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-835","name":"NGC 835","class":"spiral_galaxy_sab","category":"galaxy","object_type":"Spiral galaxy Sab","mag":12.41,"mag_band":"V","abs_mag":null,"abs_mag_band":null,"distance_ly":184815583.37679455,"distance_method":"redshift (CMB frame), flat ΛCDM with H0 = 70 km/s/Mpc","ra_deg":32.3525,"dec_deg":-10.135916666666667,"epoch_ra_deg":32.682571,"epoch_dec_deg":-10.00864,"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":"Cetus","discovered":"1785","featured":false,"url":"https://spacecatalog.org/object/ngc-835","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":13.16,"h_mag":9.28,"j_mag":9.95,"k_mag":8.95,"v_mag":12.41,"redshift":0.013947,"hubble_type":"Sab","wikidata_id":"Q1039599","redshift_cmb":0.013100515509786748,"discovered_by":"William Herschel","ngc_type_code":"G","uncertainties":{"distance_ly":[15960317.580199694,15960317.580199694]},"major_axis_arcmin":0.87,"minor_axis_arcmin":0.73,"position_angle_deg":5,"surface_brightness":21.5,"radial_velocity_km_s":4152},"designations":[{"catalog":"2MASX","designation":"2MASX J02092458-1008091"},{"catalog":"IRAS","designation":"IRAS 02069-1022"},{"catalog":"IRAS","designation":"IRAS F02069-1022"},{"catalog":"LEDA","designation":"LEDA 8228"},{"catalog":"MCG","designation":"MCG -02-06-031"},{"catalog":"NGC","designation":"NGC 835"},{"catalog":"NGC","designation":"NGC 838W"},{"catalog":"PGC","designation":"PGC 8228"},{"catalog":"SDSS","designation":"SDSS J020924.60-100809.3"}],"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.
