- A featured world is a 335 K ice giant orbiting 106.7 AU from a B-type star, with two moons and life on one moon.
Field notes
The featured Vaar system is specified with a 106.7 AU orbit around a B-type star, a temperature of 335 K, and two moons; its description places life on one moon rather than on the planet. The site says its exoplanet collection feeds measured mass, orbit, and star data into the same simulation used for created worlds. Collection totals conflict across the homepage, which cites both 5,579 and 6,347.
