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-7386","name":"NGC 7386","class":"lenticular_galaxy_s0","category":"galaxy","object_type":"Lenticular galaxy S0","mag":12.52,"mag_band":"V","abs_mag":null,"abs_mag_band":null,"distance_ly":325618007.67293173,"distance_method":"redshift (CMB frame), flat ΛCDM with H0 = 70 km/s/Mpc","ra_deg":342.50895833333334,"dec_deg":11.698361111111112,"epoch_ra_deg":342.84339,"epoch_dec_deg":11.840436,"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":"Pegasus","discovered":"1784","featured":false,"url":"https://spacecatalog.org/object/ngc-7386","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":13.52,"h_mag":9.66,"j_mag":10.39,"k_mag":9.42,"v_mag":12.52,"redshift":0.024167,"hubble_type":"S0","wikidata_id":"Q1167310","redshift_cmb":0.022913464728858912,"discovered_by":"William Herschel","ngc_type_code":"G","uncertainties":{"distance_ly":[19346865.32441293,19346865.32441293]},"major_axis_arcmin":2.04,"minor_axis_arcmin":1.3,"position_angle_deg":144,"surface_brightness":23.79,"radial_velocity_km_s":7158},"designations":[{"catalog":"2MASX","designation":"2MASX J22500213+1141555"},{"catalog":"LEDA","designation":"LEDA 69825"},{"catalog":"MCG","designation":"MCG +02-58-018"},{"catalog":"NGC","designation":"NGC 7386"},{"catalog":"PGC","designation":"PGC 69825"},{"catalog":"UGC","designation":"UGC 12209"}],"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.
