'''Kepler 533''' is a star of spectral type K3. It is 994.8 light-years away in the constellation [[Astronomy:Cygnus (constellation)|Cygnus]], and is 0.72 times the radius of the sun and 0.78 times the mass. It has at least [[Astronomy:Kepler-533b|1 exoplanet]], a hot Neptune.<ref>{{Cite web|title=Kepler-533|url=http://www.exoplanetkyoto.org/exohtml/Kepler-533.html|access-date=2020-12-25|website=www.exoplanetkyoto.org}}</ref><ref>{{cite web |last1=Huffman |first1=Darrell |title=Gravity Simulator {{!}} Kepler-533 - System With 1 Exoplanet |url=https://gravitysimulator.org/exoplanets/kepler-533-system-with-1-exoplanet |website=gravitysimulator.org |access-date=15 January 2021 |language=en}}</ref>
