The catalogued J2000 position is carried along the great circle the object's own published motion puts it on, at a constant velocity, and the result is referred to the true equator and equinox of this instant. Those are separate things: the motion moves the object, and the rotation turns the grid under it by about fifty arcseconds a year, with nutation adding up to another seventeen.","excluded":"Parallax, the radial-velocity perspective term, aberration and refraction; each is below the accuracy of the catalogued positions themselves. An object with no published proper motion comes back where the catalogue has it rather than at a fabricated zero, and says so with a null pm_ra_mas_yr. A body with no fixed position is not propagated at all — its place comes from an ephemeris, which is what /api/v1/visible answers with."},"slug":"ngc-6076","name":"NGC 6076","class":"galaxy_pair","category":"galaxy","object_type":"Galaxy pair","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":null,"distance_method":null,"ra_deg":242.80583333333334,"dec_deg":26.8725,"epoch_ra_deg":243.082972,"epoch_dec_deg":26.802465,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":null,"semi_major_axis_km":null,"periapsis_km":null,"mass_kg":null,"mass_msun":null,"constellation":"Corona Borealis","discovered":"1864","featured":false,"url":"https://spacecatalog.org/object/ngc-6076","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"wikidata_id":"Q1125477","discovered_by":"Albert Marth","ngc_type_code":"GPair","major_axis_arcmin":0.8},"designations":[{"catalog":"LEDA","designation":"LEDA 57409"},{"catalog":"MCG","designation":"MCG +05-38-023"},{"catalog":"NGC","designation":"NGC 6076"},{"catalog":"NGC","designation":"NGC 6076-1"},{"catalog":"PGC","designation":"PGC 57409"},{"catalog":"UGC","designation":"UGC 10253"}],"source":{"id":"openngc","name":"OpenNGC","url":"https://github.com/mattiaverga/OpenNGC","license":"CC-BY-SA-4.0"},"updated_at":"2026-08-27T19:16:43.430Z","attribution":"Data from SpaceCatalog.org.
