- This article discusses the discovery of a new type of planetary system, known as a "super-Earth," orbiting the nearby star Proxima Centauri.
- The super-Earth, named Proxima d, is about 1.5 times the mass of Earth and orbits Proxima Centauri, the closest star to our solar system, every 5.2 days.
- The discovery of Proxima d adds to the growing number of exoplanets found around nearby stars and provides insights into the diversity of planetary systems in our galaxy.
