NASA scientists have announced the discovery of an Earth-sized planet with an icy surface in a distant solar system. The planet, named TOI-561b, is located around 260 light-years away and orbits a star that is significantly older than our sun. TOI-561b is one of the oldest known rocky exoplanets, estimated to be around 10 billion years old. Its surface temperature is around minus 350 degrees Fahrenheit, making it too cold to support life as we know it.
The discovery of TOI-561b provides valuable insights into the formation and evolution of rocky planets in our galaxy. Studying planets like TOI-561b helps scientists better understand the diversity of exoplanets and the factors that influence their characteristics. This discovery underscores the importance of continued exploration and research efforts in the field of exoplanet studies.
