In the asteroid impact simulation, the Japanese naration refers to the Earth as "hoshi", which is actually correct since "hoshi" has the same meaning as "astre" in French. The problem is that I don't think there is an equivalent term in English, despite being a somewhat vital astronomy term.
People tend to translate "astre" and "hoshi" by "star" in English, which is not exactly correct. "Astre" and "hoshi" are generic tems that can mean star, planet, meteor, asteroid, comet, satellite, or pretty much any single object in the sky. That term is also very often used to mean the Earth itself.
So is there an equivalent term to the French "astre" or Japanese "hoshi" in English? Other than "definition" sounding terms that nobody really use in common situations like "stellar object" or things like that?
