Names follow a set pattern. There are words/sound patterns that are accepted and commonly used as names. And then there are those which are not.
If someone had a name that meant "heavenly body" somewhere, or at some point in it`s history but which was currently a name or accepted as one (such as Autumn, etc) that is fine.

Tentai does NOT follow that pattern. It`s not a name, and would never mean anything other that "Heavenly-Body" or "Astronomical" to anyone who heard it said.
It was asked whether Tentai is a Japanese first name. It is not, and would elicit the same reaction as a 100% American being named "Heavenly-Body" (Exactly that, not something that means that in another country or that had that meaning in the past, etc) in America.
I wouldn`t actually LAUGH at them, but I would judge whether they had been given the name by their parents (and feel a little bad for them) or whether they had changed their own name to that (and find it hard to take them seriously in most cases.)

Why does names have to follow a set pattern?
