Researchers have developed the Smaller Than Earth Habitability Model (STEHM) to assess which planets can maintain ...

In a surprising twist to our understanding of exoplanetary systems, astronomers have uncovered three Earth-sized planets orbiting a binary star system known as TOI-2267. This rare configuration, ...

Studying the orbits of thousands of exoplanets shows that large planets tend to have elliptical orbits, while smaller planets tend to have more circular orbits. This split coincides with several other ...

A NASA mission has spotted an Earth-size exoplanet orbiting a small star about 100 light-years away. The planet, named TOI 700 e, is likely rocky and 95% the size of our world. The celestial body is ...

A hot, rocky planet discovered using the Kepler space telescope is the smallest ever found outside our solar system. The new planet, called Kepler-37b, has a radius less than a third the size of Earth ...

A giant planet the size of Saturn orbiting a sun-like star has potentially been identified in our nearest neighbouring stellar system, Alpha Centauri. At just four light years from Earth, Alpha ...
