Is earthlight brighter than moonlight?
- MikeLv 74 months ago
Because the Earth's albedo is about 3 times that of the moon and the Earth is larger in area, the full Earth as seen from the moon would be about 50 times brighter than the full moon as seen from Earth.

Yes it is... Earth's albedo (the amount of light reflected by area) is greater than the moon's, and the area of Earth is much greater as well, reflecting even more light.

Yes. A full Earth is sixteen times larger in apparent area and also reflects more light, being about three times as bright per unit area, so it would average around fifty times as bright. It would be even brighter when it's cloudy or during the Southern summer, when Antarctica is visible.

Yes because the Moon has the Albiedo of a well used roadway

to answer required some INVESTIGATION as to if "EARTHLIGHT" has been measured the terms for EARTHLIGHT are aka PLANET-SHINE or EARTH-SHINE NASA has done measurements that intensity is NOT a constant it varies
for term understanding Planet shine is defined as the dim illumination by SUN-LIGHT , reflected from a planet OR all or part of the otherwise DARK side of ANY moon orbiting a planet
EARTH shine is a dull glow which lights up the UNLIT part of the moon because SUNLIGHT reflects OFF the earth surface back ON TO the moon meaning the same light is REFLECTED TWICE
planet - light is the diffuse reflection of Sun light from a planet whose ALBEDO can be measured and can be observed
EARTHshine( is MOST readily visible a few nights BEFORE and a few nights AFTER a NEW MOON
Leonardo DiVinci explained this phenomenon in the 16th century when he realized EARTH and MOON l reflect SUN light at the SAME time OCEANS reflect the least amount of light 10 %
LAND 10-25% and CLOUDS 50 % may i suggest the book 2 SPACE BORNE measurements of EARTHLIGHT polarization
satellite measurements of ENERGY reflected from the ARCTIC provide a picture of why earth shine PEAKS in SPRING
the MOONS average ALBEDO is 0.12 and the EARTHS ALBEDO is 0.30 the ALBEDO scale of reflection is 0-1 0 being noneffective meaning the moon reflects back 12% of the sun light that reaches it in comparison the EARTH reflects back 30 % of the sunlight that reaches it surface thank you for the question

We can see "earthlight" when most of the moon's face is in darkness. That is two bounces of sunlight--once off the earth, and once off the moon.
There has been no photo of any moonlit Earth as seen from the surface of the moon, as far as I am aware. That would be only at time of the full moon and the earth is near the sun. Too brilliant for exposing the darkened earth with faint moonlight on it.

Moonlight doesn’t actually generate light, it’s simply the reflection of the suns light off the moon.
So it depends on how your asking the question, but the moon reflects more like.
