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-6792","name":"NGC 6792","class":"barred_spiral_galaxy_sbb","category":"galaxy","object_type":"Barred spiral galaxy SBb","mag":13.29,"mag_band":"B","abs_mag":null,"abs_mag_band":null,"distance_ly":210236083.08567736,"distance_method":"redshift (CMB frame), flat ΛCDM with H0 = 70 km/s/Mpc","ra_deg":290.23920833333335,"dec_deg":43.1325,"epoch_ra_deg":290.451126,"epoch_dec_deg":43.182338,"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":"Lyra","discovered":"1886","featured":false,"url":"https://spacecatalog.org/object/ngc-6792","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":13.29,"h_mag":9.43,"j_mag":10.06,"k_mag":9.1,"redshift":0.015471,"hubble_type":"SBb","wikidata_id":"Q1147703","redshift_cmb":0.014882585459077946,"ngc_type_code":"G","uncertainties":{"distance_ly":[16479131.20824606,16479131.20824606]},"major_axis_arcmin":2.08,"minor_axis_arcmin":1.11,"position_angle_deg":24,"surface_brightness":23.14,"radial_velocity_km_s":4602},"designations":[{"catalog":"2MASX","designation":"2MASX J19205740+4307572"},{"catalog":"IRAS","designation":"IRAS 19193+4302"},{"catalog":"IRAS","designation":"IRAS F19193+4302"},{"catalog":"LEDA","designation":"LEDA 63096"},{"catalog":"MCG","designation":"MCG +07-40-002"},{"catalog":"NGC","designation":"NGC 6792"},{"catalog":"PGC","designation":"PGC 63096"},{"catalog":"UGC","designation":"UGC 11429"}],"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.
