Set a location and Heavens-Above produces pass predictions for the space station, Starlink trains and thousands of other satellites, each with a chart showing the exact path across your local horizon. Comet and planet ephemerides sit alongside the satellite listings.
The predictions are accurate enough that you can stand outside at the stated minute, look at the stated point on the horizon, and watch it arrive.
