Facts About The Sun by tayexz(m): 11:01pm On Aug 10, 2016 |
QUICK SUN FACTS
At its centre the Sun reaches temperatures of 15
million °C.
The Sun is all the colours mixed together, this
appears white to our eyes.
The Sun is mostly composed of hydrogen (70%) and
Helium (28%).
The Sun is a main-sequence G2V star (or Yellow
Dwarf).
The Sun is 4.6 billion years old.
The Sun is 109 times wider than the Earth and
330,000 times as massive.
DETAILED SUN FACTS
One million Earths could fit inside the Sun. If a
hollow Sun was filled up with spherical Earths then
around 960,000 would fit inside. On the other hand if
these Earths were squished inside with no wasted
space then around 1,300,000 would fit inside. The
Sun’s surface area is 11,990 times that of the
Earth’s.
The Sun contains 99.86% of the mass in the Solar
System. The mass of the Sun is approximately
330,000 times greater than that of Earth. It is
almost three quarters Hydrogen, whilst most of the
remaining mass is Helium.
The Sun is an almost perfect sphere. There is only
a 10 kilometre difference in its polar diameter
compared to its equatorial diameter. Considering the
vast expanse of the Sun, this means it is the
closest thing to a perfect sphere that has been
observed in nature.
The temperature inside the Sun can reach 15 million
degrees Celsius. At the Sun’s core, energy is
generated by nuclear fusion, as Hydrogen converts
to Helium. Because hot objects generally expand,
the Sun would explode like a giant bomb if it weren’t
for its enormous gravitational force. The
temperature on the surface of the Sun is closer
to 5,600 degrees Celsius.
Eventually, the Sun will consume the Earth. When all
the Hydrogen has been burned, the Sun will
continue for about 130 million more years, burning
Helium, during which time it will expand to the point
that it will engulf Mercury and Venus and the Earth.
At this stage it will have become a red giant
The Sun will one day be about the size of
Earth. After its red giant phase, the Sun will
collapse, retaining its enormous mass, but
containing the approximate volume of our planet.
When this happens, it will be called a white dwarf.
Light from the Sun takes eight minutes to reach
Earth. With a mean average distance of 150 million
kilometres from Earth and with light travelling at
300,000 kilometres per second, dividing one by the
other gives us an approximate time of 500 seconds,
or eight minutes and 20 seconds. Although this
energy reaches Earth in a few minutes, it will
already have taken millions of years to travel from
the Sun’s core to its surface.
The Sun travels at 220 kilometres per second. The
Sun is 24,000-26,000 light years from the galactic
centre and it takes the Sun 225-250 million years to
complete an orbit of the centre of the Milky Way.
The distance from the Sun to Earth changes
throughout the year. Because the Earth travels on
an elliptical orbit around the Sun, the distance
between the two bodies varies from 147 to 152
million kilometres. The distance between the Earth
and the Sun is called an Astronomical Unit (AU).
The Sun is middle-aged. At around 4.5 billion years
old, the Sun has already burned off about half of its
store of Hydrogen. It has enough left to continue to
burn Hydrogen for approximately another 5 billion
years. The Sun is currently a type of star known as
a Yellow Dwarf
The Sun has a very strong magnetic field. Solar
flares occur when magnetic energy is released by
the Sun during magnetic storms, which we see as
sunspots. In sunspots, the magnetic lines are
twisted and they spin, much like a tornado would on
Earth.
The Sun generates solar wind. This is a stream of
charged particles, which travels through the Solar
System at approximately 450 kilometres per
second. Solar wind occurs where the magnetic field
of the Sun extends into space instead of following
its surface. 1 Like 1 Share |
