Nept\u00fcn, g\u00fcne\u015f sistemimizdeki dokuz gezegenden bir\u00a0tanesidir. Her ne kadar b\u00fcy\u00fck bir gezegen olsa da Nept\u00fcn, D\u00fcnyam\u0131zdan \u00e7ok uzakta oldu\u011fu i\u00e7in \u00e7\u0131plak g\u00f6zle g\u00f6r\u00fclemez. Gece bulutsuz, a\u00e7\u0131k g\u00f6ky\u00fcz\u00fcnde ve tam karanl\u0131kta Mars ve Ven\u00fcs gibi baz\u0131 gezegenler parlak y\u0131ld\u0131zlar gibi g\u00f6r\u00fclebilirler.

Gezegenlerin y\u0131ld\u0131zlar gibi kendi \u0131\u015f\u0131klar\u0131 yoktur. Sadece G\u00fcne\u015ften ald\u0131klar\u0131 \u0131\u015f\u0131\u011f\u0131 yans\u0131t\u0131rlar. Bu nedenle en parlak g\u00f6r\u00fcnen gezegenler G\u00fcne\u015fe en yak\u0131n olanlard\u0131r. Nept\u00fcn G\u00fcne\u015ften \u00e7ok uzak oldu\u011fu i\u00e7in G\u00fcne\u015f \u0131\u015f\u0131nlar\u0131n\u0131n olduk\u00e7a az bir b\u00f6l\u00fcm\u00fcn\u00fc yans\u0131tabilir.

Nept\u00fcn\u2019\u00fcn bulunu\u015f \u015fekli de ilgi \u00e7ekicidir.

Gezegenler G\u00fcne\u015fin \u00e7evresinde belli bir y\u00f6r\u00fcnge izlerler.
