One was a UFO and four were theoretical. There are retrograde orbit satellites but I suspect that there aren't many deleberately set up that way. There is no problem in having them orbit east to west instead of west to east (except if you wanted a geosychronuos orbit that would be impossible of course) the point is there are drawbacks to that approach. The biggest is that you would have to use more fuel to compensate for the motion the rocket had on the launch pad as a result of the earths rotation. Fuel costs money and you would have to have a particular need for the satellite to travel east to west to waste that money on extra fuel if it wasn't necessary. You mentioned India as a possible country that has sent up retrograde satellites and I have read that somewhere myself. Another is Israel who sent its first satellite retrograde as it did not want to send it up over neighbouring countries (politics you know). Instead it was launched over the Mederteranean and that requires of course an east west launch. There is a whole slew of satellites and other objects that have orbited or are orbiting in a retrograde orbit. I suggest you do do a Google search on satellite situation report. The second listing in that search should be a catalogs and data link. There are zip files on that site you can download that gives the orbital elements of the various objects we humans have sent up. It lists the type country involved etc and also shows the orbital inclination. Anything with an inclination of greater than 90 degrees is in a retrograde orbit. You will see that there are quite a few. > That seemed strange. So I ask, lets consider the east west launcher.

We would see it circling the earth twice. No the Sun does not come into it. If you wished to send up a satellite in the east west direction and to orbit at the same height as the usual east west geosynchronous satellite the same parameters are needed. The satellite will be obiting at the height of approximately 37000 km and a speed of around 7000 mph. The only difference involves the expenditure of more feul as the rocket has to overcome the speed of rotation at the launch site that is imparted by the rotating earth. As you say it will be orbiting the earth twice every 24 hours. > As I said before.
