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":"ugc-2614","name":"UGC 2614","class":"spiral_galaxy_sa_r","category":"galaxy","object_type":"Spiral galaxy Sa(R)","mag":13.56,"mag_band":"B","abs_mag":-20.90022746350821,"abs_mag_band":"B","distance_ly":254373208.48849848,"distance_method":"luminosity distance from a spectroscopic redshift (GLADE+), flat ΛCDM with H0 = 70 km/s/Mpc","ra_deg":48.824593,"dec_deg":42.696278,"epoch_ra_deg":49.271934,"epoch_dec_deg":42.796087,"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":"Perseus","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/ugc-2614","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":13.56,"h_mag":10.049,"j_mag":10.76,"k_mag":9.721,"redshift":0.0176162788081,"hubble_type":"Sa(R)","redshift_cmb":0.0179657341762567,"uncertainties":{"distance_ly":[30588410.708119094,30589718.19791598],"stellar_mass_solar":[5604928002.436792,5604928002.436792]},"major_axis_arcmin":1.48,"minor_axis_arcmin":0.474,"morphology_source":"SIMBAD (2020A&A...640A..30M, quality C)","position_angle_deg":90,"stellar_mass_solar":44839424019.49434},"designations":[{"catalog":"2MASX","designation":"2MASX 03151790+4241466"},{"catalog":"PGC","designation":"PGC 12092"},{"catalog":"WISExSCOS","designation":"WISExSCOS J031517.95+424146.8"}],"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":"2026-09-02T19:50:56.720Z","attribution":"Data from SpaceCatalog.org.
