The moon orbits the earth once every lunar month (28 days). When it is between the earth and the sun (though normally it is in a slightly different plane so is not directly between them; when it is you get a solar eclipse) the moon cannot reflect the sun's light back to earth, so we see a "new" moon, that is, just a tiny crescent or nothing at all.

When the moon is at the other side of its orbit, that is, on the opposite side of earth from the sun, we see the whole of the moon's disc reflecting the sun's light back to earth, a full moon (unless it is exactly in the same plane as earth and sun, in which case there is a lunar eclipse caused by earth's shadow).

Waxing and waning occur between these two extremes.

The sun is a giant ball of plasma and within it, at the center, atoms ricochet off eachother with such force that they sometimes combine to form a heavier atom.

When this occours, some of their mass is shed and converted into energy across the electromagnetic spectrum, including visable light. This energy radiates out and reflects off objects and is collected in our retinas and forms an image.

The moon is nothing more than a lump of earth cast off in an enormous impact with an object nearly as large as our own planet. The light of the moon is only the sun's light reflecting off it.

As the moon circles our planet, we only see part of it lit. That part is the portion that faces the sun, while the darkened portion is facing away. And so, as it circles, we watch the area that is facing the sun grow to full, then shrink again into nothing. And 28 days later, it will have grown and shrunk again.

The 'Tenth Planet' may be refering to a few things. Astronomers were, for a time, unable to explain the gravitational pull on planets in our system. So the orbits didn't make sense, yet that's the way they were. Many people assumed there must be a large 'Planet X' that would explain this. Even after Pluto was dicovered, it wasn't large enough to explain the gravitational inconsistancy.

The inconsistancy has been resolved otherwise. There never was a Planet X. Pluto is no longer a planet, so there are Eight planets now.

There is also an object, classified like Pluto as a dwarf planet, that's orbit takes it through the Oort Cloud.

The waxing and waning of the moon is caused by our view of the Moon. The sun always illuminate half the moon (apart from eclipses). However, when the Moon is new (invisible) the Sun is illuminating the side opposite the Earth and we cannot see the illumination. When the moon is full, the Sun is illuminating the side we see. With a half moon, we see half of the illuminated side and half the non-illuminated side.

The Moon is a satellite of the Earth. The Earth is a satellite of the sun. Satellite means that a body proceeds in an orbit around another body.

There is no 10th planet. In fact Pluto, which used to be the ninth planet, has just been downgraded to something else. There are now only eight planets in our solar system.

Waxing and waning of the moon? That's due to the way that the earth, moon, and sun are aligned. Think of a ball that you shine a flashlight on -- only half of the ball will be in light, the other half will be in shadow. If you move around the ball-flashlight setup, you'll see different amounts of the ball being lit up. That's how the moon "changes size" throughout the month.

The moon and sun are as different as an apple and a balloon. Where do I begin? They are made of different things. They are different sizes. They are different distances from the earth. They obviously look different.

The listing of the planets can be found on Wikipedia, here: http://en.wikipedia.org/wiki/Solar_system. There is no tenth planet, as there are only 8 planets in our solar system.

i'm no longer conscious of waxing and waning yet to enhance on a no guy's answer, the human physique is made up of approx. ninety% water subsequently it could be logical to assume that the tidal outcomes the moon has on the oceans would additionally be conscious to us "luggage of water". in spite of the reality that i for my area have faith this is extra probably that this has an result on people on the same time as we are bobbing up interior the womb in preference to as quickly as we are adults. this theory can supply some credit to the perception that the time of 12 months you're born impacts certainly one of those character you get carry of considering that our brains are 70% water. perchance there substitute right into a waning moon while specific aspects of your recommendations have been bobbing up as a foetus? and therefor you sense happier and extra attuned while those situations are repeated p.s i dont examine horoscopes or have any form of activity in astrology
