Grigg-Skjellerup em 3D: posição e órbita ao vivo

Um cometa com cerca de 2,6 quilômetros. A sonda Giotto da ESA passou por ele a cerca de 200 quilômetros em julho de 1992, depois do seu encontro com o Halley.Grigg-Skjellerup é mostrado na sua posição real, calculada a partir das efemérides NASA/JPL. A vista se abre sobre Grigg-Skjellerup; você pode viajar no tempo, alternar entre a visão geral educativa e a viagem em escala real, e compará-lo com todos os outros corpos do Sistema Solar.
