Meet TRAPPIST-1 b, one of the fascinating worlds orbiting the ultra-cool dwarf star TRAPPIST-1, discovered in 2016 right from the ground using the charmingly named TRAPPISTCAM at La Silla Observatory. This sizzling little planet is the closest of its stellar siblings to the star, making it a toasty place by alien standards. Although it’s a rocky world, it's definitely not the cozy type — more like a cosmic lava lamp constantly heated by its star. TRAPPIST-1 and its planetary system, about 40 light-years away, have become a celestial celebrity, offering astronomers a tantalizing glimpse of diverse worlds beyond our solar system. TRAPPIST-1 b might be too hot for a vacation, but it’s a superstar in the exoplanet lineup!
