What is what does it mean when the moon is orange?

When the moon appears orange, it is typically a result of the moon being lower on the horizon, closer to sunrise or sunset. This phenomenon is known as the "harvest moon effect" or "supermoon effect" and is caused by the scattering of light in Earth's atmosphere.

When the moon is lower in the sky, the light must pass through a thicker layer of atmosphere, which scatters the shorter blue and green wavelengths of light. This leaves the longer red and orange wavelengths to dominate, giving the moon its orange or reddish hue.

Additionally, factors such as atmospheric conditions, pollution, and dust can also contribute to the moon appearing orange. Overall, an orange moon can create a beautiful and striking visual effect in the night sky.
