The planets closely orbit Barnard’s Star, zipping around their stellar host in a matter of days, compared with the year it takes Earth to complete one orbit around the sun. The outermost planet takes less than seven days to complete one orbit, while the innermost planet has an orbital peri...
"With the current dataset, we can confidently rule out any planets more massive than 40 to 60% of Earth's mass near the inner and outer edges of the habitable zone," sBasant said.. "Additionally, we can exclude the presence of Earth-mass planets with orbital periods ...
No planets have been confirmed orbiting The Stars Formerly Known As Alpha Centauri, but in March 2022 astronomers published a model of what an Earth-sized planet might look like in the system’s habitable zone. Their calculations yielded a world similar to Earth in water content but richer in...
From the star’s wobbles, the team deduced the highly likely presence of a third planet in the system. Orbiting its host star at 0.029 times the distance between Earth and the sun, Proxima d sits within Proxima Centauri’s habitable zone, the region around the star in which ...
Earth may have a twin orbiting one of our nearest stellar neighbors, a new study suggests. University of California, Santa Cruz graduate student Javiera Guedes used computer simulations of planet formation to show that terrestrial planets are likely to have formed around one of the stars in the ...
This planet is about 1.3 times that of the Earth and has a temperature suitable for liquid water to exist on its surface , according to the study .
Here we propose that two modulation periods whose ratio of large-to-small values is not an integer number imply the existence of an atmosphere if detected at an exoplanet, but it remains ambiguous whether the atmosphere is optically thin or thick, as for Earth or Venus respectively. Multi-...
Planets in the habitable zone around Proxima receive an average dose of X-rays about 500 times larger than the Earth, and 50,000 times larger during a big flare, according to NASA.
