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-7196","name":"NGC 7196","class":"elliptical_galaxy_e","category":"galaxy","object_type":"Elliptical galaxy E","mag":12.01,"mag_band":"V","abs_mag":null,"abs_mag_band":null,"distance_ly":128308229.38852859,"distance_method":"redshift (CMB frame), flat ΛCDM with H0 = 70 km/s/Mpc","ra_deg":331.47837499999997,"dec_deg":-50.11933333333334,"epoch_ra_deg":331.909457,"epoch_dec_deg":-49.988817,"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":"Indus","discovered":"1834","featured":false,"url":"https://spacecatalog.org/object/ngc-7196","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":12.37,"h_mag":8.59,"j_mag":9.23,"k_mag":8.27,"v_mag":12.01,"redshift":0.009767,"hubble_type":"E","wikidata_id":"Q1150117","redshift_cmb":0.009122244269588187,"discovered_by":"John Frederick William Herschel","ngc_type_code":"G","uncertainties":{"distance_ly":[14994285.463912841,14994285.463912841]},"major_axis_arcmin":2.76,"minor_axis_arcmin":2.06,"wikipedia_article":"NGC 7196","position_angle_deg":59,"surface_brightness":23.43,"radial_velocity_km_s":2914},"designations":[{"catalog":"2MASX","designation":"2MASX J22055480-5007094"},{"catalog":"ESO","designation":"ESO 237-036"},{"catalog":"ESO","designation":"ESO 237-36"},{"catalog":"ESO-LV","designation":"ESO-LV 237-0360"},{"catalog":"IRAS","designation":"IRAS 22026-5021"},{"catalog":"IRAS","designation":"IRAS F22027-5021"},{"catalog":"LEDA","designation":"LEDA 68020"},{"catalog":"NGC","designation":"NGC 7196"},{"catalog":"PGC","designation":"PGC 68020"}],"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.
