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-3410","name":"UGC 3410","class":"spiral_galaxy_sb","category":"galaxy","object_type":"Spiral galaxy Sb","mag":13.466,"mag_band":"B","abs_mag":-20.330528303494155,"abs_mag_band":"B","distance_ly":187383581.69720283,"distance_method":"luminosity distance from a spectroscopic redshift (GLADE+), flat ΛCDM with H0 = 70 km/s/Mpc","ra_deg":93.623413,"dec_deg":80.449852,"epoch_ra_deg":94.855085,"epoch_dec_deg":80.441103,"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":"Camelopardalis","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/ugc-3410","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":13.466,"h_mag":9.854,"j_mag":10.72,"k_mag":9.425,"redshift":0.01308,"hubble_type":"Sb","redshift_cmb":0.0132807541539077,"uncertainties":{"distance_ly":[10971851.23042791,10973340.866527038],"stellar_mass_solar":[9341822179.597065,9341822179.597065]},"major_axis_arcmin":1.37,"minor_axis_arcmin":0.411,"morphology_source":"SIMBAD (2003A&A...412...45P, quality E)","position_angle_deg":120,"stellar_mass_solar":28025466538.791195},"designations":[{"catalog":"2MASX","designation":"2MASX 06142961+8026594"},{"catalog":"PGC","designation":"PGC 18711"},{"catalog":"WISExSCOS","designation":"WISExSCOS J061429.73+802659.2"}],"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.
