Hartley 2 em 3D: posição e órbita ao vivo

Um pequeno cometa com cerca de 1,6 quilômetro, visitado pela EPOXI, a missão estendida da sonda Deep Impact da NASA.Hartley 2 é mostrado na sua posição real, calculada a partir das efemérides NASA/JPL. A vista se abre sobre Hartley 2; 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.
