WASP-18 c is the intriguing sibling of the famous hot Jupiter WASP-18 b, orbiting the bright star WASP-18 far out in space. Discovered in 2019 thanks to the clever Transit Timing Variations technique using NASA’s Transiting Exoplanet Survey Satellite (TESS), this planet adds a mysterious twist to the WASP-18 system. Unlike its scorching sibling, WASP-18 c stays more elusive, quietly influencing the timing of its sister’s transits as it orbits their star. While we don’t have a catchy proper name for it yet, WASP-18 c sparks curiosity among exoplanet enthusiasts as a cosmic dance partner in a distant planetary duet. It’s a reminder of how even the tiniest timing shifts from millions of miles away can unveil hidden worlds!
