Messier 93 Observation data (J2000.0 epoch) Right ascension 07h 44.6m Declination −23° 52′ Distance 3.6 kly (1.1 kpc) Apparent magnitude (V) 6.0 Apparent dimensions (V) 22.0′ Physical characteristics Radius 10 Estimated age 100 million years[citation needed] Other designations NGC 2447 See also: Open cluster, List of open clusters Messier 93 (also known as M 93 or NGC 2447) is an open cluster in the constellation Puppis. It was discovered by Charles Messier in 1781.
M93 is at a distance of about 3,600 light years from Earth and has a spatial radius of some 10 to 12 light years. Its age is estimated at some 100 million years.
Walter Scott Houston described its appearance as follows:[1]
Some observers mention the cluster as having the shape of a starfish. With a fair-sized telescope, this is its appearance on a dull night, but [a four-inch refractor] shows it as a typical star-studded galactic cluster.
