Difference Between Planets and Stars

Stars and planets are two different types of astronomical objects that can be found in the universe . Both objects are made up of different elements and also vary in appearance, size, and even “behavior.”

Although few would mistake a star for a planet, the truth is that not everyone would know how to explain their differences; For this reason, this time we have decided to explain everything about what is the difference between stars and planets. If you have doubts about it or are simply looking for a little more information to complement what you already know, keep reading, because below you will find everything you need around this interesting topic that they have probably already left you of homework for school.

PLANET  Difference Between Stars and Planets

A planet is a large astronomical object that orbits around a star or stellar debris. This mainly due to its own force of gravity and the gravity of the star that is close to it. In general, the shape of the orbit of the planets is elliptical; but it depends on how the gravitational force of the planet and its star acts.

The gravitational force of a planet is strong enough so that it can maintain its rounded shape, that is, so that the compounds of its matter can concentrate in a spherical shape. Likewise, planets tend to “clean up” debris found in the regions near them; either absorbing them, pushing them or turning them into satellites (in case they have a considerable gravitational force, as for example: the case of the Earth and the Moon).


On the other hand, stars are giant, luminous plasma spheres that remain intact in their shape thanks to their gravitational force of attraction.

The planets revolve around the stars. A clear example is our planet Earth revolves around the sun . Most of the stars that have so far been observed in the universe are much larger than the Sun. Some even up to a thousand times larger.

The stars are the main source of energy for the planets and although due to their immense distance they may seem like small dots in the sky, some are so huge that they stand out to the degree that humans have managed to group them into constellations.

Stars are generally composed to a greater extent of two gases: hydrogen and helium. Unlike the planets that are made of rocks and minerals. At their centers, stars contain atomic energy that is constantly used to create nuclear fusion; reaction that results in the immense amount of light and heat that these stars emit.

Finally, there are many types of stars: white dwarfs, neutron stars, blue stars, red dwarfs, supergiant’s, hypergiants.
