"Our planet is Earth."

Translation: Nasza planeta to Ziemia.

[IE99]

Why use naszą planetą here?

[hwodzak]

Can't it be "ziemia jest naszą planetą"?

[Jellei]

That's "Earth is our planet", so you start with the knowledge about "the Earth".

Here we have a sentence that says what is the planet we live on called.

All the time I'm doing this one it is always "Ziemia jest naszą planetą". And it means in Polish that the planet we live on is the Earth. And that is the way I understand this English sentence. And IMHO it should be accepted.

As above:

"That's "Earth is our planet", so you start with the knowledge about "the Earth".

Here we have a sentence that says what is the planet we live on called."

On Duolingo we're keeping the structure of translations as close as possible.
