Giacobini-Zinner en 3D: posición y órbita en directo

Un pequeño cometa de unos 2 kilómetros, origen de los meteoros Dracónidas. El 11 de septiembre de 1985, el International Cometary Explorer pasó junto a él: la primera sonda en sobrevolar un cometa.Giacobini-Zinner se muestra en su posición real, calculada a partir de las efemérides NASA/JPL. La vista se abre sobre Giacobini-Zinner; 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.
