What causes a blue moon?

The effect can be caused by smoke or dust particles in the atmosphere, as has happened after forest fires in Sweden and Canada in 1950 and 1951, and after the eruption of Krakatoa in 1883, which caused the moon to appear blue for nearly two years. Other less potent volcanoes have also turned the moon blue.

Why does a blue moon happen?

Blue-colored moons are rare – aren't necessarily full – and happen when Earth's atmosphere contains dust or smoke particles of a certain size.

What is the rarest thing to see in the sky?

Did Earth ever have 2 moons?

The simple answer is that Earth has only one moon, which we call “the moon”. It is the largest and brightest object in the night sky, and the only solar system body besides Earth that humans have visited in our space exploration efforts. The more complex answer is that the number of moons has varied over time.

What is the rarest color of the moon?
