65 Cybele (sib'-a-lee) is one of the largest asteroids in the main belt. The Cybelian asteroids are named after it. As a C-type asteroid it is dark in color and carbonaceous in composition. In physics, an orbit is the path that an object makes, around another object, whilst under the influence of a source of centripetal force, such as gravity. ...

A year is the time between two recurrences of an event related to the orbit of the Earth around the Sun. ... Inclination is one of the six orbital parameters describing the shape and orientation of a celestial orbit and is the angular distance of the orbital plane from the plane of the reference (usually planets equator or the ecliptic), stated in degrees. ... (This page refers to eccitricity in astrodynamics. ... For the geometric term, see diameter. ... A kilometre (American spelling: kilometer, symbol: km) is a unit of length equal to 1000 metres (from the Greek words khilia = thousand and metro = count/measure). ... In astronomy, a rotation period is the time an astronomical object takes to complete one revolution around its rotation axis. ... The hour was originally defined in Egypt as 1/24 of a day, based on their duo-decimal numbering system (which counted finger joints on each hand). ... An asteroid is a small, solid object in our Solar System, orbiting the Sun. ... C-type asteroids are carbonaceous asteroids. ... In astronomy, absolute magnitude is the apparent magnitude, m, an object would have if it were at a standardized distance away. ... The albedo is a measure of reflectivity of a surface or body. ...

C-type asteroids are carbonaceous asteroids. ... Carbonate is an anion with a charge of -2 and an empirical formula of CO32-. An aqueous solution of carbon dioxide contains a minute amount of H2CO3, called carbonic acid, which dissociates to form hydrogen ions and carbonate ions. ...

First Cybelian stellar occultation was observed on October 17, 1979 in the Soviet Union. A diameter of 230 km was derived, closely matching the diameter of 237 km determined by the IRAS satellite. In this July, 1997 still frame captured from video, the bright star Aldebaran has just reappeared on the dark limb of the waning crescent moon in this predawn occultation. ...
