It has a mass of 0.6789 solar masses, a radius of 0.7336 solar radii, and a luminosity of 0.2124 solar luminosities. It has a surface temperature of 4578 degrees Kelvin. Its habitable zone reaches from 0.439 AU to 0.633 AU.

Planets
Sykra is home to 4 to 5 planets, depending on how you count them.

First is Therin, a super-earth with an incredibly dense carbon dioxide atmosphere, orbiting at 0.14 AU.

Second is a binary system comprised of Tuvi, a small habitable world home to the Tuvir, and Nykka, a smaller body roughly as large as the Moon. The pair orbits at about 0.471 AU from Sykra.

Third is Mialle, an Earth-size body with a nitrogen atmosphere and frozen lakes of water, orbiting at about 0.802 AU.

Last is Rikasa, a startlingly blue gas giant with an intricate ring and moon system, orbiting at around 1.464 AU. One of its moons, Kema, is home to the Melis.
