B' e Bhèineas neo Rìbhinn an darna planaid. Is i an rud as dearrsach san speur againne as deidh, an Grian agus an Gealach, agus tha far-ainm aice - "a' Mhadainneag". 'S e Bhèineas am planaid as fhaisge dhuinn. Chan eil saideal aice.
Ràinig na Sovietich Bhèineas sa chiad aite, leis na proban "Venera". chunnaic iad àile geur is garbh, agus talamh teth. Cha do mhair na proban ach mionaidean. Gu mi-fhortanach, cha bidh daoine a' fuireach ann a dh'aithghearr, agus gun teagamh, chan eil beatha sam bith air an talamh aige.
Bha ceangail làidir eadar Bheineas agus Quetzacoatl, agus chleachd na Comunnaich i, mar seorsa seun, m.e. b' e The Morning Star, pàipear-naidheachd Comunnach.
