Moon Phase and Visibility in Brasilia, Brazil

The moon’s appearance and visibility in Brasilia, Brazil, vary significantly throughout the month. The moon’s phase, which determines the illuminated portion we see, goes through a cycle of new moon, waxing crescent, first quarter, waxing gibbous, full moon, waning gibbous, third quarter, and waning crescent.

The new moon occurs when the moon is positioned between the Earth and the sun, rendering it invisible to observers on Earth. As the moon orbits the Earth, it gradually waxes, becoming increasingly illuminated until it reaches its first quarter phase, where half of the moon’s face is visible. The moon continues to wax, culminating in the full moon phase, where the entire face of the moon is illuminated. After reaching its peak, the moon begins to wane, with its illuminated portion progressively diminishing until it reaches the third quarter phase, where half of the moon’s face is visible again. The waning phase continues until the moon returns to the new moon phase, completing its cycle.

The moon’s visibility in Brasilia is influenced by the time of day and the time of year. During the new moon phase, the moon is not visible as it is too close to the sun. As the moon waxes, it becomes more visible in the evening sky. By the full moon phase, the moon is visible throughout the night. During the waning phase, the moon is more visible in the morning sky. The moon’s position in the night sky also changes depending on the time of year due to the Earth’s tilt on its axis.

Humidity in Brasilia, Brazil – Variation throughout the Year
