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-1119651","name":"PGC 1119651","class":"irregular_galaxy_im_bcd","category":"galaxy","object_type":"Irregular galaxy Im/BCD","mag":16.87,"mag_band":"B","abs_mag":-15.43737529020132,"abs_mag_band":"B","distance_ly":94384555.14746433,"distance_method":"luminosity distance from a photometric redshift (GLADE+), flat ΛCDM with H0 = 70 km/s/Mpc","ra_deg":175.817,"dec_deg":-1.3947,"epoch_ra_deg":176.160827,"epoch_dec_deg":-1.543709,"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":"Virgo","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/pgc-1119651","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":16.87,"redshift":0.00585228292614,"hubble_type":"Im/BCD","redshift_cmb":0.0067225562149171,"uncertainties":{"distance_ly":[17415278.08329766,17442764.516767118],"stellar_mass_solar":[18684415.12988582,18684415.12988582]},"major_axis_arcmin":0.360737,"minor_axis_arcmin":0.22225,"morphology_source":"SIMBAD (2015ApJS..217...27A, quality C)","position_angle_deg":90,"stellar_mass_solar":37368830.25977164},"designations":[{"catalog":"PGC","designation":"PGC 1119651"},{"catalog":"WISExSCOS","designation":"WISExSCOS J114316.03-012341.2"}],"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":"2026-09-02T19:50:56.720Z","attribution":"Data from SpaceCatalog.org.
