Venus
In Block 13 of the Contact Notes in German (page 2542): On the 238th contact, 18th May, 1991, Ptaah told Billy that there existed a planet circling the Sun where today Venus has its orbit. It was a planet called "Skill" (as called by the Plejaran). It was 6,100 kilometres in diameter, which is roughly half the size of Earth. Earth is 12,756.2 kilometres. Skill collided with the Destroyer Comet and was hurled into SOL, our sun. Skill means "Oede" in German, that in English means: "waste, desolateness, barrenness, deserted). [1]
Venus in contact 31 is flown past in a beamship when Billy jokes about photographing a Venusian, which spurs a conversation about fraudulent contactees, because no one lives there. Its another desolate and uninhabitable planet.[2]
