Recently I saw an interesting Earth Venus cosmic dance video on Facebook. See the original video below or here.
Although this is not entirely accurate from physics & astronomy perspectives, the dance is a stunning example of patterns that are generated by simple things.
I wanted to recreate this cosmic dance in Excel. How else am I to get my spreadsheet fix on a Saturday?
Here is a quick demo of the final outcome. Read on to learn more about the Earth Venus cosmic dance.
The details & assumptions
To create this cosmic dance, we need a few details
- Distance from Sun to Venus & Earth – 67.2 and 93 million KM respectively
- Number of days it takes to rotate around the sun – 224.7 and 365.25 respectively
We will also assume these incorrect things to keep our model simple
- Orbits of Earth & Venus are circular with Sun at center: In reality, they are elliptical, but as these are just stretched circles, we can assume circular orbits to keep the math simple.
- Sun is static: In reality, Sun (and entire solar system) is also moving. This means, this cosmic dance may never occur.
We also need one critical detail to graph this cosmic dance:
- The angular interval for plotting the lines. In the above examples, I have used 10° (ie there will be 36 lines around the circle). This is denoted by named range m in the model. You can adjust this in the output worksheet using a form control. Different values of m yield different patterns (although most of them will be pentagonal).
The math:
Generating planetary co-ordinates:
In a table, we will generate the positions (X & Y co-ordinates) of both Venus & Earth for 3000 points in time, each incremented by m degrees, starting at 0°.
To generate the X & Y values, we will use the x=r.cos? and y=r.sin? equations (where r is the distance from Sun and ? is the angle).
Drawing the lines:
This is the tricky part. At each step in the animation our line should from one tooth of the saw tooth pattern. See this demo to understand.
For more about this technique read – interactive network chart to map relationships between people.
So during each step of the animation, we add more co-ordinates to the chart (scatter plot) to generate this saw tooth pattern. Over time, this will yield the beautiful pentagonal cosmic dance.
We can generate these successive Venus & Earth co-ordinates from the calculations performed earlier by using MOD & INDEX formulas.
Once such saw tooth line data is generated, we will designate a cell to hold current animation position. Let’s call this pos.
We will then create two named formulas – dance.x and dance.y. These will contain the data necessary for our scatter plot. We will use OFFSET formula to generate these dynamic named formulas.
The chart
Now that all the necessary calculations are done, create a scatter plot with the dance co-ordinates. Set up X & Y axis minimum and maximum values accordingly (-160 to 160 should do). This ensures that the chart remains same no matter what step of animation we are on.
Also, add 3 more series to the chart
- One for a dot to represent Venus at current position
- One for a dot to represent Earth at current position
- One for a line connecting Venus to Earth
The animation
Next, let’s add a small macro to animate the chart. This macro will increment pos from 1 to a large number. After each iteration, we will call DoEvents so Excel can re-draw the chart. That is all.

Did you enjoy the dance?
I really liked the original video on FB and that is why I recreated this in Excel. This is a great exercise to show the power of simple things generating extraordinary patterns.
What about you? Do you like this Earth Venus dance?

Nice roundup! Do you know of any one-page spreadsheets which will be updated by an administrator after each game? Would be nice to be able to print out the latest results whenever I feel like checking them as I probably won't be following closely every day.
I actually haven't tried any of the above ones yet, but I thought I'd mention this one that I found which makes a nice one-page form you can fill in dynamically. http://exceltemplate.net/sports/world-cup-2010-schedule-and-scoresheet/
I would like to recommend you these one: http://www.anotagol.com/
You can choose your interface language (english, spanish, italian, portuguese, german or french) and your country for the timezone of match. I like it very much.

Does anybody know how to re-create this(?): http://www.marca.com/deporte/futbol/mundial/sudafrica-2010/calendario-english.html
...or do you know where a template can be found? I am DYING to have something like this on my site. When I found it, I had been looking for the longest time for a circular calendar. I found a couple that weren't adequate. Then I stumbled upon this one and my eyes nearly popped out of my head. If anyone can lead me in the right direction, I would be eternally grateful!
Thanks in advance!

@Robert...
Doing something like that is a lot of work. You can probably get it done with some hired help from a flash developer.
@Robert, the World Cup flash in the Spanish Marca newspaper is impresive, but not much as my own animated spreadsheet with the Goals of 2010 World Cup South Africa in Excel that I just published into my blog:
http://pedrowave.blogspot.com/2010/06/goals-of-2010-world-cup-south-africa-in.html
Download from here:

And start to enter the goals of the rest of matches.
Has anyone seen, or made, a Spreadsheet where you can record the scorers and see a 'top scorers' chart. Would be a nice enhancement
@Neil... checkout this one http://www.inflexionary.com/sports/world-cup-2010-excel
it uses macros to fetch scores from web (and provides very comprehensive analysis too)
@All.. Thanks for the comments. I have updated the post with few more links now.

Hey, you missed ours! It has everything you need and more, but not a whole pile of silly extras (National Anthems, etc). I'll be making another one for the 2014 world cup. We had over 4000 hits on it!

I also made a Worldcup-tracker, with MS Access, which can also generate reports in Excel
e.g. a match-schedule with locations on y-axis and dates on x-axis, see:
