Consider two main sequence K-stars. Each star has been measured for a periodic wobble in its velocity curve. Which star has the closest planet (the planet with the smallest orbit)?
A) The planet orbit sizes can't be determined from the information provided.
B) The star with a period of 1 month
C) The star with a period of 2 months

The star with a period of 1 month has a smaller orbit because the shorter the period of a planet's orbit, the closer it is to its star. Therefore, it is likely that this star has the closest planet.
