Meet DMPP-1 d, an intriguing world orbiting the star DMPP-1, discovered in 2019 thanks to the keen eyes of the HARPS Spectrograph nestled in Chile’s La Silla Observatory. This planet was uncovered through the clever radial velocity method, which listens to the subtle gravitational tugs a planet exerts on its star—like a stellar dance partner leaving footprints in starlight. While we don’t yet have a flashy nickname or a proper IAU name for DMPP-1 d, this planet adds an exciting chapter to the cosmic story of distant worlds. Although we don’t know its exact distance from Earth, DMPP-1 d reminds us how much there is to explore beyond our solar system, with each discovery sparking curiosity and wonder.
