Exoplanet GJ 3090 b Found Orbiting Star in Retrograde Motion

Astronomers, including students at Queen Mary University of London, have discovered that exoplanet GJ 3090 b orbits its host star in the opposite direction to the star's rotation. This retrograde orbit is unusual and challenges current models of planetary formation and migration. The finding is based on telescope observations, but details on the detection method and system parameters remain limited.
