Astronomers discover a planet orbiting a faraway star using the
transit method, whereby the periodic dip in the intensity of the received starlight
reveals the orbital period of the planet (the intensity drops when the planet blocks
some of the starlight). By examining other characteristics of the star's light, the
mass of the star is determined to be M = 6.5 × 10³¹ kg.
