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.

In 2017 it was discovered the central source was a long period double degenerate in a 142-day orbit, with masses of 0.555 (Central Star) and 0.70 (White Dwarf Companion) Solar Masses respectively. Although it was suspected to be a binary since 1977, it's true binary nature was only discovered recently.

NGC 1360 was discovered in January 1868 by the German astronomer Friedrich August Theodor Winnecke.^[6]
