Measurements and positionShow
Position
Right ascension 06h 45m 59.9s Declination −20° 45′ 15″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
4.50
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
12.0 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.
