[Eli5] How does moon’s phases work?

766 views

I know it’s sun’s light that reflect back on earth, but how sometimes we see it on bright day? And why full moon wouldn’t be eclipse if it’s the phase the moon is right in front of the earth and the sun illuminating right behind? Shouldn’t it also depend of earth rotation, seeing slightly different angle by sunrise or sunset?

Late to the party, but the simple answer is that the moon isn’t behind the earth when you can see it during the day. It’s more off to the side [like this.](https://www.schoolsobservatory.org/sites/default/files/astro/esm_all.gif)
