This is a basic star table.
More information is available here.
Choose your star from these tables and you will have some of the numbers that you need for your solar system and your planet. Our sun is a G2 star. As we found out from our hands-on activity, our sun formed 4.5 billion years ago. Earth also formed about 4.5 billion years ago, and 3.2 billion years ago, or perhaps even earlier, the first single celled life forms appeared. When you consider that the earth had to cool from a molten state first, life seems to have appeared quite quickly.
