Pretty Planets all in a Row

This week and next, weather permitting, we have a rare view of all the planets lined up in an arc across the southern sky just after dark. Don't miss it! Mercury is low in the southwest just after sunset. Above and to the left are reddish Mars and bright Venus. Jupiter is the bright star high in the south, and Saturn is in the southeast. You can't see Neptune, Uranus, and Pluto without help, but they are also in the sky, along with the crescent Moon. It's surprising that all the planets are in the sky at once, but it's not surprising that they are all in a line. Why?
