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-7077","name":"NGC 7077","class":"elliptical_galaxy_e","category":"galaxy","object_type":"Elliptical galaxy E","mag":13.67,"mag_band":"V","abs_mag":null,"abs_mag_band":null,"distance_ly":36779500.44451484,"distance_method":"redshift (CMB frame), flat ΛCDM with H0 = 70 km/s/Mpc","ra_deg":322.498375,"dec_deg":2.4141666666666666,"epoch_ra_deg":322.838519,"epoch_dec_deg":2.531675,"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":"Aquarius","discovered":"1863","featured":false,"url":"https://spacecatalog.org/object/ngc-7077","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":14.37,"h_mag":11.82,"j_mag":12.31,"k_mag":11.38,"v_mag":13.67,"redshift":0.003743,"hubble_type":"E","wikidata_id":"Q1149462","redshift_cmb":0.002627771817183877,"discovered_by":"Albert Marth","ngc_type_code":"G","uncertainties":{"distance_ly":[14084303.21930732,14084303.21930732]},"major_axis_arcmin":0.9,"minor_axis_arcmin":0.56,"wikipedia_article":"NGC 7077","position_angle_deg":12,"surface_brightness":23.09,"radial_velocity_km_s":1120},"designations":[{"catalog":"2MASX","designation":"2MASX J21295963+0224517"},{"catalog":"IRAS","designation":"IRAS F21274+0211"},{"catalog":"LEDA","designation":"LEDA 66860"},{"catalog":"MCG","designation":"MCG +00-54-028"},{"catalog":"MCG","designation":"MCG 0-54-28"},{"catalog":"NGC","designation":"NGC 7077"},{"catalog":"PGC","designation":"PGC 66860"},{"catalog":"UGC","designation":"UGC 11755"}],"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.
