Tetis en 3D: posición y órbita en directo

Una luna helada casi tan brillante como la nieve fresca, marcada por el vasto cañón Ithaca Chasma y la cuenca de impacto Odysseus.Tetis se muestra en su posición real, calculada a partir de las efemérides NASA/JPL. La vista se abre sobre Tetis; puede viajar en el tiempo, alternar entre la vista general educativa y el viaje a escala real, y compararlo con todos los demás cuerpos del sistema solar.
