  • HD 75289 System - A nearby yellow dwarf star (94.4 ly) with a Red Dwarf about 620 AU. 0.4 Jupiter massed planet Ab was predicted to be a Cloudy Hot Jupiter by Extrasolar Visions website, which have bright silicate clouds above its dark sodium haze. However, by studying its star's light, it has been concluded that the planet must have a very low albedo for a Hot Jupiter, otherwise the planet's reflected light would have been detected. Star B would only appear as bright as Saturn does from the planet.
