What Wikipedia says

J1407b is an astronomical object proposed to explain a series of eclipse-like dimming events observed in the star V1400 Centauri during 2007. These dimming events were recorded by automated telescopes that year but were not identified until 2010, when Mark Pecaut and Eric Mamajek analyzed the data.
