The tenth edition of the Catalogue of Cometary Orbits was issued in 1995. It contained orbits for 1472 comets observed from -239 to the end of 1994, as well as numerous statistical tables. This was the first edition that utilized the current comet designation system. A limited quantity of the original printing of this catalogue have become available. Complete your astronomical library! The condition is generally excellent: some copies have minor cover fading and/or slight blemishes, but nothing that diminishes the information contained within.
