What is the significance of the Sun being a second-generation star?
Answer
It indicates the Sun formed from remnants enriched by previous stellar deaths
Because the early universe contained only hydrogen and helium, the Sun's status as a second-generation star confirms that its material makeup includes heavy elements seeded by long-dead, earlier stars.
