[5] The cluster was independently re-discovered by Guillaume Le Gentil in 1749, then Charles Messier observed it in 1764 and added it to his catalogue.

[9] It has a mass of roughly 746 M☉ and a linear tidal radius of 10.6 ± 1.6 parsecs (34.6 ± 5.2 ly).

The luminosity of the stars that have not yet depleted their lithium implies an age of 22±4 Myr, in good agreement with these older estimates.

[11] A 2020 study of the variable stars in the cluster estimated a new closer distance of 3,800 light years from Earth.

[12] A young stellar object with an outflow, associated with the infrared source IRAS 05327+3404 was discovered in optical observations of M36.
