1156.0. "Where's Perseus?" by REGENT::BROOMHEAD (Don't panic -- yet.) Wed Aug 11 1993 13:58
Just for fun, here's how to find Perseus, the constellation out of
which the Perseid meteor showers are supposed to come. (Paradoxically,
if the display is worth watching, you won't need these directions.)
In theory, we can all recognize the Big Dipper:
*
* * *
*
* *
(or something like that -- this is from memory)
Most of us were told how to find the North Star (a.k.a. the Pole Star,
and the tip of the Little Dipper, and the Little Bear): You sight
along the pointer stars of the Big Dipper and there it is:
*
distance <x>
^
|
* |
* * *
|
* |
* *
at some distance <x>. (If you go the wrong way, you go two or three
times as far, then you encounter the reverse question mark of Leo.)
To find the region of Perseus, use the other star that forms the
bottom of the dipper, and the same top star, and go twice the distance
of <x>:
*
distance <x>
^
^ / distance 2<x>

Happy celestial navigating!
