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":"pgc025886","name":"PGC025886","class":"intermediate_spiral_galaxy_sabb","category":"galaxy","object_type":"Intermediate spiral galaxy SABb","mag":11.52,"mag_band":"V","abs_mag":null,"abs_mag_band":null,"distance_ly":102889213.89912984,"distance_method":"redshift (CMB frame), flat ΛCDM with H0 = 70 km/s/Mpc","ra_deg":137.70608333333334,"dec_deg":-8.890694444444444,"epoch_ra_deg":138.034006,"epoch_dec_deg":-8.99998,"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":"Hydra","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/pgc025886","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":11.93,"h_mag":8.04,"j_mag":8.75,"k_mag":7.7,"v_mag":11.52,"redshift":0.00625,"hubble_type":"SABb","redshift_cmb":0.007324967398476101,"ngc_type_code":"G","uncertainties":{"distance_ly":[14654506.631103735,14654506.631103735]},"major_axis_arcmin":5.75,"minor_axis_arcmin":0.83,"position_angle_deg":30,"surface_brightness":23.17,"radial_velocity_km_s":1868},"designations":[{"catalog":"2MASX","designation":"2MASX J09104945-0853265"},{"catalog":"IRAS","designation":"IRAS 09083-0841"},{"catalog":"MCG","designation":"MCG -01-24-001"},{"catalog":"OpenNGC","designation":"PGC025886"},{"catalog":"UGCA","designation":"UGCA 150"}],"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.
