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":"ic-3832","name":"IC 3832","class":"barred_spiral_galaxy_sbc","category":"galaxy","object_type":"Barred spiral galaxy SBc","mag":16.17,"mag_band":"B","abs_mag":null,"abs_mag_band":null,"distance_ly":504655999.0092601,"distance_method":"redshift (CMB frame), flat ΛCDM with H0 = 70 km/s/Mpc","ra_deg":192.705,"dec_deg":39.81047222222222,"epoch_ra_deg":193.023218,"epoch_dec_deg":39.664236,"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":"Canes Venatici","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/ic-3832","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":16.17,"redshift":0.03441,"hubble_type":"SBc","wikidata_id":"Q3685310","redshift_cmb":0.03519476897152285,"ngc_type_code":"G","uncertainties":{"distance_ly":[24884061.395134576,24884061.395134576]},"major_axis_arcmin":0.46,"minor_axis_arcmin":0.39,"position_angle_deg":72,"surface_brightness":23.28,"radial_velocity_km_s":10138},"designations":[{"catalog":"IC","designation":"IC 3832"},{"catalog":"LEDA","designation":"LEDA 43482"},{"catalog":"MCG","designation":"MCG +07-26-057"},{"catalog":"PGC","designation":"PGC 43482"},{"catalog":"SDSS","designation":"SDSS J125049.19+394837.7"},{"catalog":"SDSS","designation":"SDSS J125049.20+394837.7"}],"source":{"id":"openngc","name":"OpenNGC","url":"https://github.com/mattiaverga/OpenNGC","license":"CC-BY-SA-4.0"},"updated_at":"2026-09-01T22:58:55.274Z","attribution":"Data from SpaceCatalog.org.
