Difference Between Stars And Planets

Stars and planets are two different celestial objects in our universe. The universe is made up of all of space, time, and everything that exists inside it, including galaxies, planets, stars, and all other types of matter and energy. Celestial bodies that are existent in distant space include both stars and planets. Both stars and planets differ from one another in a variety of ways, including size, source of energy, capacity for producing light, etc. Planets are smaller celestial things that reflect light from stars rather than producing their light and energy, whereas stars are described as large celestial bodies that create light and energy through nuclear fusion.

What are Stars?

Stars are objects which revolve independently within the universe. Stars may be defined as objects with a self-emitting light source that are created as a result of ongoing thermonuclear fusion. Nuclear fusion, which results from the transformation of hydrogen into helium and is thought to be the source of self-emitting light, is how the light is produced. They move only in accordance with their fixed place in the universe, but since their movements are so minute, no one can see them. However, if there is any movement across a significant distance, it is detected. They are quite huge and have extremely high internal temperatures. These elements are composed of the continually breaking down hydrogen and helium, as well as a few additional light atomic mass elements.

What are Planets?

Planets are additional things that are part of the universe. They may be defined as universe objects that don’t have a self-emitting source of light and proceed along an established path. The star, or sun, which is present in the solar system, serves as the planets’ source of illumination. The solar system has eight planets. These planets range in size and temperature, with the ones closest to the sun having a warm temperature and those further from it having a cold one. Depending on the name of the planet, its contents can vary, but generally speaking, liquids and gases, along with sometimes solid particles, make up the majority of these planets. 

Difference Between Stars and Planets

Basis of comparison	Stars	Planets
Definition	Celestial bodies are created by the thermonuclear fusion and have a source of light.	Celestial things rotate around stars and follow a set revolution route.
Number	One (In the solar system) and Trillions (In the galaxy).	Eight (In the solar system).
Size	The size of the star is big compared to the planet.	The size of the planet is small compared to the star.
Temperature	Stars have extremely high temperatures due to internal nuclear reactions.	Planets’ temperatures are low, and they can vary depending on how far a star is from a nearby star.
Light	They each have a source of light due to the thermonuclear fusion that took place in their core.	They don’t have a light source of their own as their source of light is the sun.
Position	The stars are so far apart that their positions change over time, and this may be observed.	As they revolve around the Sun, planets often change their positions.
Speed	High in speed as compared to the planets.	Low in speed as compared to stars.
Orbit	Each star revolves around the galaxy center.	Typically, planets in the solar system revolve around the star.
Twinkling Effect	They do twinkle.	They do not twinkle.
Matter	Hydrogen, helium, and many other light elements.	Often composed of liquid and gases, but sometimes also includes solid particles.
Period of revolution	Stars travel a great distance in their own distinct orbits, and over time, their motion may be observed.	Every planet revolves around the Sun along a certain path. This route is referred to as Orbit.
