Many other stars are visible to the naked eye at night [1] the sun, the orbit of earth, jupiter, and neptune, compared to four stars (pistol star, rho cassiopeiae, betelgeuse, and vy canis majoris) Their immense distances from earth make them appear as fixed points of light.

Of the tens of billions of trillions of stars in the observable universe, only a very small percentage are visible to the naked eye.
How does a star work
How do they form, live, and eventually die Learn more about these distant objects and their major importance in the universe. The meaning of star is a natural luminous body visible in the sky especially at night How to use star in a sentence.
Life cycle of a star what is a star A star is a giant sphere of extremely hot, luminous gas (mostly hydrogen and helium) held together by gravity Stars are essentially the building blocks of galaxies and are the source of all the heavier elements. In a very broad sense, a star is simply one of those twinkling points of light you can see in the night sky
But that’s not terribly satisfying in either lexicological or physical terms.
These large, swelling stars are known as red giants But there are different ways a star’s life can end, and its fate depends on how massive the star is. The simplest way to describe a star is that it is a great ball of fire, but it is more complicated than that A star is a giant ball of hydrogen turning into helium through nuclear fusion.
The pleiades, an open cluster of stars in the constellation of taurus A star is a massive, luminous ball of plasma that is held together by its own gravity The nearest star to earth is the sun, which is the source of most of the energy on earth Other stars are visible in the night sky, when they are not outshone by the sun.
Somewhat related to star clusters are stellar associations, which consist of loose groups of physically similar stars that have insufficient mass as a group to remain together as an organization
This is a list of significant stars ordered alphabetically by the constellations in which they appear, followed by a list of significant star types. Below are lists of the largest stars currently known, ordered by radius and separated into categories by galaxy The unit of measurement used is the radius of the sun (approximately 695,700 km
