Actually, this seems to be in line with what I've followed in the more
technical (but still popular) astronomy press... planetary orbits in the
intense interactions in a the early solar system were very unstable. IIRC,
the biggest planet tends to move inward as it tends to eject objects that
lie inward from it, but I'm not sure I recall the disequilibrium condition
that causes this. The presence of "hot jovians" in other solar systems,
circling their stars in only days in orbits far smaller than Mercury's,
shows that planatary evolution can be quite, er, dynamic.
At least the BBC article didn't say that Jupiter gave birth to *Venus* :)
