Скачать или смотреть HD 137010 b Frozen Twin

HD 137010 b has been referred to in the media as an "Earth's cold twin," or "Frozen Twin", due to its Earth-like size and orbital period, despite having a potentially frigid surface temperature.
Key Characteristics
Size and Orbit: The exoplanet is only slightly larger than Earth (about 6%) and orbits its star, a K-dwarf located 146 light-years away, every 355 days, similar to Earth's year.
Temperature: Although it is located within its star's habitable zone (the region where liquid water could exist), its host star is cooler and dimmer than the Sun. The planet receives less stellar energy than Earth, and without a thick, heat-trapping atmosphere, its average surface temperature is estimated to be around -68°C (-90°F), colder than Mars' average temperature.
Habitability Potential: The "Frozen Twin" nickname is used because the planet is likely ice-covered under current models. However, scientists suggest that if it possesses a thick, carbon dioxide-rich atmosphere capable of creating a strong greenhouse effect, it could still potentially harbor liquid water beneath a surface layer of ice.
Detection: The planet was discovered in 2026 by NASA scientists analyzing archival data from the retired Kepler space telescope's K2 mission and confirmed with high-precision checks from other observatories. The discovery is significant because it is one of the nearest Earth-sized planets found in a long orbit around a sun-like star, making it a good candidate for future detailed atmospheric analysis with advanced telescopes.
