What is the Difference between a planet and a Star?

A planet is a Celestial Body that is illuminated by sunlight, a celestial body is something that can bee seen in the sky or outer space to Earth, planets are massive enough to have their own gravity.

In the Solar System every planet orbits the Sun in the same direction as the Sun rotates.

Stars have their own source of Light.

A star is a massive, luminous ball of plasma that is held together by gravity. The nearest star to Earth is the Sun which is also a star.a star shines due to thermonuclear fusion in its core releasing energy from the star's interior and radiates into outer space.

Stars form in the densest regions of molecular clouds as a result of gravitational instabilities caused mainly by supernovae or collisions of galaxies.

In a general sense, we can say that a star is all celestial body that shines with its own source of light.

With this being said, now we can understand the main difference between a planet and a star, is the fact that some are bright and some not, but what causes stars to radiate Light?, The starlight is the result of large amounts of energy that their bodies release gas indeed huge concentrations of gas.

A normal star parts are; core, mantle and atmosphere. The core is where nuclear reactions occur which generate their energy. The mantle heats energy that is transported toward the surface and depending on how the transport by convection or radiation, will be divided into two zones: radiant and convective.

Finally, the atmosphere is the most superficial of the stars and the only one is visible.

 Another question we can ask ourselves is can we distinguish with the naked eye, watching the night sky, planets of stars? … No, it is very difficult to distinguish with the naked eye (not to say that is simply not possible), since they are too far and can not distinguish whether they are bodies visible by its own light or receiving of a nearby star, this simply means that you can not distinguish wether if a planet or a star is being illuminated by a nearby celestial body.

The nearest star to the Sun, a little over 4.2 light years, is known as Proxima Centauri. A little further, to 4.3 light years, found a set of stars named “Alpha Centauri”. Beyond this, almost 6 light years, lies the “Barnard’s Star.”
