WASP-88 b
WASP-88 b is a hot Jupiter orbiting WASP-88 in the constellation Indus. It lies about 1,708 light-years from Earth and was discovered in 2014 using the transit method.
How Big Is WASP-88 b?
WASP-88 b has a radius of 16.37 times that of Earth, or 1.46 times the radius of Jupiter. Its mass is 133 times that of Earth.
Is WASP-88 b in the Habitable Zone?
The position of WASP-88 b relative to the habitable zone of WASP-88 cannot be precisely determined from the available orbital data.
Habitable zone of WASP-88: 1.608–3.737 AU (conservative: 2.037–3.543 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Orbit and Year Length
A year on WASP-88 b — one full orbit around WASP-88 — lasts 4.95 Earth days, shorter than Mercury's 88-day year.
How Was WASP-88 b Discovered?
WASP-88 b was discovered in 2014 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-88 b?
WASP-88 b is 1,708.3 light-years (523.8 parsecs) from Earth. Light arriving here tonight left the planet about 1,708 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 30,066,080 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-88 b scores 0.06, ranking #5,210 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.

Frequently Asked Questions About WASP-88 b
Is WASP-88 b habitable?
WASP-88 b is not known to orbit within the habitable zone of WASP-88, and as a hot Jupiter it is an unlikely candidate for life as we know it.
How far away is WASP-88 b?
WASP-88 b is about 1,708 light-years from Earth in the constellation Indus. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 30,066,080 years to get there.
How big is WASP-88 b compared to Earth?
WASP-88 b has 16.37 times the radius of Earth and about 133 times its mass.
How long is a year on WASP-88 b?
One orbit around WASP-88 takes 5.0 Earth days — short enough that 74 of its years would fit into one Earth year.
