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-27269","name":"PGC 27269","class":"lenticular_galaxy","category":"galaxy","object_type":"Lenticular galaxy","mag":15.348,"mag_band":"B","abs_mag":-19.32788043292915,"abs_mag_band":"B","distance_ly":280932485.6583933,"distance_method":"luminosity distance from a spectroscopic redshift (GLADE+), flat ΛCDM with H0 = 70 km/s/Mpc","ra_deg":143.870972,"dec_deg":34.9865,"epoch_ra_deg":144.277505,"epoch_dec_deg":34.866826,"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":null,"featured":false,"url":"https://spacecatalog.org/object/pgc-27269","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":15.348,"h_mag":11.632,"j_mag":12.342,"k_mag":11.407,"redshift":0.02126,"hubble_type":"-2","redshift_cmb":0.0198143420611094,"uncertainties":{"distance_ly":[14908265.144737938,14912982.715131866],"stellar_mass_solar":[2802431473.262814,2802431473.262814]},"major_axis_arcmin":0.746813,"minor_axis_arcmin":0.486848,"morphology_source":"SIMBAD (2010ApJS..186..427N, quality D)","position_angle_deg":128,"stellar_mass_solar":24287739434.94439},"designations":[{"catalog":"2MASX","designation":"2MASX 09352903+3459114"},{"catalog":"PGC","designation":"PGC 27269"},{"catalog":"WISExSCOS","designation":"WISExSCOS J093529.03+345911.8"}],"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.
