First 10 minutes: some comments about assignment "Is the controversy about Pluto a scientific controversy?"; science can be affected by culture. Motion of star and planet around the center of mass. Graph of radial velocities interpreted as a system containing 3 planets. Back to "hot jupiters": discovery of 51 Peg b shows the importance of "expecting the unexpected". Alternative explanations of hot jupiters (double star systems, pulsating stars) proved wrong.
