Answer 2

Explanation:

The Sun is by far the largest object in the solar system. It contains more than 99.8% of the total mass of the Solar System.The Sun is personified in many mythologies: the Greeks called it Helios and the Romans called it Sol.

The Sun is, at present, about 70% hydrogen and 28% helium by mass everything else (“metals”) amounts to less than 2%. This changes slowly over time as the Sun converts hydrogen to helium in its core.
