Hi

I've found a translation bug in information about creating moon.
English:

A moon was formed around the planet with a diameter of 8.660 km

Polish:

Księżyc o powierzchni 8.660 km został uformowany.

Should be:

Księżyc o średnicy 8.660 km został uformowany.

I reported this over year ago and still you didn't change it. Why?
