About The Sun
Sun is the center of our local solar system and the most influential
object in that solar system. The Sun, a ball of hot gases, influences
how this solar system works and how each planet in this solar
system functions. Below are several facts about the Sun and its
influence on our solar system.
Dependence on the Sun
We are able to survive on Earth due, in a large part, to the Sun.
According to NASA, the Sun gives us heat, light, food, and the
air we breathe. The Sun powers the atmosphere to give us wind
and rain. The coal and oil that generate electricity for light
and power come from plants and animals that lived hundreds of
millions of years ago and depended on the Sun for life.
The Sun provides heat for the land, oceans, and air. The Sun also
evaporates water from lakes and oceans, which eventually causes
rain and snow. This provides the moisture we need for drinking
water and for plants to grow.
The Sun play’s a vital role in how plants turn carbon dioxide
into oxygen. The Sun’s rays cause green plants to turn carbon
dioxide and water into carbohydrates. While doing this plants release
oxygen into the air. Humans and animals rely on this oxygen to
breathe. The process of production of carbohydrates by green plants
is called photosynthesis. The plants use the carbohydrates as nourishment
to grow and we use plants for our nourishment.
Statistics About the Sun
The Sun is made up of various gases. By weight, the Sun is 70%
hydrogen, 28% helium, 1.5% carbon, nitrogen, and oxygen, and
0.5% all other elements. The Sun’s core temperature is
22.5 million degrees Fahrenheit (14 million degrees Celsius)
and the surface temperature is 9,932 degrees Fahrenheit (5,500
degrees Celsius). The temperature of sunspots is about 7,232
degrees Fahrenheit (4,000 degrees Celsius).
A solar cycle is about eight to eleven years and the distance
to the nearest star is about 4.3 light years away. The Sun is 4.5
billion years old and the diameter of the sun is about 870,000
miles (1.4 million km). Its rotation period at the equator is 25
Earth days while its rotation period at the poles is 35 Earth days.
Facts about the Sun in Relation to the Earth
The average distance from the Sun to the Earth is 93 million miles
and it takes light eight and a half minutes to travel from the
Sun to the Earth. The diameter of the Sun is 109 times larger
than the Earth’s and its volume is big enough to hold over
a million Earths. The mass of the Sun is 330,000 times that of
