Kepler-298d is an exoplanet orbiting Kepler-298, 473.69 parsecs away (1545 light-years). It was discovered in 2014,[2] and orbits its star in the habitable zone. It was thought to be an Earth-like planet,^[ambiguous] but further research places its atmosphere at +2.11 on the HZA scale,^[jargon] meaning it may be an ocean planet with a thick gas atmosphere like a gas dwarf.^[citation needed]
