Viewing Earth from the Moon
Looking at the Earth from the Moon, it's a relatively small, blue sphere. Because the Moon doesn't rotate, you have to be on the right side of the Moon to see the Earth at all. If you're on the side of the Moon that can see the Earth, it would be in your sky all day and night. The Earth stay in the sky but would wax and wane, just as the Moon does as seen from our world. So considering how memorizing people can find a full Moon, how would a bright full Earth look on the Moon? From the Moon, the Earth would be about 3.7 times bigger in diameter. The Earth has a diameter of 7926 miles, compared to the Moon's only 2159 mile diameter. The hardest thing to simulate is the difference in brightness. People lucky enough to walk on the Moon in our times have noticed a very striking phenomenon, a full Earth from the Moon appears much larger and is much brighter. It's true that a full Moon can appear very bright due to its surface (composed of rather reflective yet dull gray dust), however, the Earth has white clouds, oceans and polar ice caps which can reflect much more light that the Moon does. Remember, the Earth and the Moon do not give off they're own light, rather it's reflecting the sun's light.
Earth and Moon phase
Earth and Moon phases are direct opposites of each other, basically they appear as the other one does only in reverse. When we would see a nearly full Moon, people on the Moon would see a slim crescent Earth. The next time you see a crescent Moon from Earth, imaging people on the Moon seeing a nearly full Earth hanging in the lunar sky. Just like the Moon, Earth also goes through a cycle of phases over the period of a month, you will (from the Moon) witness a Full Earth, Gibbous Earth, Quarter Earth, Crescent Earth, and New Earth. The Moon always keeps one side (called the Near Side) facing Earth as it orbits around us, hence, depending on your location, Earth would always appear in the exact same place in the night sky. If you were standing in the middle of the near side of the Moon, Earth would appear directly overhead. If you are on the far side of the Moon, you would never see the Earth because that side of the Moon will never rotate to turn twoards Earth. If you were to walk to a place between the near and far sides of the Moon, the Earth would be "frozen" or about in a state of being "half-risen" on the Moon's horizon.
Measuring Albedo
The property of Earth's brightness when viewing from the Moon is a matter of Albedo or a measure of reflectivity of celestial bodies. Earth has an average Albedo of 0.367 or 36.7% of sunlight reflecting from it. The Moon has 0.12 or 12% Albedo. Earth is 3 times brighter than the Moon. Astronauts that walking on the Moon say that "Earth-shine" is so bright that it's almost like daytime. When the angles of the Earth and the Moon are right, the Earth's oceans act like a mirror, much like those garden globes that act like small ball shaped mirrors in your garden. From the Moon, you can see a mirror image of the sun reflecting off one of Earth's oceans. This makes Earth-shine view much more bright, colorful and interesting rather than watching Moonshine from Earth. We can certainly see how much Earth-gazing will be popular among the first Moon colonies.
