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-2010","name":"IC 2010","class":"intermediate_spiral_galaxy_saba","category":"galaxy","object_type":"Intermediate spiral galaxy SABa","mag":13.71,"mag_band":"V","abs_mag":null,"abs_mag_band":null,"distance_ly":249102708.96580213,"distance_method":"redshift (CMB frame), flat ΛCDM with H0 = 70 km/s/Mpc","ra_deg":57.99179166666667,"dec_deg":-59.929361111111106,"epoch_ra_deg":58.119199,"epoch_dec_deg":-59.848313,"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":"Reticulum","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/ic-2010","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":14.38,"h_mag":11.16,"j_mag":11.85,"k_mag":10.85,"v_mag":13.71,"redshift":0.01768,"hubble_type":"SABa","wikidata_id":"Q3692664","redshift_cmb":0.01759829899621801,"ngc_type_code":"G","uncertainties":{"distance_ly":[17359332.955943733,17359332.955943733]},"major_axis_arcmin":1.19,"minor_axis_arcmin":0.48,"position_angle_deg":71,"surface_brightness":23.07,"radial_velocity_km_s":5254},"designations":[{"catalog":"2MASX","designation":"2MASX J03515803-5955459"},{"catalog":"ESO","designation":"ESO 117-011"},{"catalog":"ESO","designation":"ESO 117-11"},{"catalog":"ESO-LV","designation":"ESO-LV 117-0110"},{"catalog":"IC","designation":"IC 2010"},{"catalog":"IRAS","designation":"IRAS 03510-6004"},{"catalog":"IRAS","designation":"IRAS F03510-6004"},{"catalog":"LEDA","designation":"LEDA 13995"},{"catalog":"PGC","designation":"PGC 13995"}],"source":{"id":"openngc","name":"OpenNGC","url":"https://github.com/mattiaverga/OpenNGC","license":"CC-BY-SA-4.0"},"updated_at":"2026-08-30T09:56:50.739Z","attribution":"Data from SpaceCatalog.org.
