HIP 67537 b
HIP 67537 b is a exoplanet orbiting HIP 67537 in the constellation Centaurus. It lies about 379 light-years from Earth and was discovered in 2017 using the radial velocity method.
Is HIP 67537 b in the Habitable Zone?
The position of HIP 67537 b relative to the habitable zone of HIP 67537 cannot be precisely determined from the available orbital data.
Orbit and Year Length
A year on HIP 67537 b — one full orbit around HIP 67537 — lasts 2,523.6 Earth days, longer than an Earth year. It orbits at an average distance of 4.807 AU. Its orbit is highly elliptical (eccentricity 0.59), swinging dramatically closer to and farther from its star.
How Was HIP 67537 b Discovered?
HIP 67537 b was discovered in 2017 using the radial velocity method, with observations from Multiple Observatories.
The radial velocity method measures the subtle wobble of a star caused by the gravitational pull of an orbiting planet, visible as periodic shifts in the star's light spectrum. The size of the wobble reveals the planet's minimum mass.
How Far Away Is HIP 67537 b?
HIP 67537 b is 378.5 light-years (116.0 parsecs) from Earth. Light arriving here tonight left the planet around the year 1648. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 6,661,600 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. HIP 67537 b scores 0.34, ranking #829 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.
