444 Gyptis is a main-belt asteroid that was discovered by J. Coggia on March 31, 1899, in Marseilles.
The spectra of the asteroid displays evidence of aqueous alteration.
[5] In 2004, Kochetova estimated Gyptis to have a mass of 1.25×1019 kg with a high density of 5.53 g/cm3.
[3] The adaptive optics instrument at the W. M. Keck Observatory showed an object with a diameter of 129 km, which is much smaller than the estimate of 160 km from the IRAS observatory measurements, indicating an irregular shape.
[6] Observations of an occultation on October 14, 2007, produced six chords indicating a cross-section ellipsoid of 179×150 km.
