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-2694","name":"NGC 2694","class":"elliptical_galaxy_e","category":"galaxy","object_type":"Elliptical galaxy E","mag":14.14,"mag_band":"V","abs_mag":null,"abs_mag_band":null,"distance_ly":247792775.98439896,"distance_method":"redshift (CMB frame), flat ΛCDM with H0 = 70 km/s/Mpc","ra_deg":134.24691666666666,"dec_deg":51.33197222222223,"epoch_ra_deg":134.726141,"epoch_dec_deg":51.228818,"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":"Ursa Major","discovered":"1850","featured":false,"url":"https://spacecatalog.org/object/ngc-2694","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":15.18,"h_mag":11.39,"j_mag":12.08,"k_mag":11.46,"v_mag":14.14,"redshift":0.016978,"hubble_type":"E","wikidata_id":"Q1050349","redshift_cmb":0.017506945892591164,"discovered_by":"William Parsons, 3rd Earl of Rosse","ngc_type_code":"G","uncertainties":{"distance_ly":[17328093.03810335,17328093.03810335]},"major_axis_arcmin":0.81,"minor_axis_arcmin":0.5,"position_angle_deg":177,"surface_brightness":23.56,"radial_velocity_km_s":5047},"designations":[{"catalog":"2MASX","designation":"2MASX J08565924+5119544"},{"catalog":"LEDA","designation":"LEDA 25143"},{"catalog":"MCG","designation":"MCG +09-15-056"},{"catalog":"NGC","designation":"NGC 2694"},{"catalog":"PGC","designation":"PGC 25143"},{"catalog":"SDSS","designation":"SDSS J085659.25+511955.0"},{"catalog":"SDSS","designation":"SDSS J085659.25+511955.3"},{"catalog":"SDSS","designation":"SDSS J085659.26+511955.0"},{"catalog":"SDSS","designation":"SDSS J085659.26+511955.1"},{"catalog":"UGC","designation":"UGC 04674 NOTES01"}],"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.
