110393 Rammstein (provisional designation 2001 TC8) is a background asteroid from the central region of the asteroid belt, approximately 4 kilometers in diameter. It was discovered on 11 October 2001, by French astronomer Jean-Claude Merlin at the Le Creusot Observatory in France. The asteroid was named after the German industrial metal band Rammstein. [2]
Rammstein is a non-family asteroid from the main belt's background population. [3] It orbits the Sun in the central 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 an eccentricity of 0.09 and an inclination of 12° with respect to the ecliptic. [1]
The body's observation arc begins with its first observation made by LONEOS at Lowell 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 is 1⁄48193 of the brightness of the faintest objects that can be seen with the unaided eye. [5]
The asteroid's spectral type is unknown. [1]
Rammstein has not been observed by any of the space-based surveys such as the Infrared Astronomical Satellite IRAS, the Japanese Akari satellite or the NEOWISE mission of NASA's Wide-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 an absolute magnitude of 15.0 and a geometric albedo of 0.20 and 0.06, which roughly correspond to a body of carbonaceous and stony composition, respectively (both types are common in the central asteroid belt). [2] [4] The Minor Planet Center (MPC) similarly estimates the object's mean diameter to be between 3 and 6 kilometers. [5]
As of 2018, no rotational lightcurve of Rammstein has been obtained from photometric observations. The body's rotation period, shape and poles remain unknown. [1] [6]
This minor planet was named after the German NDH-Metal band Rammstein, which in turn took its name from the city of Ramstein after the tragic 1988 air show disaster at Ramstein Air Base. [2] The official naming citation was published by the MPC on 19 February 2006 ( M.P.C. 55989). [7]
