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":"pgc-982467","name":"PGC 982467","class":"spiral_galaxy_sc","category":"galaxy","object_type":"Spiral galaxy Sc","mag":16.005,"mag_band":"B","abs_mag":-18.85560708036098,"abs_mag_band":"B","distance_ly":305877330.4928127,"distance_method":"luminosity distance from a spectroscopic redshift (GLADE+), flat ΛCDM with H0 = 70 km/s/Mpc","ra_deg":14.500497,"dec_deg":-10.093328,"epoch_ra_deg":14.838174,"epoch_dec_deg":-9.948157,"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":"Cetus","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/pgc-982467","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":16.005,"h_mag":14.215,"j_mag":14.913,"k_mag":13.698,"redshift":0.01942,"hubble_type":"Sc","redshift_cmb":0.0215460785122919,"uncertainties":{"distance_ly":[15395942.59567351,15399426.418711185],"stellar_mass_solar":[653893555.1093088,653893555.1093088]},"major_axis_arcmin":0.678647,"minor_axis_arcmin":0.211127,"morphology_source":"SIMBAD (2006A&A...445..765K, quality D)","position_angle_deg":128,"stellar_mass_solar":1401200475.2342331},"designations":[{"catalog":"2MASX","designation":"2MASX 00580011-1005359"},{"catalog":"PGC","designation":"PGC 982467"},{"catalog":"WISExSCOS","designation":"WISExSCOS J005800.14-100535.9"}],"source":{"id":"glade_plus","name":"GLADE+ (Galaxy List for the Advanced Detector Era)","url":"https://cdsarc.cds.unistra.fr/viz-bin/cat/VII/291","license":"VizieR terms; cite Dalya+ 2022 (2022MNRAS.514.1403D)"},"updated_at":"2026-08-30T09:56:50.739Z","attribution":"Data from SpaceCatalog.org.
