When the moon phase is "waning" then it is not growing. It is better to say that the lit side of the moon is receding from view. Then, when the moon phase is "waxing" the lit side of the moon is coming into view.
I like to remember this by saying that "waxing" means that the moon is "filling up with wax". This is only a way of remembering the naming scheme. Also, if your "energy" is "waning" then you are feeling tired. Thus waning is the decrease of something. In this case, the proportion of the lit vs unlit side of the moon in view is decreasing.
When the phases of the moon are increasing in size, we say that the moon is "waxing". After a full moon and the moon seems to be diminishing, we say that's "waning". (Rhymes with raining)
When the illuminated portion is decreasing from one night to the next, the moon is in its 'waning' phases.
When the moon appears to reduce in size, it is called the "waning" phase. This occurs after the full moon, as the illuminated portion of the moon decreases leading to the new moon phase. The waning phases include the waning gibbous and waning crescent.
The lessening of the illumninated part of the Moon is called "waning" (decreasing). The phases included are waning gibbous (more than 50%), last quarter, waning crescent (less than 50%), and finally the new moon.
The moon is called a waning moon when it is growing smaller in size. This occurs right after a full moon, as the moon transitions from being fully illuminated to gradually becoming less visible.
Wax as an intransitive verb means to grow in size, where as wane means to shrink in size. In terms of moon phases, waxing means getting fuller, going towards a full moon. Waning is the opposite, getting thinner, going towards a new moon.
No, the moon is not growing in size. Its appearance changes due to different phases caused by the position of the sun, Earth, and moon relative to each other.
I'm assuming that you are intending to ask, "What is the decreasing moon phase called?" When the moon is getting smaller, it's referred to as "waning". When the moon is increasing in size, it's referred to as "waxing".
Waxing is an archaic term used to mean something is growing. So, a waxing crescent means that from the observer's position on earth, the crescent moon is increasing in size. The moon's two main phases are waxing and waning. Waning which means it is getting smaller.
Which lunar phases would be visible in the sky at dawn? Full, waning gibbous, Third Quarter, waning crescent, and new. At midnight? Third Quarter, waning gibbous, full, waxing gibbous, and first quarter.
waxing~ Wax as an intransitive verb means to grow in size, where as wane means to shrink in size. In terms of moon phases, waxing means getting fuller, going towards a full moon. Waning- Waning is the opposite, getting thinner, going towards a new moon.
Both of these are English words used in everyday conversation by regular people, but much more in the past than in today's English. Their plain, everyday meaning is directly applicable to the appearance of the moon as it goes through its phases. 'Waxing' . . . growing, becoming larger or fuller as time goes on. 'Waning' . . . shrinking, becoming smaller or skinnier as time goes on.
