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":"pgc-402085","name":"PGC 402085","class":"galaxy","category":"galaxy","object_type":"Galaxy","mag":17.08,"mag_band":"B","abs_mag":-16.036584419372765,"abs_mag_band":"B","distance_ly":137007000.71454385,"distance_method":"luminosity distance from a photometric redshift (GLADE+), flat ΛCDM with H0 = 70 km/s/Mpc","ra_deg":130.894,"dec_deg":-56.21344,"epoch_ra_deg":131.066785,"epoch_dec_deg":-56.309719,"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":"Carina","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/pgc-402085","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":17.08,"h_mag":12.897,"j_mag":13.828,"k_mag":12.55,"redshift":0.00904134452067,"redshift_cmb":0.0097361940306547,"uncertainties":{"distance_ly":[26876939.59556998,26942659.173842188],"stellar_mass_solar":[467101516.62582934,467101516.62582934]},"stellar_mass_solar":840782729.9264928},"designations":[{"catalog":"2MASX","designation":"2MASX 08433474-5612488"},{"catalog":"PGC","designation":"PGC 402085"}],"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":"2026-09-01T22:58:55.274Z","attribution":"Data from SpaceCatalog.org.
