Sun, the solar system's only star
Introduction
Stars are born. They take shape. They go through a turbulent adolescence, and then they live out their lives in a predictable pattern. Some have companions to provide for.

A Sun-synchronous orbit is an interesting orbit. Since the Earth is not an exact sphere (it has a slight bulge at the equator) satellite orbits can be effected by the extra gravitational pull.
The sun's atmosphere consists of the chromosphere, corona, and photosphere. The photosphere is the bright visible surface of the sun, with a surface temperature of 5,800 K.
The Sun
Overview
"The sun is only a star / around that star we spin" goes the words of a song "Child of the Universe." The sun is only a star, and an average one at that. It is unimportant in the grand scheme of the universe.

The Sun is the Earth's dominant source light (and thus heat) and the star about which all of the planets of the solar system orbit. The Sun has mass 1.
The sun is a huge, spinning ball of hot gas that glows in the sky. Our sun is a medium sized star. It looks larger and brighter than the other stars because it the nearest star to Earth. It is about 150 million kilometres away.

THE SUN
The Sun is the mother star around which the Earth revolves once a year. It is the source of heat, light, and life itself on the Earth.
The Sun's Surface
The deepest layer of the Sun you can see is the photosphere. The word ``photosphere'' means ``light sphere''. It is called the ``surface'' of the Sun because at the top of it, the photons are finally able to escape to space.

Our Sun is a yellow dwarf star. Its official designation is as a G V star. Stars in the this classification have a surface temperatures between 5,300 and 6,000 K and fuse hydrogen into helium to generate their light.
The Sun's Corona
When the moon covers the bright face of the Sun during a total eclipse, the fainter outer layers become visible: the reddish chromosphere, and above it, the long streamers of the corona.

Wow!
Many ancient peoples worshiped the Sun as a god. They thought a solar eclipse meant the god was angry with them. They believed the Sun god's anger could only be calmed with prayer and sacrifice.

THE SUN. Similar in many languages, "Sun," related to Latin's "sol," was represented in ancient Greece as Helios, god of the Sun.

The Sun also has an influence on the tides, but since it is further away, it doesn't pull as strongly. However, when both the Moon and the Sun are pulling along the same axis, the tides are highest.
Set it on a flat surface and rotate the base of the fixture so that the North Pole is farthest away from an imaginary light source (the Sun). This simulates winter in the northern hemisphere; summer in the southern hemisphere.
Thus, in the Copernican model the Sun was at the center, but the planets still executed uniform circular motion about it. As we shall see later, the orbits of the planets are not circles, they are actually ellipses.
