Introduction Have you wondered what stars were? Did you know stars can die? Did you know the sun is a star? Did you know that stars are huge?
A Star A star is a big sphere of plasma held by its own gravity. The nearest star to earth is the sun. Which is the source of most planet's energy? Some star are visible at night on earth looking like a multitude fixed luminous due to their distance. The brightest stars had their own name. Other stars assembled astronomer provide star designation.
Fun fact There are about 400 billion stars in the galaxy
The Sun The Sun is the main part of our solar system. It provides the energy needed for life to persist on Earth, as well as gravitationally bind the planets in their orbits. This star makes almost 99.86% of the total mass in the solar system.
Upon the surface of the Sun there are many recognized features, many of them were discovered by Galileo. Among these are Sun spots, solar prominences and solar flares. The frequency at which these facts appear they are an indication of where the Sun is in its solar cycle. Solar flares have also been the subject of many theories of how the Earth may finally meet it end.
Parts of the Sun
The parts of the sun is the core, the radiative zone and the convective zone. The core make 25% of the sun.The radiative zone make up 45% .And the convective zone make up 30% of the sun.
Death of stars Most stars take millions of years to die. When a star like the sun runs out of hydrogen fuel, it expands and turns into a red giant. It may be millions of kilometers across big enough to sallow Mercury and Venus.
After puffing out is layers the star collapses to form a very dense white dwarf. A white dwarf weighs up to 100 tones. Over billions of year a white dwarf cools and becomes invisible.

An American space probe to Jupiter launched in 1989. It reached the vicinity of Jupiter in 1995 and released a probe which descended into Jupiter's atmosphere.
Indication Gravity
Physics the force that attracts a body toward the center of the earth, or toward any other physical body having mass. For most purposes Newton's laws of gravity apply, with minor modifications to take the general theory of relativity into account.
White dwarf A small very dense star that is typically the size of a planet. A white dwarf is formed when a lowmass star has exhausted all its central nuclear fuel and lost its outer layers as a planetary nebula.
