'''4769 Castalia''' is a near-Earth object of the Apollo group of asteroids. It was discovered by [[w:Eleanor Helin|Eleanor Helin]] at [[w:Palomar Observatory|Palomar Observatory]] on 9 August 1969, and on 28 August 1989, Castalia was observed by radar at [[w:Arecibo Observatory|Arecibo Observatory]], the first asteroid modeled by radar. Castalia was made available in Orbiter by Nighthawke's AsteroidPack v1.00 zip file.

== 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.
