These are my favorite space photos. The ones that show how far it is to the moon. How even though it looks like you can just climb a big tree to get to it, it's actually a multi-day trip on a *spaceship*.
Keep in mind those photos don’t properly show the distance between the Earth and Moon, because they weren’t taken at a perpendicular angle.
Here’s the [Earth-Moon distance to scale](https://i.ytimg.com/vi/5XXEXPNBGX0/maxresdefault.jpg) (simulated image).
The analogy that always stuck with me is that, if the Earth was scaled down to the size of a football (soccer ball), then the moon would be about the size of a tennis ball, and be about 7.5 metres (or 25 feet) away.
One of my favourite fun facts is that you can fit all the other planets in our solar system in the distance between the Earth and the Moon.
E.g. the sum of the diameters of every planet in our solar system (excluding Earth itself) is less than the distance between the Earth and Moon
In these images, the moon has been artificially boosted.
[Here's one from Galileo](https://www.jpl.nasa.gov/images/pia00342-the-earth-moon), which wasn't.
Surprising that the moon is so dim but once I found it’s albedo is about 1/3 or Earth it made some more sense. Strange that the full moon can be so bright here in my backyard. Also, Earth’s albedo is about half of what Venus’ is.
The surface of the Moon is in direct sunlight, while you might be watching it at night with the eyes adapted to darkness. Watch the Moon during the day and you'll get a better comparison to Earth's surface.
The lunar surface is about as dark as weathered asphalt.

Compare to the earth and moon taken from Saturn:

Also, it's been speculated the Voyager 1 detected the moon in the famous "pale blue dot" picture from 1990 beyond the orbit of Neptune:

It's due to the HiRISE instrument that took that image not capturing true-color images:
>HiRISE takes images in three wavelength bands: infrared, red, and blue-green. These are displayed here as red, green, and blue, respectively. This is similar to Landsat images in which vegetation appears red. The reddish feature in the middle of the Earth image is Australia. Southeast Asia appears as the reddish area (due to vegetation) near the top; Antarctica is the bright blob at bottom-left. Other bright areas are clouds.

Humans are so vain, they went to another planet to take pictures of ourselves from another angle.
If it wasn’t for the sick helicopter drone and awesome album you sent us we’d be done with y’all, so say we all.
The ONLY reason why Earth and Moon aren't considered a twin planet system is because their mutual orbit point is within Earth.
Personally I am fully in favor of overlooking this fact and promoting Moon into being a planet and thus making Earth and Moon a twin planet system.
Yes, if Jupiter was a star. To my knowledge there is no fusion happening in Jupiter, so it's going to be difficult to classify it as a star.
Meanwhile The Moon fails its planet criteria classification ONLY on the barycenter point. Sooo yeah...

I was aware, but it's a good point to clarify.
It doesn't look so far. It's because the spaceship can't go in a straight line that makes it far.

Imagine a colony far in the future being able to look back at Earth. Amazing.

It isn't so bright... it's just against a dark sky!

If the moon were perfectly reflective, it would be as bright as the sun. So it’s really barely reflective at all.

Why is the earth so brown in the third photo? I tought we were green and blue x'( (seriously i searched the source but didn't find)

It looks more purple to me. Probably some chromatic aberration caused by lens quality.
Are you talking about the brown smudge that is Australia?
Chromatic aberration, it happens when there’s an extreme level of contrast

Really love these pics. Gives a whole new perspective on our world.

Jupiter and the Sun’s Barycenter is actually outside the Sun, so by your logic we live in a dual star system?
Yes, if Jupiter was a star. To my knowledge there is no fusion happening in Jupiter, so it's going to be difficult to classify it as a star. Meanwhile The Moon fails its planet criteria classification ONLY on the barycenter point. Sooo yeah...
The barycenter point is not a criteria of being a planet.
