Other Data

Excalibur is resonantly locked with its primary, Artur, orbiting at a distance of 0.30 AU and rotating three times every two orbits. Excalibur has three small moons. While two are typical, the third, Bedwyr, seems to be a captured body, which entered orbit over Excalibur approximately 4,000-5,000 years ago.
