What is the names of the planets on Jupiter?
Jupiter has no planets but it has a lot of moons. The big ones, discovered by Galileo are Io, Europa, Ganymede and Callisto. Galileo wanted the credit for the discovery but did not want to reveal the discovery, so he announced it with a Latin anagram, so that when someone else made the discovery he could say, 'aha! I knew that first!'. That's the way they used to behave in those days (Galileo anyway).

Why was it difficult for ancient astronomers to explain about the apparent retrograde motion?
If, as ancient astronomers thought, that our Earth was the center point of rotation for other planets, then it is difficult to explain why those planets would move in a direction opposite to their rotation. Ptolemy came up with a solution that worked, but it was a cumbersome one. Nicolae Copernicus was able to show that this retrograde motion could be explained easily if it were assumed that our Sun was the actual center of rotation of the planets.
