.
This was likely the international space station. It can take up to 5 minutes for the ISS to pass from horizon to horizon. However, later in the night, that time gets shorter as the suns relative angle to the ISS and you changes. It will be quickly back into the shadow of the earth and lower on the horizon, staying low throughout. It can reach up to -8 magnitude on occasion. This is very easy to see, however near midnight it would likely be closer to 0 or 1.
