NGC 1360, also known as the Robin's Egg Nebula,[4] is a planetary nebula in the constellation of Fornax. It was identified as a planetary nebula due to its strong radiation in the OIII (oxygen) bands. Reddish matter, believed to have been ejected from the original star before its final collapse, is visible in images.[5] It is slightly fainter than IC 2003.

The central star of the system was suspected to be binary since 1977, but was only confirmed in 2017. The central source consists of a low-mass O-type star and a white dwarf, with masses of 0.555 M☉ and 0.679 M☉ respectively.[6]

NGC 1360 was discovered in January 1868 by the German astronomer Friedrich August Theodor Winnecke.[7]

NGC 1360 ist die Bezeichnung eines planetarischen Nebels im Sternbild Fornax. NGC 1360 hat eine Helligkeit von 9,4 mag und eine Winkelausdehnung von 11,0' × 7,5'. Der planetarische Nebel zählt zu den Objekten mit den meisten unabhängigen Entdeckern[5]: Die Erstbeobachtung gelang Lewis Swift im Jahr 1859. Allerdings veröffentlichte er diese Beobachtung erst 1885, so dass die Astronomen Ernst Wilhelm Leberecht Tempel (1861), Friedrich August Theodor Winnecke (1868) und Eugen Block (1879) das Objekt unabhängig voneinander fanden und beschrieben.[6]
