A sun-moon conjunction is a new moon.
My Question : Within how many degrees from the sun does the moon come, before it is considered a new moon?
i.e, What is the orb, during which a sun-moon conjunction is called a New Moon?

I guess its called a new moon when the moon is approaching the sun and maybe the orb is around 5 degr?
But when the moon starts going away from the sun, its not a new moon anymore?
Eg. Sun at 8 deg Aries, Moon at 12 deg Aries. This is NOT a new moon right?

It is not defined astronomically, unless we use the EXACT moment Sun and Moon are in opposition.

However, it is commonly referred to as New Moon, if the orb is 6 degrees applying and separating (one night).

Yes, but the same thing applies.

(New moon is conjunction, Full Moon is opposition, you`re of course right)
