Encélado em 3D: posição e órbita ao vivo

Uma lua gelada muito brilhante, com uma pluma ativa no polo sul e um oceano subterrâneo.Encélado é mostrado na sua posição real, calculada a partir das efemérides NASA/JPL. A vista se abre sobre Encélado; 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.
