WASP-67 b
WASP-67 b is a hot Jupiter orbiting WASP-67 in the constellation Sagittarius. It lies about 618 light-years from Earth and was discovered in 2012 using the transit method.
How Big Is WASP-67 b?
WASP-67 b has a radius of 12.89 times that of Earth, or 1.15 times the radius of Jupiter. Its mass is 137 times that of Earth.
Is WASP-67 b in the Habitable Zone?
The position of WASP-67 b relative to the habitable zone of WASP-67 cannot be precisely determined from the available orbital data.
Habitable zone of WASP-67: 0.553–1.326 AU (conservative: 0.700–1.257 AU), per Kopparapu et al. (2014). Earth orbits the Sun at 1 AU.

Orbit and Year Length
A year on WASP-67 b — one full orbit around WASP-67 — lasts 4.61 Earth days, shorter than Mercury's 88-day year.
How Was WASP-67 b Discovered?
WASP-67 b was discovered in 2012 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-67 b?
WASP-67 b is 618.0 light-years (189.5 parsecs) from Earth. Light arriving here tonight left the planet around the year 1408. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 10,876,800 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-67 b scores 0.07, ranking #4,794 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.

Frequently Asked Questions About WASP-67 b
Is WASP-67 b habitable?
WASP-67 b is not known to orbit within the habitable zone of WASP-67, and as a hot Jupiter it is an unlikely candidate for life as we know it.
How far away is WASP-67 b?
WASP-67 b is about 618 light-years from Earth in the constellation Sagittarius. A spacecraft traveling as fast as Voyager 1 (about 17 km/s) would need roughly 10,876,800 years to get there.
How big is WASP-67 b compared to Earth?
WASP-67 b has 12.89 times the radius of Earth and about 137 times its mass.
How long is a year on WASP-67 b?
One orbit around WASP-67 takes 4.6 Earth days — short enough that 79 of its years would fit into one Earth year.
