Measurements and positionShowHide
- Position
- Right ascension 12h 18m 57.5s Declination +47° 18′ 14″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
- 9.29
- 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
- 17.0 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.
