Nicknamed the Spare Tyre Nebula,[3] IC 5148 is a planetary nebula located around 1 degree west of Lambda Gruis in the constellation of Grus (The Crane).[4] It was discovered by Australian amateur astronomer Walter Gale in 1894. Around 3000 light-years distant, it is expanding at a rate of 50 kilometres a second, one of the fastest of all planetary nebulae.[3]

The central star of the planetary nebula has a spectral type of hgO(H).[5]
