Overview
- An international team reports HD 137010 b in The Astrophysical Journal Letters after reanalyzing 2017 data from NASA’s Kepler K2 mission.
- A single shallow transit lasting about 10 hours indicates a radius roughly 6% larger than Earth and an orbital period near 355 days.
- At its estimated distance from the star, the planet receives about 29% of Earth’s sunlight, implying very cold conditions comparable to or below −70°C.
- Climate modeling places the candidate near the outer habitable zone with about a 40% conservative to 51% optimistic chance depending on atmospheric composition.
- The host star’s brightness (about 10th magnitude) and proximity make the system a high-priority target for radial-velocity measurements and future transit searches.
