Nereida, la tercera luna m\u00e1s grande de Neptuno, podr\u00eda ser el \u00fanico sat\u00e9lite intacto que sobrevive del sistema original de este planeta, seg\u00fan sugiere un nuevo an\u00e1lisis de datos del Telescopio Espacial James Webb, un proyecto internacional liderado por la NASA.<\/p>\n

Nereida podr\u00eda ser en realidad un sat\u00e9lite original de Neptuno<\/p>\n

Los hallazgos, publicados en Science Advances, desaf\u00edan una teor\u00eda muy arraigada\u00a0que propone que Nereida, al igual que otras lunas importantes de Neptuno, fue capturada desde fuera de la \u00f3rbita del planeta, en concreto, desde una regi\u00f3n que rodea el sistema solar llamada cintur\u00f3n de Kuiper. Esta hip\u00f3tesis surgi\u00f3, en parte, porque las lunas poseen \u00f3rbitas irregulares y exc\u00e9ntricas, que rara vez ocurren en sistemas de sat\u00e9lites originales a\u00fan intactos.\u00a0<\/p>\n

Ahora, los autores del trabajo liderado por el Instituto Tecnol\u00f3gico de California (EE UU) presentan evidencias que indican que Nereida podr\u00eda ser en realidad un sat\u00e9lite original de Neptuno. Sus an\u00e1lisis de datos espectrosc\u00f3picos de infrarrojo cercano revelaron que la composici\u00f3n de Nereida es diferente a la de otros objetos del cintur\u00f3n de Kuiper.<\/p>\n

<\/a><\/p>\n

Respuesta a la llegada de Trit\u00f3n<\/h2>\n

Se piensa que los objetos helados del cintur\u00f3n de Kuiper son restos de la formaci\u00f3n del sistema solar. De un modo similar a la relaci\u00f3n que existe entre el cintur\u00f3n principal de asteroides y J\u00fapiter, esta es una regi\u00f3n de objetos que podr\u00edan haberse unido para formar un planeta si Neptuno no hubiera estado all\u00ed.<\/p>\n

Las simulaciones indicaron que la \u00f3rbita surgi\u00f3 como respuesta a la llegada de Trit\u00f3n\u00a0cuando fue capturada del cintur\u00f3n de Kuiper<\/p>\n

En cambio, la gravedad de Neptuno agit\u00f3 tanto esta regi\u00f3n del espacio que los peque\u00f1os objetos helados no pudieron unirse y formar un gran planeta.<\/p>\n

El equipo de investigaci\u00f3n explor\u00f3 c\u00f3mo Nereida pudo haber desarrollado su \u00f3rbita altamente exc\u00e9ntrica si no fuera una luna capturada. Las simulaciones indicaron que la \u00f3rbita surgi\u00f3 como respuesta a la llegada de Trit\u00f3n, la luna m\u00e1s grande de Neptuno, cuando fue capturada del cintur\u00f3n de Kuiper.\u00a0Esta es la \u00fanica luna grande del sistema solar que orbita alrededor de su planeta en direcci\u00f3n opuesta a la rotaci\u00f3n del planeta (una \u00f3rbita retr\u00f3grada), lo que confirma que este s\u00ed es un objeto independiente capturado por Neptuno.<\/p>\n

Por eso, se cre\u00eda que los sat\u00e9lites entrantes, como Trit\u00f3n, hab\u00edan aniquilado todos los sat\u00e9lites originales del planeta. El nuevo estudio refuta estas afirmaciones. \u201cNuestra propuesta de g\u00e9nesis de sat\u00e9lites regulares para la luna deja a Nereida como el \u00fanico sat\u00e9lite original intacto de Neptuno\u201d, explican los autores.\u00a0\u201cLas lunas m\u00e1s internas de este planeta, como Proteo, son fragmentos reacumulados de sat\u00e9lites destruidos por la captura de Trit\u00f3n\u201d, a\u00f1aden.<\/p>\n
