NGC 5861 is an active barred spiral galaxy with extensive star formation from Hubble type SBc in the constellation Libra on the ecliptic . It is estimated to be 82 million light years away from the Milky Way and has a diameter of about 75,000 ly. In the same area of the sky there are u. a. the galaxies NGC 5858 , NGC 5872 , IC 1091 .
In this galaxy the supernovae SN 1971D and SN 2017erp were observed.
The object was discovered on May 9, 1784 by Wilhelm Herschel with an 18.7-inch reflector telescope, who described it as “pF, pL, slightly extended nearly along the meridian”.
