-== Physical Characteristics in Orbiter ==
-In [[Orbiter]] Castalia appears to be a contact binary, has a mean diameter of about 1800 meters and a mass of 5×10<sup>11</sup> kg. Surface Gravity is about 0.00001 m/s<sup>2</sup>, and escape velocity is about 0.2 m/s. Landing on Castalia near the waist the spacecraft will land on the radius above the texture surface, but, near the ends, it will land below the texture surface.
-== Orbital characteristics in Orbiter ==
-The orbit of Castalia varies from inside the orbit of [[Venus]] to just outside that of [[Mars]], Semimajor axis is about 159 million Km at an eccentricity 0.483, inclination is  of  Orbital period is about 400 days.
