That may be true of small bodies like comets, Laird, but Venus is not, and never was, a comet - which is what you're hinting at here in mentioning Velikovsky and objects flying out of Jupiter. There's nothing in standard astronomy to suggest Venus formed at any other time than with the rest of the planets.
Based on recent studies of exo-planets, it's completely within the realm of possibility that Venus had a comet-like tail (in fact, still has a remnant ion tail), and that it might have formed at a different time than other planets.
