As you know, every once in a while earth casts its shadow on the moon in such a way that it appears as a crescent. But what you may not know is that the moon is drifting away from earth at a snail-like speed of 4 centimeters per year. What does that mean? Well in several thousand years when the moon is several hundred miles further away, earths shadow will be significantly smaller when it is cast upon the surface of the moon. The result of this will be that instead of a crescent, the moon will appear to be giant ring in the sky. I don't know about you, but its weird to think about looking up in a mid-night sky and see a huge moon ring.

Does that mean one day the moon is going to escape from the Earth's gravity and just fly off on a little adventure?! THAT'D BE AWESOME

uhh.. isn't that called an exclipse or somthing?

No, an eclipse is when the earth comes between the moon and the sun. Very different then this.

Actually yes it is an eclipse. A solar eclipse is moon blocking out the sun, casting it's shadow on the earth, whilst a lunar eclipse is when the earth blocks out the sun, casting it's shadow onto the moon

yeah, but earth's shadow would be smaller on the moon if the moon was farther away. the shadow wouldn't be big enough to cover the whole moon anymore, then we will see the moon ring!

i wonder how this would effect the tides

koshka Says:

well seeing as how the moon affects the tides now at its current distance, my hypothesis is that once the moon is farther away, it will have less of an effect on the tides. and I also think that in the past when the moon was closer, the tides were far more dramatic than they are now.

That's a pretty dope hypothesis you have about the tides being more intense, it makes sense too. I wonder if sea creatures evolved to accommodate the extreme waves

Wouldn't it have the opposite effect? If it keeps getting farther and farther away, then it would appear to get smaller and actually be enveloped more by the shadow of the earth.

I don't understand why the Earth's shadow would be smaller if the moon was further away. I don't think there would be any ringed lunar eclipses... If anything, if our moon drifts further away, we'd have ringed SOLAR eclipses. Wouldn't we?

nugglet Says:

I don't get why it would look like a ring
it would just be smaller and dimmer than it is now

Doesn't the shadow get larger as you get further away? Dope idea though.

Nah the source of light, the sun, is much larger than the earth so it could be possible

... That crescent isn't because of the earths shadow. That looks like just a normal crescent moon.

Wouldn't the opposite happen? The farther the object the shadow is cast on the larger the shadow is, so that would mean we would just block out all light from hitting the moon making it appear black. So for the ring to form the moon would actually have to be closer than it is now.
