  Over the last few years, several close orbiting ($\sim 0.05$ AU) large mass
planets ($M \sim M_{Jupiter}$) of nearby stars have been discovered. Their
existence has been inferred from tiny doppler shifts in the light from the
star. We suggest that these planets may be made of mirror matter. We also
suggest that some stars such as our sun may have a similar amount of mirror
matter which has escaped detection.
