Strange and hidden Jupiter-size exoplanet spotted by astronomers and citizen scientists

A group of astronomers and citizen scientists has uncovered a hidden planet the size of Jupiter in a distant solar system, and they should get the chance to see it again soon.

The planet, designated TOI-2180 b, is relatively close to us here on Earth, at only 379 light-years away. But what makes this world special among the sample of known giant exoplanets is that it takes a whopping 261 days to orbit its host star, much longer than most gas giants discovered outside of our solar neighborhood.
