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?

Great stuff! I can understand how to add a slicer to the pivot table, but how do you implement the departmental selector on the 'Filter' formula scheme?
Just saw this on your Youtube channel, and it’s areat idea...!
An easy way to overcome the "ugliness" of pivot tables and get it to look nice (in the format of the Output sheet), would be to simply build a sheet with the nice map at the top, a pivot underneath it and a slicer next to formatted map and then reference each of the 9 cells in the formatted map to the “related” cell in the Pivot.
Keep up the good work!

Thanks Claus. That is a great idea 🙂
Hi Chandoo,
This is great! Curious how to make additional columns operate the same as the Department column (ex. have a "manager column") that would allow you to sort a 9 box by manager, area, or team in addition to department?
Feel free to email me if needed! mfry01@minnetronixmedical.com
Happy New Year

I am curious about the smae thing. I would like to populate the 9 box with other views as well by adding additional columns. IE., I would like to add location, region, etc. Thank you.
This is great, thank you!
How can i see the whole data set of all the teams in the output table. Need a formula that will pick up all the employees
Hello,
Love the template. Thank you. Question - the drop down to pick a department on the Output tab does not seem to work on the downloadable template. Am I doing something incorrectly?
Thank you!
Hi Heather... Thank you. I am using Excel 365 to make the calculations. If you are using an older version of Excel, then the drop-down filter won't work.
Hi
I was able to follow your 9 box grid and modified based my needs. However, you tutorial did not show how to you create the filter for the "Pick a department. Can you kindly share how to create that filter that updated the grid. Thank you.
I am working on this project but I am struggling with the data validation for the department. I copy the worksheets data entry and output as the managers want to see different tabs for each managers.
I updated the source reference for each tab but It does not update the grid based on the new source. The list was updated but it does not populate the grid based on the performance and potential listed.
In addition the hyperlink Update Data and View Talent Map no longer works. Can you please help me.
I keep getting this error message in the pivot table:
This formula is invalid or incomplete: 'The expression is not valid or appears to be incomplete. Please review and correct the expression.
The following syntax error occurred during parsing: Invalid token, Line 1, Offset 14, ‘.
Hi, I used your 9-box excel template with excel 365. First off, thank you so very much. It is incredibly helpful!! My only question is that the boxes aren't big enough for all of the employees (specifically the middle which we call 'Core Employee'). Is there a way to make the boxes larger? Even though it is in excel, I am not able to increase row height (like I normally do in a speadsheet). Any ideas? Thanks again, Jody
Hi Chandoo,
Thanks for the great content. Re. 9 box grid, pls advise how do I increase the size of the box to accommodate more names?
Hi Chandoo,
I figured it out. Excel 365 has the format row height on the ribbon. Thank you
Merci Chandoo pour le modèle proposé,
j'ai une question et un souhait est il possible de développer davantage ce modèle en insérant la photo de chaque employé.
Hi Chandoo!
Great tutorial and tool, thank you! Your tutorial didn't include how to create additional filters on the "Output" tab. Could you please share how you did it?
Can this be done exactly in google sheets?
Hi Chandoo,
Thanks for the video it was really helpful. Is there any way to multi select the dropdown to display multiple or all departments rather than just one at once?
Hello Prish
I have Microsoft 365 and I am struggling to make the boxes larger/unable to increase row height; any idea how you made this work? Specifically in the Output tab where the map is?
Many thanks
Hello Jody, I have Microsoft 365 and I am struggling to make the boxes larger/unable to increase row height; any idea how you made this work? Specifically in the Output tab where the map is? Many thanks
Is there a way to change the 9 box wording descriptions, i.e. Work Horses, to our own internal langauge?
You can edit the file. The descriptions are textboxes.
Hi Chandoo, this is awesome and has worked perfectly. Due to a big organisation the 9 box grid on the output file is too small. I tried adjusting using the row/width ribbon under the format ribbon however it doesn't seem to work. Is there an easier way to adjust this?
Thanks!
When I drag the formula, it doesn't work, and the order I use with the data changes. In the beginning, the order is it is " candidates," " potential," and " performance," but when it goes to another column, it is " Potential," Performance," and "Candidates."Can you help me? Thank you very much, sending love from vietnam
Hi- I am working on the 9 grid project and I am trying to expand the box since I have over 100 names on a few of the columns. How do I do that?
Hi, Thank you this is great stuff and really useful.
As well as department as demonstrated on your clip, how can I display all candidates on the grid at once?
Many thanks in advance
