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":"eso-084-026","name":"ESO 084-026","class":"lenticular_galaxy","category":"galaxy","object_type":"Lenticular galaxy","mag":13.828,"mag_band":"B","abs_mag":-20.782223546034988,"abs_mag_band":"B","distance_ly":272565311.9051939,"distance_method":"luminosity distance from a spectroscopic redshift (GLADE+), flat ΛCDM with H0 = 70 km/s/Mpc","ra_deg":69.081757,"dec_deg":-65.141098,"epoch_ra_deg":69.12654,"epoch_dec_deg":-65.08561,"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":"Dorado","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/eso-084-026","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":13.828,"h_mag":10.118,"j_mag":10.831,"k_mag":9.844,"redshift":0.01834,"hubble_type":"-1.0","redshift_cmb":0.0192324965152273,"uncertainties":{"distance_ly":[14356155.83760401,14359300.361591762],"stellar_mass_solar":[7473177778.136147,7473177778.136147]},"major_axis_arcmin":1.561,"minor_axis_arcmin":0.46752,"morphology_source":"SIMBAD (1989ESOLV.C......0L, quality D)","position_angle_deg":102,"stellar_mass_solar":58851275002.82215},"designations":[{"catalog":"2MASX","designation":"2MASX 04361962-6508279"},{"catalog":"PGC","designation":"PGC 15622"},{"catalog":"WISExSCOS","designation":"WISExSCOS J043619.64-650827.9"}],"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.
