do you know about the stars?
What are they made of?

A star is a massive, bright astronomical spherical body of plasma held together by gravity. The star derives its brilliance from the nuclear energy generated in it, where hydrogen atoms fuse with each other to form elements heavier than hydrogen, such as helium, lithium and the rest of the light elements even iron formation of stars from gatherings of dust and gas in space called nebulae The star lives for about 10 billion years (10 thousand million years)

How long does a star live?

billions of years

Three facts about stars:

Stars vary in color due to their different surface temperatures

The larger the star's size and surface temperature, the greater its brightness

A star lives billions of years

A star is a massive, luminous sphere of plasma held together by gravity. At the end of its lifetime, a star can also contain a proportion of degenerate matter. The nearest star to Earth is the Sun, which is the source of most of the energy on Earth. Other stars are visible from Earth during the night, when they are not obscured by atmospheric phenomena, appearing as a multitude of fixed luminous points because of their immense distance. Historically, the most prominent stars on the celestial sphere were grouped together into constellations and asterisms, and the brightest stars gained proper names. Extensive catalogues of stars have been assembled by astronomers, which provide standardized star designations.For at least a portion of its life, a star shines due to thermonuclear fusion of hydrogen in its core releasing energy that traverses the star's interior and then radiates into outer space. Almost all naturally occurring elements heavier than helium were created by stars, either via stellar nucleosynthesis during their lifetimes or by supernova nucleosynthesis when stars explode. Astronomers can determine the mass, age, chemical composition and many other properties of a star by observing its spectrum, luminosity and motion through space. The total mass of a star is the principal determinant in its evolution and eventual fate. Other characteristics of a star are determined by its evolutionary history, including diameter, rotation, movement and temperature. A plot of the temperature of many stars against their luminosities, known as a Hertzsprung–Russell diagram (H–R diagram), allows the age and evolutionary state of a star to be determined.

Stars are found in space in groups
توجد النجوم في الفضاء على شكل مجموعات.

.Very wide distances separate us from the stars
يفصل بيننا وبين النجوم مسافات شاسعة للغاية.

.Stars differ from each other in shape, size, color, and degree of luminosity
تختلف النجوم عن بعضها البعض في الشكل والحجم واللون ودرجة اللمعان.

Solar brightness: L⊙ = 3.827 × 1026 watts Solar radius: R⊙ = 6.960 × 108 m Solar mass: M⊙ = 1.9891 × 1030 kg

Astronomical observations have shown that a large proportion of stars have planets revolving around them, just as they are in the solar system.  The closest star to Earth is the Sun, which is the source of energy for the Earth.

These stars have a prevalence of around 10%, with a spectral type K. They have temperatures between 3.700 K to 5.200 K, with luminosities around 0.08 to 0.6 that of the Sun. They have a mass of 0.45 to 0.8 that of our sun and last around 15 to 30 billion years.They emit less UV radiation and remain stable for long periods of time making them very favorable for exoplanets that might reside in their habitable zone. They are about four times as common as G-type stars. Some examples of orange dwarf stars are: Alpha Centauri B, Epsilon Indi.

Stars are flaming and luminous bodies of their own. Hydrogen gas constitutes the largest proportion of star formation. Both helium gas and a small percentage of the elements with a low atomic weight enter the formation of stars. The Sun is the largest star in terms of size, and it is also the closest star to Earth, and its distance from Earth reaches 150 km

Supernova: The so-called supernova, which is a way in which the lives of stars end,

Giant stars: They are huge stars and their luminosity is very intense, and their masses are greater than the sun by a few times as a result.
Sequence stars: These stars are considered regular stars similar to the Sun
.Neutron stars: They are the remnants of the great colonies, and these stars are characterized by their enormous density
