NGC 3568 is a barred spiral galaxy in the constellation of Centaurus. Its velocity with respect to the cosmic microwave background is , which corresponds to a Hubble distance of . However, 25 non-redshift measurements give a much closer mean distance of . It was discovered by British astronomer John Herschel on 21 April 1835.
NGC 3568 is a Seyfert I galaxy, i.e. it has a quasar-like nucleus with very high surface brightnesses whose spectra reveal strong, high-ionisation emission lines, but unlike quasars, the host galaxy is clearly detectable.
NGC 3557 group NGC 3568 is a member of the NGC 3557 group (also known as LGG 229) which has at least 11 galaxies, including , NGC 3557, , , and , among others.
Supernova One supernova has been observed in NGC 3568: SN 2014dw (TypeII, mag. 15.5) was discovered by Stu Parker on 6 November 2014.
