What would happen if we launched our Swirl rock spiral into space and it managed to connect with the Pinwheel Galaxy?
Here’s what we think it would look like: the Pinwheel Galaxy (aka M101) at the left and our Swirl with its ring of autumn leaves at the right, placed against a backdrop of deep space.
This got me thinking about our place in the universe, so I checked on the relative location and size of these two celestial objects.
- 200 feet from the house
- Diameter of 14 feet
- Contains 139 rocks
The Pinwheel Galaxy
- 21 million light years from the house. The light from the galaxy, traveling at 186,000 miles per second, has taken 21 million years to reach Index, Washington.
- Diameter of 186,000 light years. Yikes!
- Contains 500 billion stars (maybe more).
I tried to calculate how many Swirls could fit within the Pinwheel Galaxy but my math know-how just wasn’t up to the job. So let’s just say that the number is big, unbelievably big.
Even bigger than that.
