I was pinged for writing "The Earth orbits the sun".
I'm surprised that my translation wasn't added before the course hit Beta, it's that obvious.
To be far though, I've always thought of "Orbit" as the standard way to convey this idea, and later on came to understand "Move around/about" and "Circle" as strange but somewhat understandable alternatives.
- "Terra" is the name of our planet in the Romance languages.
- Terra is also the way they say land in Romance languages.
"Earth" was the closest way to say the second meaning of earth in Old and Middle English, and also meant "A plot of land", and from that "Soil".
Earth is now used as the name of our planet in English, and can also mean "Soil".
I don't know if "Soil" is "tero" in Esperanto, or something else.
