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-125297","name":"PGC 125297","class":"spiral_galaxy_s","category":"galaxy","object_type":"Spiral galaxy S","mag":15.71,"mag_band":"B","abs_mag":-18.649621096260987,"abs_mag_band":"B","distance_ly":242856702.82207587,"distance_method":"luminosity distance from a photometric redshift (GLADE+), flat ΛCDM with H0 = 70 km/s/Mpc","ra_deg":36.149654,"dec_deg":-41.384811,"epoch_ra_deg":36.417759,"epoch_dec_deg":-41.262847,"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":"Phoenix","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/pgc-125297","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":15.71,"h_mag":14.05,"j_mag":14.961,"k_mag":14.086,"redshift":0.0161252780626,"hubble_type":"S","redshift_cmb":0.0171626008255779,"uncertainties":{"distance_ly":[47352765.3034777,47564722.50742722],"stellar_mass_solar":[653911577.1562372,653911577.1562372]},"major_axis_arcmin":0.551523,"minor_axis_arcmin":0.396325,"morphology_source":"SIMBAD (1996MNRAS.278.1025L, quality D)","position_angle_deg":94,"stellar_mass_solar":1120991275.124978},"designations":[{"catalog":"2MASX","designation":"2MASX 02243591-4123053"},{"catalog":"PGC","designation":"PGC 125297"},{"catalog":"WISExSCOS","designation":"WISExSCOS J022435.84-412305.9"}],"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":"2026-09-02T19:50:56.720Z","attribution":"Data from SpaceCatalog.org.
