The planet was found using data from the NASA Kepler Space Telescope, K2, and the Transiting Exoplanet Survey Satellite.K2-415b was discovered in February 2023. [2]K2-415b is approximately 1.015 times the radius of Earth and is less than 7.5 times the mass of Earth.
The object orbits the Sun but makes slow close approaches to the Earth–Moon system. Between 29 September (19:54 UTC) and 25 November 2024 (16:43 UTC) (a period of 1 month and 27 days) [4] it passed just outside Earth's Hill sphere (roughly 0.01 AU [1.5 million km; 0.93 million mi]) at a low relative velocity (in the range 0.002 km/s (4.5 mph) – 0.439 km/s [980 mph]) and became temporarily ...
Host star is the brightest star with multiple known transiting Earth-size exoplanets. Another transiting planet in the system is suspected. [40] HD 101581 c: 0.0925 6.21 transit 41.7 0.740 ± 0.087 4675 ± 53 Host star is the brightest star with multiple known transiting Earth-size exoplanets. Another transiting planet in the system is ...
The planet is about the size of Venus, so slightly smaller than Earth, and may be temperate enough to support life, the researchers said. Dubbed Gliese 12 b, the planet takes 12.8 days to orbit a ...
Scientists say Speculoos-3 b exoplanet orbits a star that will be one of the last to shine when the universe grows cold and dark
The planet receives about 1.6 times more energy from its star than Earth does from the sun, scientists said. The planet has an average estimated surface temperature only 50°F warmer than Earth’s.
TOI-715 b is a super-Earth exoplanet in the habitable zone of its parent M-type star, TOI-715. [1] [2] [3] The planet is 1.55 times larger than Earth, and is located at 0.083 astronomical units (12,400,000 km) from its star. [4] The planet orbits in the habitable zone of its star and has an equilibrium temperature of 234 K (−39 °C). [4]
The exoplanets were found using a statistical technique called "verification by multiplicity". 95% of the discovered exoplanets were smaller than Neptune and four, including Kepler-296f, were less than 2 1/2 the size of Earth and were in habitable zones where surface temperatures are suitable for liquid water.
