Gray & Garrison (1987) spectrally classified the star as A0IVnn, with the "nn" implying very fast projected rotational velocity. With a projected rotational velocity (vsini) of 340 kilometers per second, van Belle (2008) predicted the star to be extremely oblate, with its rapid rotation resulting in an equatorial radius being 31% larger than its polar radius.

	Representing a real mountain of Arcadia in the central Peloponnese, Mons Maenalus was a subdivision of Boötes introduced by Johannes Hevelius in his ''Firmamentum Sobiescianum'' star atlas published in 1690, where it was depicted with Boötes standing on its slopes. However, in his accompanying catalogue Hevelius listed its stars under Boötes, not as a separate constellation. The mountain appeared on many later maps made by other astronomers including Bode, below, but always as part of Boötes, and it never had an independent existence.</blockquote>		Representing a real mountain of Arcadia in the central Peloponnese, Mons Maenalus was a subdivision of Boötes introduced by Johannes Hevelius in his ''Firmamentum Sobiescianum'' star atlas published in 1690, where it was depicted with Boötes standing on its slopes.
