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-3265","name":"NGC 3265","class":"elliptical_galaxy_e","category":"galaxy","object_type":"Elliptical galaxy E","mag":13.54,"mag_band":"V","abs_mag":null,"abs_mag_band":null,"distance_ly":80516893.45765375,"distance_method":"redshift (CMB frame), flat ΛCDM with H0 = 70 km/s/Mpc","ra_deg":157.77820833333334,"dec_deg":28.796666666666667,"epoch_ra_deg":158.154237,"epoch_dec_deg":28.658925,"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":"Leo Minor","discovered":"1785","featured":false,"url":"https://spacecatalog.org/object/ngc-3265","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":14.05,"h_mag":10.68,"j_mag":11.37,"k_mag":10.44,"v_mag":13.54,"redshift":0.00475,"hubble_type":"E","wikidata_id":"Q1103929","redshift_cmb":0.005739097386888048,"discovered_by":"William Herschel","ngc_type_code":"G","uncertainties":{"distance_ly":[14409096.388821688,14409096.388821688]},"major_axis_arcmin":0.97,"minor_axis_arcmin":0.71,"position_angle_deg":73,"surface_brightness":22.83,"radial_velocity_km_s":1421},"designations":[{"catalog":"2MASX","designation":"2MASX J10310676+2847470"},{"catalog":"IRAS","designation":"IRAS 10282+2903"},{"catalog":"IRAS","designation":"IRAS F10283+2903"},{"catalog":"LEDA","designation":"LEDA 31029"},{"catalog":"MCG","designation":"MCG +05-25-019"},{"catalog":"NGC","designation":"NGC 3265"},{"catalog":"PGC","designation":"PGC 31029"},{"catalog":"SDSS","designation":"SDSS J103106.76+284747.9"},{"catalog":"SDSS","designation":"SDSS J103106.77+284748.0"},{"catalog":"UGC","designation":"UGC 5705"}],"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.
