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":"ngc-3119","name":"NGC 3119","class":"elliptical_galaxy_e","category":"galaxy","object_type":"Elliptical galaxy E","mag":14.14,"mag_band":"B","abs_mag":null,"abs_mag_band":null,"distance_ly":null,"distance_method":null,"ra_deg":151.716125,"dec_deg":14.373527777777777,"epoch_ra_deg":152.078867,"epoch_dec_deg":14.242667,"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":"Leo","discovered":"1863","featured":false,"url":"https://spacecatalog.org/object/ngc-3119","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":14.14,"h_mag":9.94,"j_mag":10.63,"k_mag":9.62,"redshift":0.00057,"hubble_type":"E","wikidata_id":"Q4044867","redshift_cmb":0.0016725618960304889,"discovered_by":"Albert Marth","ngc_type_code":"G","major_axis_arcmin":1.05,"minor_axis_arcmin":0.81,"position_angle_deg":20,"surface_brightness":23.11,"radial_velocity_km_s":171},"designations":[{"catalog":"2MASX","designation":"2MASX J10065190+1422247"},{"catalog":"LEDA","designation":"LEDA 29381"},{"catalog":"LEDA","designation":"LEDA 29387"},{"catalog":"MCG","designation":"MCG +03-26-027 NED01"},{"catalog":"NGC","designation":"NGC 3119"},{"catalog":"NGC","designation":"NGC 3121"},{"catalog":"PGC","designation":"PGC 29381"},{"catalog":"PGC","designation":"PGC 29387"},{"catalog":"SDSS","designation":"SDSS J100651.86+142224.8"},{"catalog":"SDSS","designation":"SDSS J100651.87+142224.8"},{"catalog":"UGC","designation":"UGC 5450"}],"source":{"id":"openngc","name":"OpenNGC","url":"https://github.com/mattiaverga/OpenNGC","license":"CC-BY-SA-4.0"},"updated_at":"2026-09-02T19:50:56.720Z","attribution":"Data from SpaceCatalog.org.
