NGC 6217 is a barred spiral galaxy located some 67 million light years away, in the constellation Ursa Minor. It can be located with a 10 cm (4 in) or larger telescope as an 11th magnitude object about 2.5° east-northeast of the star Zeta Ursae Minoris. The galaxy is inclined by an angle of 33° to the line of sight along a position angle of 162°.
A morphological classification of (R')SB(rs)bc indicates that NGC 6217 has a false outer ring-like structure formed from the spiral arms (R'), a well-defined bar running across the nucleus (SB), a partial inner ring (rs), and moderately-wound spiral arms (bc). The nucleus is spherical in shape, showing no indication of oblateness. The prominent bar spans an angular distance of 48″ (48 arc seconds) across the galaxy along a position angle of 35.97° ± 0.35°. At 10″ southeast of the nucleus is a prominent region of star formation. The inner ring is about 43″.5 across.
