AD Leonis

 

AD Leonis is a young, red dwarf, flare star located only 15.9 light years from Earth.  AD Leonis, like other young stars, is known for violent flares that can sometimes double the star's solar output.

 

Due to its closeness to Earth, the AD Leonis system was one of the first system's explored by humans after the discovery of interstellar travel.  A temporary science base was established orbiting AD Leonis B, with the mission of studying the young system.  Though, no permanent colonies were ever built in the AD Leonis system.

 

Outside of illegal mining operations that occasionally visit the system's outer Kuiper belt, the AD Leonis system is void of human life.
