HD 97048 b
HD 97048 b is a cold gas giant orbiting the Be9.5/AO star HD 97048 in the constellation Chamaeleon. It lies about 600 light-years from Earth and was discovered in 2019 using the disk kinematics method.
Is HD 97048 b in the Habitable Zone?
The position of HD 97048 b relative to the habitable zone of HD 97048 cannot be precisely determined from the available orbital data.
Orbit and Year Length
HD 97048 b orbits at an average distance of 130.000 AU.
How Was HD 97048 b Discovered?
HD 97048 b was discovered in 2019 using the disk kinematics method, with observations from Atacama Large Millimeter Array (ALMA).
Disk kinematics infers a still-forming planet from disturbances it carves into the rotating disk of gas and dust around a young star.
How Far Away Is HD 97048 b?
HD 97048 b is 599.7 light-years (183.9 parsecs) from Earth. Light arriving here tonight left the planet around the year 1427. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 10,554,720 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. HD 97048 b scores 0.07, ranking #4,944 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.
