Description

I was actually after the member star, -3 which includes exoplanet NGC 2423-3b seen in this section of the simbad catalog: http://simbad.u-strasbg.fr/simbad/sim-id?Ident=TYC%205409-2156-1

See the notes for the link to the encyclopedia. The star with the planet is in the Tycho catalog and I think in using the Tycho list in my planetarium software, #CartesDuCiel has the wrong coordinates for the 'mean of the date, the Astrometric J2000 is accurate, but it's off by such a large number:
