There's only one star in the solar system....the sun!

There are no planetary alignments (other than the annual alignment between the sun, the earth and the approximate centre of the galaxy that occurs every December). Various planetary alignments occurred in 1962, 1982 and 2000 but there's nothing of any significance over the next couple of decades, and even if there was it would have no noticable effect on the earth.

I'm planning to go to a party on 22nd, myself!
