Difference Between Stars and Planets

It is essential to know the key differences between Stars and Planets as they are both celestial bodies located in outer space. It is important to understand the clear distinctions between a star and a planet, a star is a body that possesses a light which causes it to reflect the light on its own. A planet on the other hand, is simply a celestial body that is fixed and has its own orbit and spins on its own axis, yet reflects the light from an external source. As planets do not have an internal source of light, they only receive light from external sources primarily the Sun. Minkowski space is usually used to calculate for special relativity problems, to obtain solutions.

One of the major key points that differentiates stars from planets is size. Even though through images planets may look gigantic and stars may look distant and small, in reality stars are gigantic when compared to planets. For a full comparison between planets and stars check out the table below.

Difference between Stars and Planets



Stars are incredibly hot having high temperatures to them.

Planets on the other hand have relatively low temperatures.

They are objects that produce their own light and do not rely on an external source for the production of light

Planets are incapable of producing their own light.

Stars have a unique effect of twinkling in the sky.

Planets do not exhibit the twinkling effect unlike stars

The stars do not change their position at all.

Planets in orbits on their own axis change their positions constantly.

Stars have incredibly high temperatures to them.

Planets on the other hand are relatively colder with lower temperatures.

Thus, this is the basic difference between stars and planets. If you liked this article then download the BYJU’s app today! You may also want to check out the related links below.
