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-3832","name":"NGC 3832","class":"spiral_galaxy_sc","category":"galaxy","object_type":"Spiral galaxy Sc","mag":12.94,"mag_band":"V","abs_mag":null,"abs_mag_band":null,"distance_ly":342713329.5846034,"distance_method":"redshift (CMB frame), flat ΛCDM with H0 = 70 km/s/Mpc","ra_deg":175.881,"dec_deg":22.72544444444444,"epoch_ra_deg":176.230309,"epoch_dec_deg":22.57646,"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":"Leo","discovered":"1785","featured":false,"url":"https://spacecatalog.org/object/ngc-3832","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":13.69,"h_mag":10.86,"j_mag":11.4,"k_mag":10.11,"v_mag":12.94,"redshift":0.02301,"hubble_type":"Sc","wikidata_id":"Q1106715","redshift_cmb":0.024095444112044007,"discovered_by":"William Herschel","ngc_type_code":"G","uncertainties":{"distance_ly":[19829184.005504593,19829184.005504593]},"major_axis_arcmin":1.87,"minor_axis_arcmin":1.51,"position_angle_deg":7,"surface_brightness":23.62,"radial_velocity_km_s":6819},"designations":[{"catalog":"2MASX","designation":"2MASX J11433138+2243316"},{"catalog":"IRAS","designation":"IRAS 11409+2300"},{"catalog":"IRAS","designation":"IRAS F11409+2300"},{"catalog":"LEDA","designation":"LEDA 36446"},{"catalog":"MCG","designation":"MCG +04-28-040"},{"catalog":"NGC","designation":"NGC 3832"},{"catalog":"PGC","designation":"PGC 36446"},{"catalog":"SDSS","designation":"SDSS J114331.43+224331.5"},{"catalog":"SDSS","designation":"SDSS J114331.43+224331.6"},{"catalog":"SDSS","designation":"SDSS J114331.44+224331.6"},{"catalog":"UGC","designation":"UGC 6693"}],"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.
