Surprising ‘forbidden planet’ discovered outside our solar system
Astronomers have found an unusually large planet orbiting a small star, located about 280 light-years from Earth.
The unexpected size of the newly discovered world, called TOI 5205b, has led researchers to call it the “forbidden planet.”
The planet-hunting mission, launched in 2018, surveys the light of the nearest and brightest stars to spot dips in starlight, which suggests those stars have planets orbiting them. The TESS mission has found thousands of potential planets.
The exoplanet orbits a red dwarf star called TOI-5205, which is about 40% the size and mass of our sun, and about 5,660 degrees Fahrenheit (3,127 degrees Celsius) in temperature compared with the sun’s blazing average of 9,980 F (5,527 C).
