A planet with twice the mass of Jupiter
Scientists have discovered that a dwarf is orbiting a star. The approach of this exoplanet to its host star has turned this planet into a hot Jupiter.
With a radius 1.1 times the radius of Jupiter and a mass 2.3 times the mass of Jupiter, this newly discovered exoplanet, named TOI-4127 b, takes 56.4 days to orbit its host star TOI-4127. This exoplanet is about one-third the distance from the host star to Earth and the Sun, so its surface temperature is 630 degrees Fahrenheit.
TOI-4127 b was discovered by a team of astronomers using NASA's Transiting Exoplanet Survey Satellite, or TESS.
TESS made this observation by observing the tiny changes in light caused by the asteroid's passage, or "transit," in front of its host star.
Since TESS launched in April 2018, this method of finding exoplanets has been very successful, with more than 6,200 exoplanets identified.
Pennsylvania State University researcher Arvind F. This exoplanet TOI-4127 b, discovered by astronomers led by Gupta, orbits a dwarf star located about 1061 light-years away from Earth.
