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-349-007","name":"ESO 349-007","class":"spiral_galaxy","category":"galaxy","object_type":"Spiral galaxy","mag":16.33,"mag_band":"B","abs_mag":-17.194223718182585,"abs_mag_band":"B","distance_ly":165299149.42679656,"distance_method":"luminosity distance from a photometric redshift (GLADE+), flat ΛCDM with H0 = 70 km/s/Mpc","ra_deg":359.048,"dec_deg":-33.30633,"epoch_ra_deg":359.395165,"epoch_dec_deg":-33.156771,"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":"Sculptor","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/eso-349-007","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":16.33,"redshift":0.0114951957476,"hubble_type":"9.0","redshift_cmb":0.0117291562380332,"uncertainties":{"distance_ly":[33368882.142686997,33477705.393975843],"stellar_mass_solar":[65393392.36481463,65393392.36481463]},"major_axis_arcmin":0.78,"minor_axis_arcmin":0.37,"morphology_source":"SIMBAD (1989ESOLV.C......0L, quality D)","position_angle_deg":20,"stellar_mass_solar":112102958.33968222},"designations":[{"catalog":"PGC","designation":"PGC 72935"},{"catalog":"WISExSCOS","designation":"WISExSCOS J235611.64-331823"}],"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.
