If a lunar eclipse were being observed from the earth , what would an observer on the Moon see?

Answer 1

The lunar eclipse occurs because the earth gets between the Moon and the sun - the darkness that creeps across the moon's surface is actually the earth's shadow. Therefore, if you were on the moon, the earth would come between you and the sun, and it would look like a solar eclipse.

Answer 2

A lunar eclipse occurs when the Moon passes through the shadow cast by the Earth. If you were standing on the Moon during such an event, you would see the Earth cover up the Sun.

In effect, you have the following relationships:

A lunar eclipse as seen from Earth will be a solar eclipse as seen from the Moon.

A solar eclipse as seen from Earth will be a 'terrestrial' eclipse as seen from the Moon (that is, you'll see the Moon's small shadow on the Earth).

Answer 3

You will see the unlit side of the Earth, with a reddish ring around it caused by the atmospheric diffraction of the sun's light.

I'd be interested to hear anyone who knows how dark the lunar landscape would become for someone on the moon.

Answer 4

agree with the 'lunar/solar eclipse' idea, of course, but.... would the 'apparent' size of the Earth match that of the Sun so that they would be nearly equal in size like they are on Earth?... thus, giving the corona effect there, too?...

Answer 5

They would see the sun disappearing behind the earth and then the landscape around them would be lit by a ghostly red light as sunlight is refracted through earths atmosphere giving it the colour red...
