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-105-007","name":"ESO 105-007","class":"lenticular_galaxy","category":"galaxy","object_type":"Lenticular galaxy","mag":14.011,"mag_band":"B","abs_mag":-20.216995160213695,"abs_mag_band":"B","distance_ly":228572988.86633527,"distance_method":"luminosity distance from a spectroscopic redshift (GLADE+), flat ΛCDM with H0 = 70 km/s/Mpc","ra_deg":293.729248,"dec_deg":-64.740639,"epoch_ra_deg":294.364709,"epoch_dec_deg":-64.681795,"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":"Pavo","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/eso-105-007","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":14.011,"h_mag":10.248,"j_mag":10.979,"k_mag":9.971,"redshift":0.01453,"hubble_type":"-1.0","redshift_cmb":0.0161651785656626,"uncertainties":{"distance_ly":[14008734.20211543,14010335.135369796],"stellar_mass_solar":[9341652507.34023,9341652507.34023]},"major_axis_arcmin":0.817,"minor_axis_arcmin":0.604,"morphology_source":"SIMBAD (1989ESOLV.C......0L, quality D)","position_angle_deg":55,"stellar_mass_solar":28024957522.020695},"designations":[{"catalog":"2MASX","designation":"2MASX 19345501-6444263"},{"catalog":"PGC","designation":"PGC 63383"},{"catalog":"WISExSCOS","designation":"WISExSCOS J193455.02-644426.3"}],"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.
