Is it possible to find where a constellation was positioned in the sky on a certain date?

Question

or are they always the same? what web sites can you recommend for finding this type of information?

Answer 1

If you are talking about a recent date, they don't change from year to year.  The changes are only significant over a thousand years or more.

Tell us what constellation and what year.  You will also need the time of day.  Constellations go all the way around each 24 hours.

Answer 2

You need a device called a Planisphere.  This is a moving cardboard/plastic diagram that you can set for any date and time, and it will show you the positions of the stars and constellations at that time.

Just do an internet search on "planisphere."  You will also get links to some internet sites that do the same thing on the screen.  I prefer the old type of planisphere, because the batteries never need to be replaced.

Have fun.
