24260 Kriváň, provisional designation 1999 XW127, is a stony Eunomian asteroid from the middle region of the asteroid belt, approximately 8 kilometers in diameter. It was discovered by Slovak astronomer Peter Kušnirák at the Czech Ondřejov Observatory on 13 December 1999.
The asteroid is a member of the Eunomia family, a large group of stony S-type asteroids and the most prominent family in the intermediate main-belt. It orbits the Sun at a distance of 2.3–2.9 AU once every 4 years and 2 months (1,529 days). Its orbit has an eccentricity of 0.13 and an inclination of 14° with respect to the ecliptic. The first precovery was taken at the Australian Siding Spring Observatory in 1976, extending the asteroid's observation arc by 23 years prior to its discovery.
In December 2011, a rotational light-curve was obtained for this asteroid from photometric observation by U.S. astronomer James W. Brinsfield at the Via Observatory in Thousand Oaks, California. It gave a well-defined rotation period of 3.318±0.001 hours with a brightness variation of 0.42 in magnitude (U=3).
According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, the asteroid measures 8.3 kilometers in diameter and its surface has an albedo of 0.28, while the Collaborative Asteroid Lightcurve Link assumes a standard albedo of 0.21 – derived from 15 Eunomia, the family's largest member and namesake – and calculates a diameter of 8.4 kilometers, based on an absolute magnitude of 12.7.
