Methone - moon - was created on 2004-06-01.

It has a diameter of approximately 3km.

That would apply to just about any small moon. Larger moons will have a round shape.

I don't know what "methone" means in this instance; I'm assuming you're not trying to swallow one of Saturn's moons, even if it is one of the smaller ones.

Methadone does not show up in the standard opioid test. However, it will very definitely show up on tests designed specifically to test for it.

The proper thing to do if you're taking any prescription medication is to inform the person giving the test; that way they can ignore known false positive results or use a more accurate method.
