Explanation:
Detailed explanation-1: -The sun is made up of a blazing combination of gases. These gases are actually in the form of plasma. Plasma is a state of matter similar to gas, but with most of the particles ionized. This means the particles have an increased or reduced number of electrons.
Detailed explanation-2: -Scientists use spectroscopy to determine the composition of the Sun. Unlike the Earth, the Sun is made primarily of light elements. It is a fairly typical main sequence star composed of 74% hydrogen, 25% helium.
Detailed explanation-3: -12. Which action would most likely happen to the motion of the planets without the force of gravity from the sun? The planets would begin to move in straight lines.
