"Astronomers Uncover Rare Earth-Like Exoplanet in Major Discovery"
Astronomers have made a rare discovery of a small, cold exoplanet and its massive outer companion, shedding light on the formation of planets like Earth. The planetary system, found around the star HD88986, includes a sub-Neptune planet with a potential orbit of 146 days and an outer companion over 100 times the mass of Jupiter. This discovery is significant in understanding planetary formation and evolution, and the findings pave the way for studying Earth-like planets. The study, led by researchers from various international institutes, utilized high-precision spectrograph data and observations from space telescopes to estimate the mass, radius, and potential transit of the exoplanet.
