HD 97048 b
- Year
- 956.8 years
- Distance from star
- 130 AU
- Mass
- 2.5 Jupiters
- Size
- 13 × Earth
- Temperature
- ≈ 63 K (-210 °C)
- Found
- 2019, disk kinematics (Atacama Large Millimeter Array (ALMA))
Masses found by the wobble method are minimums, because the orbit's tilt is unknown. Temperatures are equilibrium estimates for a bare planet, before any atmosphere.
