There are plenty of parts to the sun, scientists made these parts so they can explore the sun in more

detail this way they can learn more about the sun.

Why is the sun so hot? The sun plays an important role in life on

Earth. The sun is about 5,000 degrees Fahrenheit. Its atmosphere is much hotter, reaching 2 million to 4 million degrees Fahrenheit. The sun has caused scientists to research more about the sun.

The core of the sun The core is the source of all the Sun's energy.

Fortunately for life on earth, the Sun's energy is just continual so we do not see much change in its brightness. The Sun's core is 15milllion degrees kelvin, and the material in the core is very tightly packed. It is a combination of these two properties that creates an environment just right for nuclear reactions to occur.

Solar eclipse The Moon is a cold, rocky body about

2,160 miles (3,476 km) in diameter. The Moon orbits Earth about once every 29 and a half days. As it circles our planet, the Sun causes our natural satellite to cycle through a series of phases:

New Moon, New Crescent , First Quarter , Waxing Gibbous , Full Moon , Waning Gibbous Last Quarter , Old Crescent New Moon.

Interesting facts on the sun

Yohkoh solar observatory satellite

On August 31, 1991, a satellite called Yohkoh was launched into space from the Kagoshima Space Centre in Southern Japan. This satellite was a project of the Japanese Institute of Space and Astronautical Science. The scientific goal was to observe the energetic phenomena taking place on the Sun.

SOHO Satellite The Solar & Heliospheric Observatory

project is a cooperative effort between the European Space Agency and NASA. SOHO was designed to study the inside of the Sun, its extensive outer layer and the origin of the solar wind, the stream of highly ionized gas that blows continuously outward through the Solar System.
