Observation data: J2000 epoch | |
Right ascension | 21h 59m 35.2s [2] |
Declination | −39° 23′ 08″ [2] |
Distance | 3000 light years [1] ly |
Apparent magnitude (V) | 16.5 [2] |
Apparent dimensions (V) | 2 ′ x 2 ′ [2] |
Constellation | Grus |
Designations | IC 5150, PK 002-52 1, PSCz P21565-3937, ESO 344-5, IRAS 21565-3937, PN G002.7-52.4 |
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]
