May (minor planet designation: 348 May) is a large Main belt asteroid.[1] It was discovered by Auguste Charlois on 28 November 1892 in Nice, and was named for the German author Karl May.[3] This asteroid is orbiting the Sun at a distance of 2.97 AU with a period of 5.12 years and an eccentricity (ovalness) of 0.067. The orbital plane is inclined at an angle of 9.7° to the plane of the ecliptic.[1] During its orbit, this asteroid has made close approaches to the dwarf planet Ceres. For example, in September 1984 the two were separated by 6.3 Gm (0.042 AU).[4]

Analysis of the asteroid light curve generated from photometric data collected during 2007 provided a rotation period of 7.385±0.004 h with a brightness variation of 0.16±0.03 in magnitude. This is consistent with an estimate from a 2006 study.[5] It is classified as a G-type asteroid[4] and spans a diameter of approximately 83 km.[1]
