If you lived on the lunation , you ’d have to give up mint of thing you take for grant on Earth . The feeling of your infantry planted firmly on the ground . Your power to suspire outside without a helmet . And your night - sky view .
Humans have spent millennia stare up at the moon , watching it rise and set , chart its phasesas it grows and shrinks each month . But from the point of view of the lunation , how would the Earth look cling in the sky ?
There would be a sweet view of Earth from the moon.
Well , first , that calculate on where you ’re suffer . [ How Does a Black Hole Form ? ]
The moon is tidally locked with Earth , meaning the moon ’s orbital period rival its rotational period . It takes about a calendar month for both the moon to orbit Earth and for the moon to rotate on its bloc . in effect , this means that the same side of the moon always face our planet . That ’s why when you peer through a scope , the craters and other features on the surface of the moon are always in the same place .
The first humans who straight off saw thefar side of the lunar month , that is , the side that ’s always facing off from Earth , were the Apollo 8 astronauts .
There would be a sweet view of Earth from the moon.
If you were camped out on the far side of the moon , you ’d never have a view of Earth . If you were ground on the near side , you ’d see Earth all the time . And Earth would indeed seem to go through phase over the course of about a month , directly opposite to the lunar phases hoi polloi on Earth would be witnessing , said Phil Nicholson , professor and deputy director of the Cornell Center for Astrophysics and Planetary Science in Ithaca , New York .
Lunar phasesoccur because one - one-half of the moon is alwayslit up by the sun . The calendar month - recollective cycle of full and waning that we see is just the long lunar solar day turn into Nox as the moon orbits Earth .
While Earthlings gaze at a darken new moon ( when the side of the moon facing Earth is not perch up by the sun ) , a lunar observer would be looking at a " full terra firma , " the one-half of the major planet totally illuminated by the sun . Over the following two weeks , moon dwellerswould see a shrinking crescent of Earth until the moon was right away facing the darkened nighttime side of the planet . At that point , Earthlings would be basking in the light of the full lunar month . To a person support on the moon , this full moon ’s muse light ( and peradventure some artificial Christ Within ) might make the unexampled Earth faintly visible .
" It would n’t just look coloured , " Christine Shupla , the educational activity and public engagement managing director atNASA ’s Lunar and Planetary Institute , told Live Science . " You would see potentially lights on the Earth in city . "
Your view of Earth , however , might not be crystal clear . If the part of the moon you ’re on is experiencing day , your observations of the macrocosm might be affected by the sun glaring off your helmet ormoon rocks , Shupla noted . But because the moon has no atmosphere , you would still be able-bodied to look at the stars during the 24-hour interval .
The Earth would also look much bigger than the moon does to us . ( The Earth is about four times larger than the synodic month , in diameter . ) And from the perspective of the moon , Earth would also always look to be in a restore location .

" While the Earth goes through phase , it does n’t in reality move in the sky , " Nicholson separate Live Science . " Itwobbles back and forwardsa fiddling moment because of the lunation ’s elliptical , but it does n’t rise and set like the moon does for the Earth . " So if you were standing in what we perceive as the middle of the lunar disk , the Earth would always look to be directly overhead .
However , from the moon , you would n’t always see the same feature of Earth . You ’d notice dissimilar features as the planet spin .
" The Earth is turn out quicker than the moon , " Shupla said . " Sometimes you would see more oceans and sometimes you would see more continents as the hours go by . "
The doubtfulness also got Nicholson remember aboutwhat sort of eclipsesyou’d see from the moon .
" If you were live on the moonshine , it ’d be easier to see solar eclipse because the Earth is so much self-aggrandizing , " he said . What we call a lunar eclipse ( when the moonshine is in the shadow of Earth ) would be asolar eclipsefrom the linear perspective of the lunar month . These would occur two or three times a year . And when a solar eclipse occur from the vantage point of Earth ( like the2017 eclipsethat was seeable over a big stretchiness of North America ) , mayhap with the service of a telescope , you ’d be able to watch out the synodic month cast its large shadow across Earth .
" You would see a little dark spot , " Nicholson said . " That has really been photographed from range . It face like a small black hole that ’s trying to swallow Earth . "
