The Sun is the star at the center of the Solar System. It is almost perfectly spherical and consists of hot plasma interwoven with magnetic fields. It has a diameter of about 1,392,000 km, about 109 times that of Earth, and its mass (about 2×1030 kilograms, 330,000 times that of Earth) accounts for about 99.86% of the total mass of the Solar System. Chemically, about three quarters of the Sun's mass consists of hydrogen, while the rest is mostly helium. The remainder (1.69%, which nonetheless equals 5,628 times the mass of Earth) consists of heavier elements, including oxygen, carbon, neon and iron, among others.
The Sun's stellar classification, based on spectral class, is G2V, and is informally designated as a yellow dwarf, because its visible radiation is most intense in the yellow-green portion of the spectrum and although its color is white, from the surface of the Earth it may appear yellow because of atmospheric scattering of blue light. In the spectral class label, G2 indicates its surface temperature of approximately 5778 K (5505 °C), and V indicates that the Sun, like most stars, is a main-sequence star, and thus generates its energy by nuclear fusion of hydrogen nuclei into helium. In its core, the Sun fuses 620 million metric tons of hydrogen each second. Once regarded by astronomers as a small and relatively insignificant star, the Sun is now thought to be brighter than about 85% of the stars in the Milky Way galaxy, most of which are red dwarfs. The absolute magnitude of the Sun is +4.83; however, as the star closest to Earth, the Sun is the brightest object in the sky with an apparent magnitude of −26.74. The Sun's hot corona continuously expands in space creating the solar wind, a stream of charged particles that extends to the heliopause at roughly 100 astronomical units. The bubble in the interstellar medium formed by the solar wind, the heliosphere, is the largest continuous structure in the Solar System.
Here comes the sun
And the day has just begun
So come on and have som fun
On and on, to the break of done, break of done
On and on, to the break of, break of done, uh (x3)
It's a brand new day, R'n'G swinging your way
With the summer jam that makes you go "haaay"
Love and happiness, that's what we're dealing
I'm a bilion, now show me what you're feeling
The weather is nice, step outside now call the fight
To be your guide, enjoy the ride
You might be chillin on the beach
On the corner of the freak
My sound be pumpin in your boom-box of energy
Checkin out the honeyz, laying by the pool
All the from the old and new school acting cool
At the court shooting hoops, with the troops, oops
There it is, I got you jumping on my loot
Got my Timbalands on, I let my pants sacks
Shakes of my head, now tell me who's the next
Hands in the air, get your groove on,
Move to the break of done, uh
Chorus:
Here comes the sun
And the day has just begun
So come on and have som fun
If you really think that you're the one
Just come on and have som fun
Here comes the
Here comes the
Here comes the sun
I hit you with the summer rhyme
Time after time
But your body in posistion
Let the rhythm free your mind
The sun is coming thru
You'll be pickin up your crew
The grind and funk is in the air for you
On your way to the picknick
You're feeling teriffic
To the break of done,
You'll be hanging with the click
It's summertime, that's what it is
Pump your fits, the party is on
Now bump your head to this
R'n'G flow on your radio, here we go
Let your boody shake
To the rhythm of a tambo
A two man band, rockin the land
Make some noice, grab a 6-pack in your hand
And just step off, step off to the summer body, huh
Forget about your money
You wanna be my honey
Let's get together and have some fun
To the break of done
Here comes the sun
Chorus
Bridge:
It's a sunny day, tell me can you feel
Everybody together, we gotta keep it real
(Here comes the, here comes the, here comes the sun)
We gotta keep it real
Chorus
On and on, to the break of done, break of done
