Question

This is a massive ball of plasma that shines because of thermonuclear fusion in its core.

Answer 1

A star is an astronomical object that consists of a luminous spheroid of plasma held together by its own gravity. 

A star is also a massive ball of plasma that shines because of thermonuclear fusion in its core. A portion of its life, a star shines due to thermonuclear fusion of hydrogen into helium in its core, releasing energy that traverses through the interior and eventually radiates to the outer space.

Answer 2

Answer:

Star

Explanation:

Star

A star is massive ball of plasma that shines because of  the thermonuclear fusion in its core. A star is luminous object that has energy of its own. Fusion of hydrogen atom into a helium atom release a tremendous amount of energy. Hence, the temperature and pressure inside of a star rises to such level that the gases are ionized to form fourth state of matter called Plasma.
