Measurements and positionShow

Position: Right ascension 20h 06m 04.8s Declination −21° 55′ 20″J2000; Where the object sits on the sky, in the coordinate system astronomers use. Right ascension is the east–west figure and declination the north–south one; J2000 names the reference date they are measured against.
Brightness: 8.26; Apparent magnitude. The scale runs backwards — a smaller number is brighter, and around 6 is roughly the faintest the unaided eye can see from a dark site.
Apparent size: 3.6 arcminutes; How large the object looks from here, not how large it is. The full Moon is about 30 arcminutes across, which is a useful thing to compare against.
