The Moon seen on the daytime sky has to do with the relative position of the Sun and the orbit around the Earth
From childhood people are used to seeing “going out” the sun in the day and Moon night, however, there are times when the natural satellite of the Earth can be seen on the blue sky, ie in the mornings or afternoons.
This phenomenon is known as Moon day and is produced by the effect of sunlight reflected on the satellite, and explains Jairo Armijos of Quito Astronomical Observatory.
The moon does not emit its own light, so that its visibility from Earth depends light the only star of the Solar System that is produced by nuclear reactions.
In addition to the reflection of the sunlight, the moon is visible in the day also depends on the relative position Sol- Moon and its orbit around the planet, says Armijo
This is related to visual variations of the satellite, known as moon phases.. new, waxing, full and waning
Antonio Pérez Verde, astronomer Spanish Network for Dissemination of Astronomy (REDA), mentioned as recorded by the RTVE website of Spain that “the full moon only seen at night, the new moon is not seen, the crescent looks at sunset and at night and waning at dawn and morning. “
In this way, turns out to be a very common phenomenon that happens several times a year as the moon grows (the which means that the area receives more light to the advancement of the cycle).
Perez Green adds that “from the perspective of a viewer located on Earth, the Moon is separating the Sun and hiding behind the horizon Each day later than the Sun, “so in these occasions they can see for the day or evening.
