The night sky is always have been a fascination for many people as many heavenly bodies can be found in the sky during this time. The planets, stars, comets, asteroids, constellations are some of the bodies that are found.
Although these are situated many light years away from the Earth and appear to be tiny objects with naked eyes despite being large.
Stars vs Planets
The main difference between Star and Planet is that the stars can be observed with a special phenomenon that is twinkling with naked eyes whereas comparatively, on the other hand, the planets don’t show this, and along with it, they cannot be observed through naked eyes. Stars sometimes show a pattern which is known as the constellation, which is not observed by planets.
Star is an object that is distinguished as an astronomical object within the universe and has its very own source of emission of light. In other words, they don’t need any other source to show luminance.
Also, they don’t change their position of themselves, but if they, it is due to some massive cause.
Planets are an important part of the universe as the mother earth is also among one of the examples of the planet other than the rest seven which are – Mercury, Mars, Venus, Neptune, Jupiter, Uranus, and Saturn.
They used to move around the sun in the solar system but on their fixed position and way stated as ‘’orbit’’.
Comparison Table Between Stars and Planets
|Parameters of Comparison||Stars||Planets|
|Definition||Heavenly objects possess their source of light and are formed by the thermonuclear fusion||Heavenly objects possess a fixed revolutionary path and revolve around stars|
|Light||Own source||Sun is the source|
|Position||They don’t change it but only in certain large distance||They often change it|
|Matter||Light elements, Hydrogen, Helium, and many other||Often made up of liquid, and gases, sometimes with solid particles too|
|Number (in solar system)||1||8|
|Revolution Period||Fixed and unnoticeable||Fixed path|
What are Stars?
Stars are the objects that revolve in the universe within themselves. In simple terms, the stars can be stated as the objects that have a self-emitting source of light and are formed because of the continuous thermonuclear fusion.
The light source that is said to be self comes from nuclear fusion, and that occurs because of the conversion taking place from hydrogen to helium, and that is what emits the light.
They have a fixed position in the universe, and they also move with that only, but the movement is much small because of which it is not get noticed. But if any large distance movement takes place, it gets noticed.
They have a very large size and have very high temperatures within them. The constituents of these are hydrogen, helium which break down continuously and along with it some other elements with light atomic masses.
What are Planets?
Planets are other objects that are also members of the universe. In simple terms, they can be stated as the objects of the universe which don’t have a self-emitting source of light and move around a fixed path.
The light source achieved by the planets is from the star that is the sun present in the solar system.
In the solar system, the total number of planets is eight, and they are – Mercury, Mars, Venus, Neptune, Jupiter, Uranus, and Saturn. Out Mother Earth is the eighth planet on the list and is the only planet suitable for life.
The size of these planets varies accordingly, so as their temperature, the planets that are near to the sun have a warm temperature and the ones away from the sun are cold.
The constituents of these planets are different depending on their name, but the main ones are – liquid and gases and sometimes have solid particles.
Main Differences Between Stars and Planets
- Stars can be stated as the heavenly objects that are present in the universe having with own light source and formed by the thermonuclear fusion, whereas comparatively, on the other hand, the Planets can be stated as the heavenly body that revolves in a fixed path around the star.
- The light source of stars is present on their own, whereas comparatively, on the other hand, the light source of the planet comes from the star that is Sun. In other words, they don’t have their self-light source.
- The position of the stars is normally unnoticeable as they don’t change it, but when they move to a considerable distance, it is noticeable, whereas comparatively, on the other hand, the position of the planets is often changing because they revolve on their axis and around the star.
- The size of the star in the universe tends to appear quite big, whereas comparatively, on the other hand, the size of the planets in the universe appears to be small.
- The temperature possessed by a star is very high, whereas comparatively, on the other hand, the temperature of any planet can be high or low but never as high as a star.
- Star shows an extraordinary effect or phenomenon that is known as the twinkling effect, whereas comparatively, on the other hand, planets are the bodies that don’t show any such phenomenon.
- The composition of the stars includes many elements that have light atomic masses, with hydrogen and helium, whereas comparatively, on the other hand, the composition of the planets differ according to their name although the main constituents are – liquid and gases, and sometimes they have solid particles too.
- In the solar system, only one star is present, and that is Sun, whereas comparatively, on the other hand, in the solar system, there are eight total planets.
- Stars have a dot-shaped whereas comparatively, on the other hand, the planets have a sphere-shaped size.
- The revolution period of the star is fixed, but it is unnoticeable, whereas comparatively, on the other hand, the revolution period of the planets is also fixed, and the specific term used for it is ‘orbit.’
To summarize the above discussion, the universe is full of many mysteries and astronomical objects that are known and unknown to scientists. Some of these objects possess light but still, some don’t have.
Some of the objects with light are – sun, stars, and moon, while some of the objects with no light are – planets, comets, asteroids, etc.
The most noticeable difference between the above terms – stars and planets is the occurrence of a special phenomenon known as the ‘’twinkling of stars’’.
The size of these astronomical objects also does vary as stars tend to be large while planets are small compared to them.
Same as their temperature, stars have quite high temperatures while the temperature of planets may vary from high to cold, but they are always less than the stars.
