110393 Rammstein (provisional designation2001 TC8) is a backgroundasteroid from the central region of theasteroid belt, approximately 4 kilometers in diameter. It was discovered on 11 October 2001, by French astronomerJean-Claude Merlin at theLe Creusot Observatory in France. The asteroid was named after the Germanindustrial metal bandRammstein.[2]
Rammstein is a non-family asteroid from the main belt'sbackground population.[3] It orbits the Sun in thecentral asteroid belt at a distance of 2.5–2.9 AU once every 4 years and 6 months (1,630 days;semi-major axis of 2.71 AU). Its orbit has aneccentricity of 0.09 and aninclination of 12° with respect to theecliptic.[1]
The body'sobservation arc begins with its first observation made byLONEOS atLowell Observatory in September 2001, less than a month prior to its official discovery observation at Le Creusot.[2] A telescope is required to see Rammstein, as its maximum brightness is1⁄48193 of the brightness of the faintestobjects that can be seen with the unaided eye.[5]
The asteroid'sspectral type is unknown.[1]
Rammstein has not been observed by any of the space-based surveys such as the Infrared Astronomical SatelliteIRAS, the JapaneseAkari satellite or theNEOWISE mission of NASA'sWide-field Infrared Survey Explorer. Based on a generic magnitude-to-diameter conversion, the asteroid measures 3.0 and 5.5 kilometers in diameter based on anabsolute magnitude of 15.0 and ageometric albedo of 0.20 and 0.06, which roughly correspond to a body ofcarbonaceous andstony composition, respectively (both types are common in the central asteroid belt).[2][4] TheMinor Planet Center (MPC) similarly estimates the object'smean diameter to be between 3 and 6 kilometers.[5]
As of 2018, no rotationallightcurve of Rammstein has been obtained fromphotometric observations. The body'srotation period, shape andpoles remain unknown.[1][6]
Thisminor planet was named after the GermanNDH-Metal bandRammstein, which in turn took its name from the city ofRamstein after the tragic1988 air show disaster atRamstein Air Base.[2] The official naming citation was published by the MPC on 19 February 2006 (M.P.C. 55989).[7]
