Mysteries of one of the most fascinating nearby planetary systems now have been solved. A new study presents the first viable model for the planetary system orbiting one the first stars discovered to have planets – the star named 55 Cancri. Numerous studies since 2002 had failed to determine a plausible model for the masses and orbits of two giant planets located closer to 55 Cancri than Mercury is to our Sun. Astronomers had struggled to understand how these massive planets orbiting so close to their star could avoid a catastrophe such as one planet being flung into the star, or the two planets colliding with each other.
