Hello, excellent publication, well, we have always known that the earth is round, at least that is what we were taught in the studies carried out in the different institutes where we have passed, but your post is totally logical since at first glance we can see a series of objects in the same line that can also be called planets and the truth is I don't know if the moon or the sun belong to our orbit, greetings from Argentina on behalf of this server @theshot2414 this is my blog, I'll follow you happy day.
