extremely 1 gases. The surface temperature is about 11,000 F., hot enough
to turn every 2
to vapor (气体), but relatively cool compared to
the strong heat at the 3
.
Located about
93 million miles 4
the earth, the sun has
a diameter (直径) that is nearly equal to 109 of our ear ths 5 up
like a row of beach balls, and a mass that is about 330 000 times the mass of
the earth.
The sun is
the original source of nearly all our 6
. It is mostly made of hydrogen (氢), 7 it
also contains nearly every other kind of atom (原子 )that exists on the earth. The
sun obtains its energy from a process of fusion (溶解) in which hydrogen atoms are
changed into helium (氦) atoms 8
extreme heat and
pressure. This process creates a great noise, but we cannot hear it because 9 does
not travel through empty space.
Our sun is
not even 10 large or bright compared to 11
stars. Stars vary in
size from smaller than the earth to large enough to hold a good part of our
solar system (太阳系)! The 12
of a star shows its
temperature. A star may be red, yellow, white, or blue.
The nearest
star is 4.3 light years from the earth. A light year is the 13 light
travels in one year, or about 6
million miles. The 14 stars
are billions of light years away. Some are 15
far away that if they
were to blow up today, their light would continue to be seen from the earth 16 a
million years! Our sun is part of a great galaxy (星系) of 30 billion
stars called the Milky Way. 17 ,
there are billions of galaxies within 18
of our telescopes and
countless billions beyond. The bigness of space quite __19 human comprehension. How exciting it is
