The angular distance refers to the angle and distance between the sun and the moon in the sky. When the angle between the two is between 120 degrees and 170 degrees, and the distance is appropriate, the first requirement is met. a condition.

The second condition is clear weather. To see the sun and moon appear in the sky at the same time, the weather must be clear that day. After the wind picked up last night, the haze in the sky has been blown away, revealing a rare clear sky.

The sun and moon shining together is just a natural phenomenon. For the phenomenon of the sun and the moon to shine at the same time, the sun and the moon need to be above the horizon at the same time.

The legend of the sun and the moon shining together

It is said that there is this beautiful legend. It is said that the sun god has ten sons, and only the youngest son, Rizai, is kind-hearted and kind-hearted. When the Sun God was old and frail, Ciri was by his side to take care of him all day long.

There has always been a knot in the heart of the Sun God, but he could never tell it. At the moment of his death, when his eyes met the sun for a brief moment, he died with a smile. At the same time, Ciri also had vague memories of his past life, subconsciously hiding a true and pure light in his heart.

After the death of the Sun God, the ten sons showed off their light and heat in the sky, and only the thorn sun has always retained the most dazzling light.

Everything on the earth was destroyed by the light, and then Hou Yi shot the sun. Hou Yi mercilessly shot the first nine suns to death. When he drew his crossbow and shot at the thorn sun, he hesitated. Where was the thorn sun shining on the earth? His gaze on the earth is as kind as a mother looking at her son, and as gentle as a child stroking his beloved teddy bear. Hou Yi still gave up.
