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-26","name":"NGC 26","class":"spiral_galaxy_sab","category":"galaxy","object_type":"Spiral galaxy Sab","mag":13.84,"mag_band":"B","abs_mag":null,"abs_mag_band":null,"distance_ly":200040768.10170937,"distance_method":"redshift (CMB frame), flat ΛCDM with H0 = 70 km/s/Mpc","ra_deg":2.6077916666666665,"dec_deg":25.831833333333332,"epoch_ra_deg":2.954197,"epoch_dec_deg":25.981239,"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":"Pegasus","discovered":"1865","featured":false,"url":"https://spacecatalog.org/object/ngc-26","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":13.84,"h_mag":10.69,"j_mag":11.42,"k_mag":10.42,"redshift":0.015317,"hubble_type":"Sab","wikidata_id":"Q34848","redshift_cmb":0.014168417963376312,"discovered_by":"Heinrich Louis d'Arrest","ngc_type_code":"G","uncertainties":{"distance_ly":[16265301.959585153,16265301.959585153]},"major_axis_arcmin":1.12,"minor_axis_arcmin":0.76,"wikipedia_article":"NGC 26","position_angle_deg":102,"surface_brightness":22.8,"radial_velocity_km_s":4557},"designations":[{"catalog":"2MASX","designation":"2MASX J00102587+2549544"},{"catalog":"IRAS","designation":"IRAS 00078+2533"},{"catalog":"IRAS","designation":"IRAS F00078+2533"},{"catalog":"LEDA","designation":"LEDA 732"},{"catalog":"MCG","designation":"MCG +04-01-034"},{"catalog":"NGC","designation":"NGC 26"},{"catalog":"PGC","designation":"PGC 732"},{"catalog":"UGC","designation":"UGC 94"}],"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.
