Characteristics
Kepler-296d has a radius approximately 2.09 times[1] that of Earth and a mass estimated at 5.02[1][4] Earth masses, placing it in the category of Neptune-like exoplanets. The planet orbits its host star every 19.9 days at a distance of approximately 0.118 AU.[1][5] Its orbit has an eccentricity of less than 0.33.[5]
Host Star
The host star, Kepler-296, is an M-type dwarf.[2] These stars are cooler and smaller than the Sun, and often host multiple exoplanets. Kepler-296 is known to host at least five planets.[1][3]
Discovery
Kepler-296d was identified in 2014[1] as part of the data collected by NASA's Kepler space telescope, which monitored the brightness of over 150,000 stars[6] to detect periodic dips in light indicative of planetary transits. The detection of Kepler-296d was achieved through the transit method,[1][5] wherein a planet passes between its host star and the observer, causing a measurable decrease in the star’s apparent brightness.
