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-6112","name":"NGC 6112","class":"elliptical_galaxy_e","category":"galaxy","object_type":"Elliptical galaxy E","mag":14.87,"mag_band":"B","abs_mag":null,"abs_mag_band":null,"distance_ly":450636566.7805586,"distance_method":"redshift (CMB frame), flat ΛCDM with H0 = 70 km/s/Mpc","ra_deg":244.50233333333333,"dec_deg":35.11027777777778,"epoch_ra_deg":244.752155,"epoch_dec_deg":35.044149,"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":"Corona Borealis","discovered":"1880","featured":false,"url":"https://spacecatalog.org/object/ngc-6112","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":14.87,"h_mag":11.01,"j_mag":11.64,"k_mag":10.71,"redshift":0.03136,"hubble_type":"E","wikidata_id":"Q1125774","redshift_cmb":0.03151165150379365,"discovered_by":"Édouard Stephan","ngc_type_code":"G","uncertainties":{"distance_ly":[23116377.723099828,23116377.723099828]},"major_axis_arcmin":0.78,"minor_axis_arcmin":0.73,"position_angle_deg":135,"surface_brightness":23.2,"radial_velocity_km_s":9254},"designations":[{"catalog":"2MASX","designation":"2MASX J16180057+3506367"},{"catalog":"LEDA","designation":"LEDA 57762"},{"catalog":"MCG","designation":"MCG +06-36-017"},{"catalog":"NGC","designation":"NGC 6112"},{"catalog":"PGC","designation":"PGC 57762"},{"catalog":"SDSS","designation":"SDSS J161800.56+350637.0"},{"catalog":"SDSS","designation":"SDSS J161800.57+350637.0"}],"source":{"id":"openngc","name":"OpenNGC","url":"https://github.com/mattiaverga/OpenNGC","license":"CC-BY-SA-4.0"},"updated_at":"2026-08-27T19:16:43.430Z","attribution":"Data from SpaceCatalog.org.
