Nicknamed the Spare Tyre Nebula,{{cite web|url=http://www.eso.org/public/images/potw1242a/|title=From Cosmic Spare Tyre to Ethereal Blossom|last=ESO|year=2012|work=Picture of the Week|publisher=European Southern Observatory|accessdate=6 February 2014}} IC 5148 is a planetary nebula located around 1 degree west of Lambda Gruis in the constellation of Grus (The Crane).{{cite web | last = Streicher | first = Magda | date = December 2010 | title = Grus—An Elegant Starry Bird | publisher = The Astronomical Society of Southern Africa | work = Deepsky Delights | url =http://www.mnassa.org.za/html/Dec2010/2010MNASSA..69..Dec..229.pdf |pages = 56–59 | accessdate = 7 February 2014}} 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.

The central star of the planetary nebula has a spectral type of hgO(H).{{cite journal|doi=10.1051/0004-6361/202141916|title=Planetary nebulae in Gaia EDR3: Central star identification, properties, and binarity|year=2021|last1=González-Santamaría|first1=I.|last2=Manteiga|first2=M.|last3=Manchado|first3=A.|last4=Ulla|first4=A.|last5=Dafonte|first5=C.|last6=López Varela|first6=P.|journal=Astronomy & Astrophysics|volume=656|pages=A51|arxiv=2109.12114|bibcode=2021A&A...656A..51G|s2cid=237940344}}
