WASP-24 b
WASP-24 b is a hot Jupiter orbiting WASP-24 in the constellation Virgo. It lies about 1,051 light-years from Earth and was discovered in 2010 using the transit method.
How Big Is WASP-24 b?
WASP-24 b has a radius of 15.47 times that of Earth, or 1.38 times the radius of Jupiter. Its mass is 394 times that of Earth.
Is WASP-24 b in the Habitable Zone?
The position of WASP-24 b relative to the habitable zone of WASP-24 cannot be precisely determined from the available orbital data.
Habitable zone of WASP-24: 1.157–2.706 AU (conservative: 1.465–2.566 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Orbit and Year Length
A year on WASP-24 b — one full orbit around WASP-24 — lasts 2.34 Earth days, shorter than Mercury's 88-day year.
How Was WASP-24 b Discovered?
WASP-24 b was discovered in 2010 using the transit method, with observations from SuperWASP.
The transit method watches a star for the tiny, regular dip in brightness that occurs when a planet crosses in front of it. The depth and timing of these dips reveal the planet's size and orbital period.
How Far Away Is WASP-24 b?
WASP-24 b is 1,050.6 light-years (322.1 parsecs) from Earth. Light arriving here tonight left the planet about 1,051 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 18,490,560 years to make the journey.
Earth Similarity Index
The Earth Similarity Index (ESI) scores how physically similar a planet is to Earth, from 0 to 1, based on radius, density, escape velocity and surface temperature. WASP-24 b scores 0.06, ranking #5,156 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.

Frequently Asked Questions About WASP-24 b
Is WASP-24 b habitable?
WASP-24 b is not known to orbit within the habitable zone of WASP-24, and as a hot Jupiter it is an unlikely candidate for life as we know it.
How far away is WASP-24 b?
WASP-24 b is about 1,051 light-years from Earth in the constellation Virgo. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 18,490,560 years to get there.
How big is WASP-24 b compared to Earth?
WASP-24 b has 15.47 times the radius of Earth and about 394 times its mass.
How long is a year on WASP-24 b?
One orbit around WASP-24 takes 2.3 Earth days — short enough that 156 of its years would fit into one Earth year.
