NGC 5681 is a spiral galaxy in the constellation of Boötes. Its velocity with respect to the cosmic microwave background is 8,164±16 km/s, which corresponds to a Hubble distance of 392.7 ± 27.5 Mly (120.41 ± 8.43 Mpc).[1] However, two non-redshift measurements give a closer distance of 331.21 ± 89.53 Mly (101.550 ± 27.450 Mpc).[2] It was discovered by German astronomer Heinrich d'Arrest on 1 May 1865.[3]
NGC 5681 is a radio galaxy, i.e. it has giant regions of radio emission extending well beyond its visible structure.[4]
