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":"ngc6076-ned01","name":"NGC6076 NED01","class":"galaxy","category":"galaxy","object_type":"Galaxy","mag":15.31,"mag_band":"B","abs_mag":null,"abs_mag_band":null,"distance_ly":481600062.49539727,"distance_method":"redshift (CMB frame), flat ΛCDM with H0 = 70 km/s/Mpc","ra_deg":242.80420833333335,"dec_deg":26.872027777777777,"epoch_ra_deg":243.08151,"epoch_dec_deg":26.80197,"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":null,"featured":false,"url":"https://spacecatalog.org/object/ngc6076-ned01","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":15.31,"h_mag":11.03,"j_mag":11.73,"k_mag":10.73,"redshift":0.0334,"wikidata_id":"Q76838599","redshift_cmb":0.033625107506505714,"ngc_type_code":"G","uncertainties":{"distance_ly":[24121445.07225585,24121445.07225585]},"major_axis_arcmin":1,"minor_axis_arcmin":0.46,"position_angle_deg":62,"surface_brightness":23.9,"radial_velocity_km_s":9847},"designations":[{"catalog":"2MASX","designation":"2MASX J16111299+2652195"},{"catalog":"MCG","designation":"MCG +05-38-023 NED01"},{"catalog":"NGC","designation":"NGC 6076A"},{"catalog":"NGC","designation":"NGC 6076SW"},{"catalog":"OpenNGC","designation":"NGC6076 NED01"},{"catalog":"UGC","designation":"UGC 10253 NED01"}],"source":{"id":"openngc","name":"OpenNGC","url":"https://github.com/mattiaverga/OpenNGC","license":"CC-BY-SA-4.0"},"updated_at":"2026-09-02T19:50:56.720Z","attribution":"Data from SpaceCatalog.org.
