    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.
