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-7185","name":"NGC 7185","class":"elliptical_galaxy_e_s0","category":"galaxy","object_type":"Elliptical galaxy E-S0","mag":12.58,"mag_band":"V","abs_mag":null,"abs_mag_band":null,"distance_ly":70923674.75605492,"distance_method":"redshift (CMB frame), flat ΛCDM with H0 = 70 km/s/Mpc","ra_deg":330.73645833333336,"dec_deg":-20.471277777777775,"epoch_ra_deg":331.108177,"epoch_dec_deg":-20.341793,"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":"Aquarius","discovered":"1830","featured":false,"url":"https://spacecatalog.org/object/ngc-7185","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":13.41,"h_mag":9.78,"j_mag":10.48,"k_mag":9.69,"v_mag":12.58,"redshift":0.006108,"hubble_type":"E-S0","wikidata_id":"Q598660","redshift_cmb":0.005057918950457818,"discovered_by":"John Frederick William Herschel","ngc_type_code":"G","uncertainties":{"distance_ly":[14319950.626760224,14319950.626760224]},"major_axis_arcmin":2.31,"minor_axis_arcmin":1.61,"position_angle_deg":26,"surface_brightness":23.96,"radial_velocity_km_s":1826},"designations":[{"catalog":"2MASX","designation":"2MASX J22025674-2028165"},{"catalog":"ESO","designation":"ESO 601-010"},{"catalog":"ESO","designation":"ESO 601-10"},{"catalog":"ESO-LV","designation":"ESO-LV 601-0100"},{"catalog":"LEDA","designation":"LEDA 67919"},{"catalog":"MCG","designation":"MCG -04-52-011"},{"catalog":"NGC","designation":"NGC 7185"},{"catalog":"PGC","designation":"PGC 67919"}],"source":{"id":"openngc","name":"OpenNGC","url":"https://github.com/mattiaverga/OpenNGC","license":"CC-BY-SA-4.0"},"updated_at":"2026-08-27T19:16:43.430Z","attribution":"Data from SpaceCatalog.org.
