Notes.Column 1, object name; Cols. 2 and 3, object diameter at apogee and perigee; Cols. 4 and 5, minimum and maximum V-band magnitude for planets and solar system bodies, and total magnitude for the stars; Cols. 6 and 7, minimum and maximum values on rPSF using PSFV,0m for the Sun, the Moon, and the planets, and declination for the stars; and Col. 8, additional comments. Only approximate values on the diameters, magnitudes, and coordinates are presented here (see any book on planetary science).
