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":"ic-405","name":"Flaming Star Nebula","class":"nebula","category":"nebula","object_type":"Nebula","mag":10,"mag_band":"B","abs_mag":null,"abs_mag_band":null,"distance_ly":null,"distance_method":null,"ra_deg":79.12283333333333,"dec_deg":34.35616666666667,"epoch_ra_deg":79.566967,"epoch_dec_deg":34.386085,"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":"Auriga","discovered":"1892","featured":false,"url":"https://spacecatalog.org/object/ic-405","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":10,"wikidata_id":"Q841306","discovered_by":"John Martin Schaeberle","ngc_type_code":"Neb","major_axis_arcmin":50,"minor_axis_arcmin":30,"wikipedia_article":"IC 405"},"designations":[{"catalog":"Caldwell","designation":"C 31"},{"catalog":"Common name","designation":"Flaming Star Nebula"},{"catalog":"IC","designation":"IC 405"},{"catalog":"LBN","designation":"LBN 795"},{"catalog":"Lynds","designation":"LBN 172.16-02.02"}],"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.
