 By;Wilson Lucky.

WHAT IS A STAR?
 Star is a huge ball of gas held together by gravity. The central core of a star is extremely hot and produces energy. Some of this energy is released as visible light, which makes the star glow.

DIFFERENTIATE BETWEEN A STAR,PLANET AND MOON RESPECTIVELY.
 The difference between a Star,Planet and Moon is considered in fact that the star is an independed celestial body,The Planet depends on their star in the cause of it's orbits While a Moon is a natural satalite that reflect light through the star and it orbits a planet.
In otherwords, the Earth orbits the star,while the Moon orbits the Earth.
The Moon orbits around the Earth, but as the Earth orbits the Sun, the Moon also orbits the Sun, while following the Earth.
