Facts about the Sun
The sun is the center of the solar system which was then confirmed by
Nicolaus Copernicus. The sun is a star, it is a rather ordinary star for not
being the largest nor smallest. It is the source of heat which
helps humans, plants and animals be able to live on earth and
also controls our climate and weather patterns. It is the
closest star
to earth and the most
closely studied. From it we have
learned a lot about how life evolves on earth and physical processes
which helps us figure out the evolution of stars in general
.
Sunspots
The surface of the Sun, which is known as the photosphere, is as hot as 5800
degrees celcius. Sunspots are only 3800 degrees celcius; some
sunspots can be very large and they can reach to 50,000 km
wide in diameter. Sun spots are caused by
unknown interactions with the sun’s
magnetic field.
What would happen if we didn’t have
a sun?
Without the Sun, all life on earth would die. The
Sun is the main source of energy for earth and
all living things on the planet. In addition, if we
didn’t have the sun to orbit, Earth would fly into
space, moving in an infinite line.
Mankind will not remain on Earth forever, but in its quest for
light and space will at first timidly penetrate beyond the confines
of the atmosphere, and later will conquer for itself all the space
near the Sun. - Konstantin E. Tsiolkovsky
