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-45367","name":"PGC 45367","class":"barred_spiral_galaxy_sbcr","category":"galaxy","object_type":"Barred spiral galaxy SBcr","mag":14.405,"mag_band":"B","abs_mag":-20.062289113917856,"abs_mag_band":"B","distance_ly":255201779.28546032,"distance_method":"luminosity distance from a spectroscopic redshift (GLADE+), flat ΛCDM with H0 = 70 km/s/Mpc","ra_deg":196.59256,"dec_deg":-1.681014,"epoch_ra_deg":196.937849,"epoch_dec_deg":-1.824808,"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":"Virgo","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/pgc-45367","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":14.405,"h_mag":11.841,"j_mag":12.562,"k_mag":11.596,"redshift":0.01837,"hubble_type":"SBcr","redshift_cmb":0.0180234804569865,"uncertainties":{"distance_ly":[13949964.412888473,13953215.093205078],"stellar_mass_solar":[2802463014.7664022,2802463014.7664022]},"major_axis_arcmin":1.14693,"minor_axis_arcmin":0.764885,"morphology_source":"SIMBAD (2010AJ....139.2525H, quality D)","position_angle_deg":74,"stellar_mass_solar":5604926029.5328045},"designations":[{"catalog":"2MASX","designation":"2MASX 13062221-0140516"},{"catalog":"PGC","designation":"PGC 45367"},{"catalog":"WISExSCOS","designation":"WISExSCOS J130622.25-014052.2"}],"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.
