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-93089","name":"PGC 93089","class":"barred_spiral_galaxy_sb","category":"galaxy","object_type":"Barred spiral galaxy SB","mag":14.842,"mag_band":"B","abs_mag":-20.530857382368545,"abs_mag_band":"B","distance_ly":387255283.4410102,"distance_method":"luminosity distance from a photometric redshift (GLADE+), flat ΛCDM with H0 = 70 km/s/Mpc","ra_deg":111.683815,"dec_deg":37.385506,"epoch_ra_deg":112.134349,"epoch_dec_deg":37.331872,"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":"Auriga","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/pgc-93089","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":14.842,"h_mag":12.961,"j_mag":13.612,"k_mag":12.66,"redshift":0.02695,"hubble_type":"SB","redshift_cmb":0.0271657336392141,"uncertainties":{"distance_ly":[79749544.11398849,80338036.80744573],"stellar_mass_solar":[3736402629.570281,3736402629.570281]},"major_axis_arcmin":0.98939,"minor_axis_arcmin":0.337877,"morphology_source":"SIMBAD (quality D)","position_angle_deg":19,"stellar_mass_solar":6538704601.747992},"designations":[{"catalog":"2MASX","designation":"2MASX 07264411+3723078"},{"catalog":"PGC","designation":"PGC 93089"},{"catalog":"WISExSCOS","designation":"WISExSCOS J072644.02+372308"}],"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":"2026-09-01T22:58:55.274Z","attribution":"Data from SpaceCatalog.org.
