Encyclopedic overview
NGC 3206 is a barred spiral galaxy in the constellation of Ursa Major. Its velocity with respect to the cosmic microwave background is 1309 ± 11 km/s, which corresponds to a Hubble distance of 19.31 ± 1.36 Mpc (~63 million light-years). In addition, 11 non redshift measurements give a distance of 17.582 ± 1.088 Mpc (~57.3 million light-years). The galaxy was discovered by German-British astronomer William Herschel on 8 April 1793.
According to the SIMBAD database, NGC 3206 is an Active Galaxy Nucleus Candidate, i.e. it has a compact region at the center of a galaxy that emits a significant amount of energy across the electromagnetic spectrum, with characteristics indicating that this luminosity is not produced by the stars.
