Two questions, Ray:

1) What kind of name is "P4"?

2) How many other non-planets have a moon or multiple moons?

I only ask because at the moment I'm busy with other work otherwise I'd look it up myself.

P4 is the kind of name they give it until some God or God's friend inspires them.

At least 3 or 4 dwarf planets have moons. Also quite a number of asteroids.

I did not know it had more than one either.

Do any moons have moons?

Somewhere in the deepest recesses of my mind, i vaguely remember seeing something about binary moons around some planet in another galaxy far, far away....

Anybody else??

Oh, ok, how about Dionysus (or Bacchus for those that don't like to type.... ) When this project is done, I'll have to look up those dwarf planets/asteroids. Thanks.

I don't believe that planets can be detected in another galaxy, let alone moons.

No.

From the article:

Now a new study has located yet another extrasolar planet, or exoplanet, within our galaxy.
