GALAXY SONG

Just remember that you're standing on a planet that's evolving,
Revolving [rotating] at nine hundred miles an hour [~1,000 mph at Earth's Equator, slower toward the poles].
It's orbiting at nineteen miles a second [~18 mps, ~65,000 mph], so it's reckoned, [Orbit is a synonym for revolve.]
A sun that is the source of all our power.
The Sun and you and me and all the stars that we can see,
Are moving at a million [12,960,000] miles a day,
In an outer spiral arm, at forty thousand [540,000] miles an hour [150 mps],
Of the Galaxy we call the Milky Way.

Our Galaxy itself contains 100 billion stars
It's 100,000 light years side to side,
It bulges in the middle, 16,000 [15,000] light years thick
But out by us it's just 3,000 light years wide.
We're 30,000 light years from galactic central point.
We go 'round every 200 [250] million years
And our Galaxy is only one of millions and billions
In this amazing and expanding Universe.

(instrumental break)

Our Universe itself keeps on expanding and expanding
In all the directions it can whiz
As fast as it can go, the speed of light you know,
12 million miles a minute [~11.2 mi./min., 186,000 mps], and that's the fastest speed there is.
So remember when you're feeling very small and insecure
How amazingly unlikely is your birth
And pray that there's intelligent life somewhere up in space
'Cause I'm afraid that we've been cheated here on Earth.
