Round or Not: The Shape of Planets and Stars Explained

In summary, the planet and star are all approximately round, or spherical. However, when looking at a star with the naked eye, it may not appear perfectly round due to factors such as tearing in the eyes and vapor in the air. When looking at them through a telescope, the round shape can be seen. This slight bulging in the middle of the stars is due to their rotation. Some telescopes may show an optical cross aberration, but this is due to the telescope's optics, not the star itself.

Is all the planet and star are round? If so, why when we look at star the shape is not round. If anybody ever think the star are actually shine through
in between 4 rounds.

They are all (approximately) spheres1, i.e. round. If you look at them through a telescope2 you can see it. Naked eye appearance is affected by tearing in your eyes, vapor in the air and so on and so on.

1 They are slightly bulged out on the middle due to rotation.
2 Some telescopes show an optical cross abberation, this is understood and due to th optics of the telescope, not the star.

Related to Round or Not: The Shape of Planets and Stars Explained

1. Are all planets and stars round?

Yes, the vast majority of planets and stars in our universe are round. This is due to the immense gravitational pull of these celestial bodies, which causes them to collapse into a roughly spherical shape.

2. Why are planets and stars round?

As mentioned before, the round shape of planets and stars is a result of their strong gravitational pull. This pull causes the materials making up these bodies to be evenly distributed, resulting in a spherical shape.

3. Can planets and stars be any other shape?

In theory, yes, planets and stars can be any shape. However, due to the forces of gravity and the laws of physics, round is the most common and stable shape for these bodies.

4. Are there any exceptions to the round shape of planets and stars?

There are a few exceptions to the round shape of planets and stars. For example, some small celestial bodies, such as asteroids, may have irregular and non-spherical shapes due to their smaller size and weaker gravitational pull.

5. Is Earth the only round planet?

No, Earth is not the only round planet. In fact, all of the planets in our solar system, as well as many other planets found in the universe, are round. However, there may be some planets that have different shapes due to unique circumstances in their formation.
