I learned this in science class- it takes 29 1/2 days for the moon to go from new moon to the next new moon.
29.531 days (rounded)
The complete cycle of the moon's 'phases' ... the time to go from any shapeto the next appearance of the same shape ... averages 29.531 days.
When Venus goes behind the Sun (as viewed from Earth), its phase is full. You can't see it, of course. When it transits the Sun (passes between the Sun and the Earth), it's in its dark phase.
The "waning gibbous" phase lasts from 2 days after the full to 6 days after the full.
NO. Venus is hidden behind the Sun when its phase is "full".

Brighter, since Mars is closest to Earth in its orbit and in a full phase as viewed from Earth.

If tonight the phase of the moon is full when it rises what will be the phase 4 days from now is in the waning gibbous stage.

this depends on what you mean. for the moon to return from one phase to the same (for example new to new or full to full) it takes 29.53059 days (29 days, 12 hours, 44 minutes and 3 seconds). this accounts for the rotation of the earth. so for all intents and purposes as viewed from the earth's surface- this is the best answer. if you watch and measure from anywhere on earth, this is the duration of one lunar orbit. the most exact answer for the question as i interpret it is on average 27.21222 days- this is the nodal month, which is the duration the mood takes to travel from one node of its orbit to the same node. this does not take into account the rotation of the earth. this is 'one complete trip' as viewed from anywhere outside the earth and is more accurate for this question as i interpret it.
If you are standing on the full moon you would be facing the earth at night.
As seen from the moon, the Earth is a brighter source of light than the moon is as seen from the Earth. This also depends upon the phase of the Earth, just as the brightness of the moon varies by phase. A full moon and a full Earth are in the brightest phase.
