HD 20,794D, a planet six times the mass of Earth, orbits a Sun-like star just 20 light-years away. Its presence was confirmed after years of meticulous analysis, overcoming the limits of detection technology.
Although it lies in the habitable zone, its elliptical orbit presents challenges in determining its true potential for life. Future telescopes may soon provide deeper insights into its atmosphere, making this one of the most exciting exoplanet.
An exoplanet (or extrasolar planet) is a planet that is located outside our Solar System, orbiting around a star other than the Sun. The first suspected scientific detection of an exoplanet occurred in 1988, with the first confirmation of detection coming in 1992.
