An naoú réalta is gile sa spéir san oíche, agus an dara réalta is gile i réaltbhuíon Oríon (nó an Bhodaigh) is ea Betelgeuse, ar a dtugtar freisin, de réir ainmniú Bayer, Alfa Orionis (α Orionis, α Ori). De gnáth, ní bhíonn sé níos gile ná a chomharsa Rigel (Beta Orionis). Is réalta athraitheach leathrialta é agus athraíonn a mhéid idir 0.2 agus 1.2. Bíonn dath scothdhearg ar leighligh aige. Marcáileann an réalta an rinn uachtarach ar dheis sa Triantán Geimhridh agus lár an Heicseagáin Gheimhridh.
