It has a Jupiter-like planet. Not a "hot Jupiter" (a ~ 0.1 AU): the figure I seem to recall is a = 3.3 AU. I don't recall the eccentricity. Guess I'll have to look it up. 16 Cygni B, a well-known solar analogue (though possibly not as close as 18 Scorpii, which was described this week as a near-twin of the Sun) has a Jupiter-like planet whose orbit does cross from the equivalent of near the orbit of Venus to outside the orbit of Mars.
