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-625","name":"NGC 625","class":"barred_spiral_galaxy_sbm","category":"galaxy","object_type":"Barred spiral galaxy SBm","mag":13.66,"mag_band":"V","abs_mag":null,"abs_mag_band":null,"distance_ly":null,"distance_method":null,"ra_deg":23.769291666666668,"dec_deg":-41.43619444444444,"epoch_ra_deg":24.061827,"epoch_dec_deg":-41.298607,"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":"Phoenix","discovered":"1826","featured":false,"url":"https://spacecatalog.org/object/ngc-625","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":11.65,"h_mag":9.09,"j_mag":9.66,"k_mag":8.9,"v_mag":13.66,"redshift":0.00132,"hubble_type":"SBm","wikidata_id":"Q1037752","redshift_cmb":0.0006735279554439533,"discovered_by":"James Dunlop","ngc_type_code":"G","major_axis_arcmin":6.55,"minor_axis_arcmin":2.05,"wikipedia_article":"NGC 625","position_angle_deg":92,"surface_brightness":23.43,"radial_velocity_km_s":395},"designations":[{"catalog":"2MASX","designation":"2MASX J01350463-4126103"},{"catalog":"ESO","designation":"ESO 297-005"},{"catalog":"ESO","designation":"ESO 297-5"},{"catalog":"ESO-LV","designation":"ESO-LV 297-0050"},{"catalog":"IRAS","designation":"IRAS 01329-4141"},{"catalog":"IRAS","designation":"IRAS F01329-4141"},{"catalog":"LEDA","designation":"LEDA 5896"},{"catalog":"MCG","designation":"MCG -07-04-017"},{"catalog":"NGC","designation":"NGC 625"},{"catalog":"PGC","designation":"PGC 5896"}],"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.
