thanks captin blal
the best one of the collection to me is alcor and mizar
coz when i was a child (9 years) i was looking to ursa major very much
and first i saw just one star it was alcor, after two weeks a saw they are two stars not one!!!!
by the naked aye
and i was so conffused about that when i grow up after 5 years i have the first program which seen you the sky
and then i realized that what i saw was something real
and now i know why i saw at first one then i saw two
coz of this two stars

we know that alcor and mizar are not a binary system
they are an optical binary
but mizar contain a four stars-system
and i think at the first the star mizar was so bright
so i cant see the another star(alcor)
but after some weeks i see the tow stars
coz the bright of mizar down coz of his four star system and them rotations
so i think mizar is a varibale star changing from time to time
and thats it all

capt.bilal

well done nasser , that was pretty good answer
