Simply typed in: "Do the constellations change "

I found this on one of the sites.

... A more typical proper motion is about 0.1 arcsecs/year, which would move the typical star about 1 degree in 42,000 years - that's still 2 times the size of the full moon so would make a fairly noticeable change to the familiar constellations. ...

I will leave it to you to figure out the change in 4566 years.

Please remember of course that stars are all moving in different directions. Gives you a new respect for Starry Night doesn't it ?

In other words to figure out what a constellation looked like 4566 years ago you would need to know the direction each star is moving in and it's speed. Quite a homework assignment this time.

Speaking of Starry Night maybe someone can run this problem through it. We need to see the skies over Cairo on a couple of different occasions. Let's try 11,500 Bc, 10,450 BC, 8,000 BC 3100 BC 2560 BC and the present and of course focus on Cygnus.

Cheers
