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-286-063","name":"ESO 286-063","class":"spiral_galaxy","category":"galaxy","object_type":"Spiral galaxy","mag":13.37,"mag_band":"B","abs_mag":-19.234022251543564,"abs_mag_band":"B","distance_ly":108200763.55290002,"distance_method":"luminosity distance from a spectroscopic redshift (GLADE+), flat ΛCDM with H0 = 70 km/s/Mpc","ra_deg":317.468231,"dec_deg":-45.527611,"epoch_ra_deg":317.916595,"epoch_dec_deg":-45.418538,"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":"Indus","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/eso-286-063","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":13.37,"h_mag":11.127,"j_mag":11.713,"k_mag":10.83,"redshift":0.00738318369159,"hubble_type":"3.0","redshift_cmb":0.0077009251833616,"uncertainties":{"distance_ly":[7050688.606728235,7051104.6734113805],"stellar_mass_solar":[560529014.0257432,560529014.0257432]},"major_axis_arcmin":1.45209,"minor_axis_arcmin":0.769461,"morphology_source":"SIMBAD (1989ESOLV.C......0L, quality D)","position_angle_deg":44,"stellar_mass_solar":1214479530.3891103},"designations":[{"catalog":"2MASX","designation":"2MASX 21095237-4531393"},{"catalog":"PGC","designation":"PGC 66236"},{"catalog":"WISExSCOS","designation":"WISExSCOS J210952.38-453139.1"}],"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.
