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-2369792","name":"PGC 2369792","class":"elliptical_galaxy_debc","category":"galaxy","object_type":"Elliptical galaxy dEbc","mag":16.59,"mag_band":"B","abs_mag":-16.61735724432305,"abs_mag_band":"B","distance_ly":142855617.92496607,"distance_method":"luminosity distance from a photometric redshift (GLADE+), flat ΛCDM with H0 = 70 km/s/Mpc","ra_deg":186.368134,"dec_deg":50.328918,"epoch_ra_deg":186.694496,"epoch_dec_deg":50.180128,"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":"Canes Venatici","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/pgc-2369792","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":16.59,"h_mag":14.686,"j_mag":15.196,"k_mag":14.456,"redshift":0.00887838443919,"hubble_type":"dEbc","redshift_cmb":0.0101486677559958,"uncertainties":{"distance_ly":[25922612.543669987,25987141.80007966],"stellar_mass_solar":[186840121.26746783,186840121.26746783]},"major_axis_arcmin":0.368157,"minor_axis_arcmin":0.239523,"morphology_source":"SIMBAD (2015ApJS..217...27A, quality C)","position_angle_deg":139,"stellar_mass_solar":373680242.53493565},"designations":[{"catalog":"2MASX","designation":"2MASX 12252835+5019441"},{"catalog":"PGC","designation":"PGC 2369792"},{"catalog":"WISExSCOS","designation":"WISExSCOS J122528.37+501943.7"}],"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.
