What is a Star?
A large sphere of burning gas in the universe can be seen as a small spot of light in the night sky. A star is a body that has a light that reflects light independently. Stars begin their life cycle as clouds of gas and dust called nebulae and evolve into increasingly hot and dense protostars through gravity and accretion.
Star radiates energy, in particular, light and infrared radiation, that usually originates from an internal thermonuclear reaction and, in some cases, is emitted as ultraviolet, radio, or X-rays. The surface temperature can range from approximately 2100 to 40,000° C.
There is no proper count for stars. Astronomers estimate that the Milky Way alone has about 100 billion stars.
How does a planet differ from a star?
A star refers to a body that possesses a light that causes it to reflect the light independently and a planet, on the other hand, is a fixed celestial body that has its own orbit and spins on its own axis, yet also reflects the light from an, so external source. In the solar system, a very large round object in the universe orbiting the Sun or another star. A planet is a stationary celestial body in its own orbit, rotating around its own axis, but reflecting light from an external light source. Since the planet has no internal light source, the planet receives only light from the external light source, mainly the sun.
