Working on some Star Maps for Dungeon Planet
Proxima Centauri is a red dwarf, a small low-mass star, about 4.25 light-years (1.30 pc) from the Sun in the constellation of Centaurus.
Proxima Centauri's proximity to Earth, its angular diameter can be measured directly. It is about one-seventh the diameter of the Sun.
Proxima Centauri b is a planet orbiting the star at a distance of roughly 0.05 AU (7.5 million km) with an orbital period of approximately 11.2 Earth days.
Its estimated mass is at least 1.3 times that of the Earth.
Moreover, the equilibrium temperature of Proxima b is estimated to be within the range where water could exist as liquid on its surface;
thus, placing it within the habitable zone of Proxima Centauri.
