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":"ngc-5080","name":"NGC 5080","class":"lenticular_galaxy_s0","category":"galaxy","object_type":"Lenticular galaxy S0","mag":14.32,"mag_band":"B","abs_mag":null,"abs_mag_band":null,"distance_ly":320486973.5755422,"distance_method":"redshift (CMB frame), flat ΛCDM with H0 = 70 km/s/Mpc","ra_deg":199.83008333333333,"dec_deg":8.429138888888888,"epoch_ra_deg":200.166972,"epoch_dec_deg":8.287865,"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":"Virgo","discovered":"1881","featured":false,"url":"https://spacecatalog.org/object/ngc-5080","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":14.32,"h_mag":10.2,"j_mag":10.84,"k_mag":9.96,"redshift":0.02153,"hubble_type":"S0","wikidata_id":"Q1116828","redshift_cmb":0.02255831014158316,"discovered_by":"Edward S.
