Kepler-28 is an M-type main-sequence star about away in the northern constellation of Cygnus. With an apparent visual magnitude of 15.036, this star is too faint to be seen with the naked eye. It is orbited by two exoplanets.
==Planetary system== The two transiting planets of Kepler-28 were discovered in 2011 using the Kepler space telescope, and were confirmed in early 2012. They are both warm sub-Neptune gas planets. The planetary parameters were updated in 2023, with lower values for all of mass, radius, and density compared to previous estimates.
