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-170214","name":"PGC 170214","class":"galaxy","category":"galaxy","object_type":"Galaxy","mag":14.65,"mag_band":"B","abs_mag":-19.209815553485967,"abs_mag_band":"B","distance_ly":192925211.88900203,"distance_method":"luminosity distance from a spectroscopic redshift (GLADE+), flat ΛCDM with H0 = 70 km/s/Mpc","ra_deg":193.482727,"dec_deg":-9.118806,"epoch_ra_deg":193.832164,"epoch_dec_deg":-9.264625,"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-170214","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":14.65,"h_mag":11.494,"j_mag":12.182,"k_mag":11.244,"redshift":0.01416,"redshift_cmb":0.0136695382614496,"uncertainties":{"distance_ly":[12150562.443373086,12152269.267152907],"stellar_mass_solar":[934179924.806127,934179924.806127]},"stellar_mass_solar":11210159097.673525},"designations":[{"catalog":"2MASX","designation":"2MASX 12535585-0907077"},{"catalog":"PGC","designation":"PGC 170214"},{"catalog":"WISExSCOS","designation":"WISExSCOS J125355.86-090707.8"}],"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.
