Earth-sized planet in a 355-day orbit emerges as top life-search candidate

Astronomers have identified HD 137010 b, an Earth-sized world orbiting a nearby K-dwarf in about 355 days. Discovered from a single transit and located 146 light-years away, it sits near the star’s habitable zone and offers a prime opportunity for atmospheric follow-up, though confirmation requires another transit or radial-velocity measurements. Its brightness and proximity make it an especially attractive target for future missions like ESA’s PLATO, potentially guiding the search for life beyond Earth.

Nearby Earth-Sized World HD 137010 b Sparks Habitability Debate

Astronomers using Kepler data have identified an Earth-sized exoplanet, HD 137010 b, orbiting a Sun-like–type star about 150 light-years away, with an orbital period of roughly 355 days. The host star is a cooler K-type orange dwarf, meaning the planet may receive less than a third of Earth’s sunlight and could be very cold (below −90°F), though a CO2-rich atmosphere might help trap heat and allow a temperate, potentially watery climate. The candidate was inferred from a single transit in 2017, and follow-up observations (multiple transits) are needed to confirm its habitability and true nature.

Nearby Earth-Sized Exoplanet HD 137010 b Sparks Habitability Debate

Astronomers analyzing Kepler data have identified HD 137010 b, a rocky, Earth-sized exoplanet orbiting a nearby K-type orange-dwarf star about 150 light-years away, with a 355-day year. Its Earth-like size and orbit make it a compelling habitability candidate, potentially aided by a CO2-rich atmosphere, but the planet’s temperature is expected to be very cold and only a single transit was observed. Follow-up observations—ideally three transits—are needed to confirm its existence and assess habitability, especially given potential tidal locking around cooler stars.

Earth-sized Exoplanet Candidate Emerges in a Sun-like Star's Habitable Zone

An international team led by Australian astronomers identified HD 137010 b, about 146 light-years away, as an Earth-sized planet candidate roughly 6% larger than Earth that may lie near its star's habitable zone with a 50% chance of habitability, based on archival NASA Kepler data; confirmation is pending.

Earth-sized exoplanet candidate found near the habitable zone of a sun-like star

An international team led by Australian astronomers identified HD 137010 b, an Earth-sized exoplanet candidate about 146 light-years away that orbits a sun-like star near the outer edge of its habitable zone; the detection came from a single transit in archival Kepler/K2 data and the candidate has an estimated 50% chance of habitability, being roughly 6% larger than Earth.
