All 5 planets in this system orbit around the primary star.
It has been classed as a hot [[superterran]].
It was discovered by the [[Kepler space telescope]] in 2014 using the [[Methods of detecting exoplanets|transit method]] and was originally classed as a planet candidate, but during a study<ref>{{Cite web|title=Astronomers Catalog Planets That May Be Earthlike|url=https://www.jpl.nasa.gov/news/astronomers-catalog-planets-that-may-be-earthlike|access-date=2021-03-17|website=NASA Jet Propulsion Laboratory (JPL)|language=en}}</ref> by members of the [[Ames Research Center|NASA Ames Research Center]] on two other planets in the Kepler-296 system, [[Kepler-296f]] and [[Kepler-296e]], they were able to confirm that Kepler-296b is an exoplanet with "more than 99% confidence".
