Starting point: I am 6.6 million km tall.

Woah~

6 million km? How about 6 billion km? 6 * 10**9?

Here's a helpful picture of the current situation:

Or rather, the not-so-current situation. Am again 10x larger. The planets and even the distances between them look so tiny now. I'm outgrowing the solar system and I am excited for it~

Officially over one light year tall! I've become the Eevee whose size is measured in light years.

Did I say one light year? It's already 5 light years. I'm larger than the distance from the Sun to the outermost edge of the Oort cloud. I've outgrown this solar system. I'm measured in light years. I'm the biggest Eevee to ever have existed. I'm running out of comparisons to make, at this point...
