Rexau

Rexau is a small, dim red dwarf star with 3 planets orbiting it. It is the home star of the njetra.

Properties
Rexau is a particularly small class M6.6V red dwarf star. It is the sole star in the Rexau system. It is roughly 9.3 billion years old, and will last an unreasonably long several trillion of years before fading into a white dwarf. It has a mass of 0.08 solar masses, a radius of 0.133 solar radii, and a luminosity of 0.001 solar luminosities. It has a surface temperature of 2571 degrees Kelvin. Its habitable zone reaches from 0.025 AU to 0.036 AU.

Solar weather
Because Rexau is a red dwarf, it often emits solar winds and flares that wash away the atmospheres of its planets, and endanger spacecraft within a certain radius.

Planets
Rexau is home to 3 total planets.

The first planet is Rimelu, a small Mercury-like planet which has been trying to collect an atmosphere, but solar winds continuously batter its surface to prevent this. It's in an unstable orbit at around 0.008 AU from Rexau.

The next planet is Ku, a vibrant orange super-Jupiter with some thin rings and several moons, one of which is the njetra homeworld Lawa. Its immense magnetosphere shields it and its moons from solar winds. It orbits at around 0.03 AU from Rexau.

The final and most distant planet is a large deep blue ice giant by the name of Merikali, with an intricate moon system. It orbits at around 0.7AU from Rexau.
