Por lo general se acepta un di\u00e1metro de 3.7 Km. para la estructura de Steinheim. Pero un an\u00e1lisis gravim\u00e9trico y morfol\u00f3gico, sugieren un tama\u00f1o mucho mayor. Un di\u00e1metro de 6-7 Km. puede ser razonable tal y como propone en un art\u00edculo K. Ernstson\u00a0(1984: A gravity-derived model for the Steinheim impact structure. Int. J. Geosciences, 73\/2, 483-498<\/a>).<\/p>\n

No obstante, incluso en los recientes art\u00edculos sobre modelizaci\u00f3n del proceso de impacto para Steinheim (St\u00f6ffler et al. (2002) :\u00a0http:\/\/www.lpi.usra.edu\/meetings\/lpsc2002\/pdf\/1871.pdf<\/a><\/span>\u00a0, Ivanov and St\u00f6ffler (2005):\u00a0http:\/\/www.lpi.usra.edu\/meetings\/lpsc2005\/pdf\/1443.pdf<\/a><\/span>), un di\u00e1metro peque\u00f1o de 3.8 Km es utilizado para la estructura de Steinheim dando como consecuencia unos resultados bastante dudosos.<\/p>\n
