GJ 3323 and Its Two Known Planets

GJ 3323 is a nearby star just 17.5 light-years away. Its spectral type of M4 makes it a small, cool red dwarf. The star has a mass of 0.164 solar masses and a radius of 0.119 solar radii, both smaller than the Sun's, and its temperature of 3160 K is cooler than the Sun's. Two planets are known to orbit this host.

Both planets were discovered in 2017 using the radial velocity method. GJ 3323 b has a minimum mass of 2.02 Earth masses and an orbital period of 5.36 days, the shortest year among the listed planets. GJ 3323 c has a minimum mass of 2.31 Earth masses and an orbital period of 40.5 days, the longest year among the listed planets. Each minimum mass is a lower bound on the planet's true mass, and both are larger than Earth's.
