Elon Musk Targets Habitable Planet in Close Proximity.

Elon Musk has shown interest in a study detailing the habitability of Proxima Centauri b, an Earth-sized planet located 4.2 light-years away from the Sun and potentially the closest "highly habitable" planet to our Solar System. The planet sits within the "Goldilocks Zone" of the red-dwarf star Proxima Centauri and computer simulations suggest it can sustain liquid water that may harbour living organisms. Despite its relatively close distance, travelling to the planet requires technology that is still in the conceptual stages of development. SpaceX has been developing its reusable Starship rocket with the intention of transporting people and cargo across the solar system.
