Answer #1

Cas A (Cassiopeia A)  is a supernova remnant in the constellation Cassiopeia. The information that Sun has about the same abundance  of iron in it as Cas A shows that our Sun is also formed by supernova remnant. Age of our Sun is 4.6 billion years while the age of our galaxy is about 8 billion years which shows that one of big star died and during supernova remnant of it condense to form our Sun and solar system.

I will be glad to see your comment if you have any query and thumb up if you are satisfied. Thanks....
