Rimelu

Rimelu is a small hot terrestrial planet in low orbit of Rexau.

Properties
Rimelu is a Mercury-like, metal rich planet in orbit of Rexau. It has a mass of 0.07 M🜨, a radius of 0.402🜨, and an average density of 1.08 D🜨. It has a high core mass fraction. Its surface gravity is 0.434g. It is tidally locked to Rexau. It has no moons, magnetosphere, atmosphere, or liquid. On the day side, the planet is around the temperature 531K (258C), but on the night side, the temperatures are relatively near to absolute zero.

Orbit
Rimelu has an unstable orbit at around 0.008 AU from Rexau. The gravitational influence of nearby Ku keeps its orbit chaotic. It orbits about once every day🜨. Its orbit is currently inclined 12 degrees, and has an eccentricity of 0.102.

Significance
As the only planet in the Rexau system apart from Ku, it has some significance to the njetra residing in the system. There are currently a few njetra scientific and resource extraction bases on Rimelu, mostly on the night side to protect from heat and solar weather.

Dyson swarm project
Its proximity to the parent star and richness in resources makes it a perfect candidate to begin a Dyson swarm or Dyson sphere from. On the night side of Rimelu, protected from the solar weather, is a factory forging solar panel satellites for a Dyson swarm around Rexau. It is expected to finish in 2,240 years, and begun roughly 120 years ago. Even this small amount of completion has given a new era of productivity to the njetra.
