Sobre esta observación
Neptuno aparece aquí como un pequeño punto luminoso, algo lógico para el planeta más lejano del Sistema Solar. Es un gigante helado situado a unos 4.500 millones de kilómetros del Sol, unas 30 veces la distancia entre la Tierra y nuestra estrella.
Aunque su diámetro es casi cuatro veces el terrestre, está tan lejos que incluso con telescopio suele verse diminuto. Su atmósfera alberga algunos de los vientos más rápidos conocidos entre los planetas.
Curiosidad: Neptuno fue descubierto en 1846 después de que su posición se predijera mediante cálculos matemáticos a partir de pequeñas anomalías en la órbita de Urano.
