Exploring the TRAPPIST-1 System

The video explores the Trappist 1 star system, a red dwarf located in the constellation Aquarius, which hosts seven Earth-sized exoplanets. These planets, labeled B through H, are in tight orbits around the star. The video details the characteristics of each planet, focusing on their potential habitability, especially Trappist 1D and 1E, which lie within the habitable zone. The challenges of habitability, such as radiation and tidal locking, are discussed. The video concludes with the potential for life in such systems, given the commonality of red dwarf stars.

What is the primary characteristic of the Trappist-1 star compared to our Sun?

• It is much hotter than the Sun.
