2500 Alascattalo, provisional designation 1926 GC, is a stony asteroid from the inner regions of the asteroid belt, about 8 kilometers in diameter. It was discovered by German astronomer Karl Reinmuth at the Heidelberg Observatory in southern Germany, on 2 April 1926.[6]
The S-type asteroid is a member of the Flora family, one of the largest groups of stony asteroids in the main-belt. It orbits the Sun at a distance of 2.0–2.5 AU once every 3 years and 4 months (1,225 days). Its orbit shows an eccentricity of 0.10 and is tilted by 7 degrees to the plane of the ecliptic. It has a rotation period of 2.8 hours[5] and an albedo of 0.21, according to observations by the NEOWISE mission of the Wide-field Infrared Survey Explorer.[4]
The minor planet was named for Alaska's mythical beast, supposedly a cross between a moose and a walrus and genetically bred by miners during the Alaska Gold Rush around 1900. The alascattalo is also the epitome of Alaska’s unique sense of humor, "absurding", which is the Alaskan way of dealing with tourists who ask stupid questions. A parade, lasting just four minutes and extending just one block down an alley, is held each year at three minutes past noon on Alascattalo Day, the first Sunday after the third Saturday in November.[2]
