Title: You observe a star very similar to our own Sun in size and mass. This star moves Post by: killian on Apr 29, 2014 You observe a star very similar to our own Sun in size and mass. This star moves very slightly back and forth in the sky once every 4 months, and you attribute this motion to the effect of an orbiting planet. What can you conclude about the orbiting planet?
A) The planet must be closer to the star than Earth is to the Sun. B) The planet must have a mass about the same as the mass of Jupiter. C) The planet must be farther from the star than Neptune is from the Sun. D) You do not have enough information to say anything at all about the planet.
