What does it mean when the moon is orange like tonight?

I just looked outside and the moon is glowing orange does anyone know what it means ?

What does it mean when the moon is orange like tonight?
This effect is caused by the atmosphere of the earth. The reason for the orange color is due to the scattering of light by the atmosphere. When the moon is near the horizon, the moonlight must pass through much more atmosphere than when the moon is directly overhead. By the time the moonlight reaches your eyes, the blue, green, and purple pieces of visible light have been scattered away by air molecules. That's why you only see yellow, orange, or red.


The moon can have an orange color at any time of the year. Sometimes the moon appears orange even when it's directly overhead. This occurs when there's a lot of dust, smoke, or pollution in the atmosphere. The size of those particles will determine the type of color you will see.
Reply:It is due to the diffraction of light through Earth's atmosphere. Blue light scatters easy and only the reddish hues of light remain when it goes partial halfway through Earth's atmosphere. By the same principle, during the day the sky is blue and at twilight the sun is orange/red.





Physics is truly amazing isn't it?
Reply:There is a lunar eclipse going on. These happen once a month.
Reply:I'm not sure if this is true or not, cant even tell you when or where I heard it. But I heard that if the moon is closer it appears orange.
Reply:One of two things. Either it's low in the sky so the color is affected by the atmosphere or there is moisture, dust and polution in the air.
Reply:It's called a Harvest Moon. Not sure what causes it. Beautiful, isn't it?
Reply:Best ignore the previous answer.





1) There is no lunar eclipse today, yesterday or anytime near to now.


2) Lunar eclipses to NOT happen every month.





(But there is one next month. March 3rd. 2244 to 2358 GMT. Visible from Europe %26amp; Africa, even India, but not from not N.America/East Asia. At this time the moon will look more red than orange).





If the moon looked orange it was due to being low, and the light passing through 3+ times more atmosphere than when overhead, esp. if viewed through city smog (or more unlikely, a recent volcanic eruption!).
Reply:the reason for the orange color is due to the scattering of light by the atmosphere. When the moon is near the horizon, the moonlight has to pass through much more atmosphere than when the moon is directly overhead. By the time the moonlight reaches your eyes, most of the shorter waves (green, blue, violet) of visible light have been scattered away by air molecules. You only see the longer wavelength of yellow, orange, or red.





Sometimes the moon appears orange even when it's directly overhead. This occurs when there's a lot of dust, smoke, or pollution in the atmosphere. The size of those particles will determine the type of color you will see. Sometimes the moon will look red, orange...even blue.
