Kepler-47b
extrasolar planet
Kepler-47b (also known as Kepler-47 (AB) b and by its Kepler Object of Interest designation KOI-3154.01) is an exoplanet orbiting the binary star system Kepler-47, the innermost of three such planets discovered by NASA's Kepler spacecraft. The system, also involving two other exoplanets, is located about 3,400 light-years (1,060 parsecs) away.
Characteristics
Mass, radius and temperature
Kepler-47b is a gas giant, an exoplanet that is near the same mass and radius as the planets Jupiter and Saturn. It has a temperature of 449 K (176 °C; 349 °F). The planet has a radius of 3.03 R🜨, and is thought to have no solid surface. It has a mass of 8.43 M🜨.
Host stars
The planet orbits in a circumbinary orbit around a (G-type) and (M-type) binary star system. The stars orbit each other about every 7.45 days. The stars have masses of 1.04 M☉ and 0.35 M☉ and radii of 0.96 R☉ and 0.35 R☉, respectively. They have temperatures of 5636 K and 3357 K. Based on the stellar characteristics and orbital dynamics, an estimated age of 4–5 billion years for the system is possible.
The public source identifies “Kepler-47b” as extrasolar planet. This brief keeps that definition visible, then builds a research path around Kepler-47b, extrasolar and planet.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Kepler-47b”, the useful work is to connect “extrasolar planet” to the records capable of establishing context and consequence.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 22, 2026. The linked authority identifier is Q9017464. None of the 0 selected statements returned an explicit reference.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
