Datos

WASP-47 c tiene una temperatura de equilibrio de entre −50 y +50 °C.

Cómo se descubrió

Primer planeta descubierto en 2012, por tránsito y velocidad radial (NASA Exoplanet Archive).

Sus planetas

WASP-47 b — 13 times Earth's width, a giant, Jupiter-sized or more; its year lasts 4 days; about 1,000 °C, hot enough to melt rock; found in 2012 by transit.
WASP-47 c — about 450 times Earth's mass; its year lasts 590 days; about −26 °C, below freezing; found in 2015 by radial velocity.
WASP-47 d — 3.7 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 9 days; about 610 °C, hotter than boiling water; found in 2015 by transit.
WASP-47 e — 1.8 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 19 hours; about 1,700 °C, hot enough to melt rock; found in 2015 by transit.

De dónde proceden estos datos

NASA Exoplanet Archive, Planetary Systems Composite Parameters (fetched 2026-11-02). Composite values: where a planet's size or mass was not measured, the archive estimates it from the other.
This research has made use of the NASA Exoplanet Archive, which is operated by the California Institute of Technology, under contract with NASA under the Exoplanet Exploration Program.
