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-6132","name":"NGC 6132","class":"spiral_galaxy_sab","category":"galaxy","object_type":"Spiral galaxy Sab","mag":14.71,"mag_band":"B","abs_mag":null,"abs_mag_band":null,"distance_ly":237561555.44811696,"distance_method":"redshift (CMB frame), flat ΛCDM with H0 = 70 km/s/Mpc","ra_deg":245.91183333333333,"dec_deg":11.786249999999999,"epoch_ra_deg":246.227872,"epoch_dec_deg":11.723454,"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":"Hercules","discovered":"1876","featured":false,"url":"https://spacecatalog.org/object/ngc-6132","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":14.71,"h_mag":11.18,"j_mag":11.86,"k_mag":10.95,"redshift":0.01657,"hubble_type":"Sab","wikidata_id":"Q1125939","redshift_cmb":0.016793013816781777,"discovered_by":"Édouard Stephan","ngc_type_code":"G","uncertainties":{"distance_ly":[17087732.981515918,17087732.981515918]},"major_axis_arcmin":1.28,"minor_axis_arcmin":0.43,"position_angle_deg":127,"surface_brightness":23.39,"radial_velocity_km_s":4926},"designations":[{"catalog":"2MASX","designation":"2MASX J16233880+1147109"},{"catalog":"IC","designation":"IC 4602"},{"catalog":"IRAS","designation":"IRAS 16213+1153"},{"catalog":"IRAS","designation":"IRAS F16212+1154"},{"catalog":"LEDA","designation":"LEDA 58002"},{"catalog":"MCG","designation":"MCG +02-42-002"},{"catalog":"NGC","designation":"NGC 6132"},{"catalog":"PGC","designation":"PGC 58002"},{"catalog":"SDSS","designation":"SDSS J162338.83+114710.4"},{"catalog":"SDSS","designation":"SDSS J162338.84+114710.4"},{"catalog":"SDSS","designation":"SDSS J162338.84+114710.5"},{"catalog":"UGC","designation":"UGC 10363"}],"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.
