Ptolemy
3. The apparent backward motion of the planets is called?.......
Retrograde Motion
4. This crazy backward motion of planets was explained by imagining they followed circles within circles as they orbited the earth. What is the name given to these cycles?
Epicycles

I was thinking about asteroids.
That reminded me of potatoes.
Which reminded me of a song about Bobby.
Me too.

Hello Earth
Kate Bush
Hello earth
Hello earth
With just one hand held up high
I can blot you out
Out of sight
Peek-a-boo,
Peek-a-boo, little earth
With just my heart and my mind
I can be driving
Driving home
And you asleep
On the seat
I get out of my car
Step into the night
And look up at the sky
And there's something bright
Traveling fast
Look at it go
Look at it go
Hello earth

Hello earth
Hello earth
With just one hand held up high
I can blot you out
Out of sight
Peek-a-boo,

With just my heart and my mind
I can be driving
Driving home
And you asleep
On the seat
I get out of my car
Step into the night
And look up at the sky
And there's something bright
Traveling fast
Look at it go
Look at it go
Hello earth
Hello earth
The choral section, performed by the Richard Hickox Singers, is taken from a Georgian folk song called 'Zinzkaro' ('By The Spring'), which Kate heard performed by the Vocal Ensemble Gordela on the soundtrack of Werner Herzog's 1979 film Nosferatu The Vampyre. The lyric translates as:
'I was passing by the spring.
There I met a beautiful woman with a jug on her shoulder.
I spoke a word to her and she left, offended.
I was passing by the spring.'
'I was passing by the spring.

Another one of my songs about space! Samples are from the classic sci-fi movie FORBIDDEN PLANET.
I like this guy.
Small changes in Initial conditions can profoundly effect final conditions.
