TRAPPIST-1e is one of the seven exoplanets orbiting the ultra-cool dwarf star TRAPPIST-1, located approximately 39 light-years away in the constellation Aquarius. TRAPPIST-1e is similar in size to Earth and receives a similar amount of energy from its star, making it a potentially habitable planet. It orbits within the habitable zone of TRAPPIST-1, where liquid water could exist on its surface. The planet's composition and atmosphere are still under investigation, but scientists believe it may have a rocky surface and the potential for a stable climate. TRAPPIST-1e has attracted significant attention in the search for extraterrestrial life, and future studies will provide more insights into its potential habitability.
