naked eye object physical object a physical object visible to the unnaided human eye

open cluster disk star cluster open cluster catalog A comparatively loose grouping (mass range 10²-10³ M)_sun of Population I stars, strongly concentrated in the spiral arms or the disk of the Galaxy (in fact, open clusters give a good indication of where the spiral arms are). Unlike associations, open clusters are dynamically stable. Depending on their age, stars in open clusters "peel off" from the main sequence at different points (the higher the turnoff point, the younger the cluster). (Sometimes called Galactic cluster; NGC 188 is the oldest known open cluster.) varies widely

Hyades + 36 km s^-1 Aldebaran is a foreground star in that region of the sky, it is not a member of the Hyades. disk open cluster catalog 200 naked eye object 40 pc 5 × 10⁸ yr spectral types A1-K
