What country would be equal in size to the area of the moon?

The moon has 14.6 million mi². The earth, meanwhile, is 70.8% covered with water. What sticks out of the water covers 57.5 million mi². This means there’s only 3.9 times more land on Earth than on the moon. The moon takes up more than 1/3 of the landmass of Earth above water!

Put that in your pipe and smoke it!

No country in the world is as big as the landmass on the moon.

The closest you might come is the biggest country: Russia, with 6.6 million mi², less than half the area of the moon.

Here’s what the landmass of Earth might look like if we stuck it all together.

Do you know anywhere I can move to or go to so I can see the harvest moon at night in the sky every year?

Don’t spend your money! You do not need to go anywhere special to see the harvest moon at night.

The harvest moon is merely the full moon which is closest to the equinox in the autumn. The fall equinox comes around September 22, every year. So which ever full moon is closest either before or after that date will be the harvest moon. You will be able to see that moon anywhere on Earth except maybe near the poles. The next harvest moon will be September 24th, 2018. Look up that night. As long as there are no clouds, you’ll see it. It’s big.fb_img_1486783783855

Why don’t we see the hidden face of the moon? Is this because the moon rotation is perfectly synchronized with Earth?

You are correct. The moon is synchronized with Earth, although not perfectly. There is a wobble which I’ll show you below.

The “face on the moon” means that some people see what looks like a face on the side of the moon we can see. It’s not on the far side, but the side we see.

Here is a picture of the moon with the “face” outlined that people call the “face on the moon.” It is not meant to be comical (though it looks funny), but outlines the moon features people imagine look like a face.

More below the picture.

Now, here’s a comparison of the near and far side of the moon taken by a satellite we placed in orbit around the moon. On the left is the familiar side of the moon we see facing Earth. On the right is the side we never see from Earth because it faces away from us. This shows the moon is tidally locked with Earth so that one side always faces us. More below.

And finally, here’s an animation that shows that the moon isn’t perfectly synchronized with Earth, as you put it (scientifically it’s called “tidally locked”), but wobbles quite a bit from full moon to full moon. Due to this wobble, sometimes you can get a peak of what’s on the far side. You’ll also notice the moon gets larger and smaller in the animation. This variation happens because the moons orbit is slightly elliptical around us, so sometimes it’s a little closer and looks bigger, and sometimes a little further and looks smaller. A full moon when the moon is closest is called a supermoon.


Given that NASA has landed on the Moon, why did they not put some plants on the lunar surface?

Wow. What would have happened if astronauts had brought plants to the moon? Surely by now the moon would be green! Here I always thought the thing was made of blue cheese.

You must know from the other answers that there’s no air on the moon and plants need air to survive just like you do. Another issue is there’s no water on the moon – no rivers, no lakes, no rain – and we all know if plants don’t get water they die.

However, I can offer you what none other can! Below is a picture of what the moon would look like if it really was green!

Which is more difficult to achieve 100 years from now, building a giant telescope to directly observe other planets in a distant Galaxy or building a faster than light space ship?

Faster than light speed will never be possible, ever. The best you’ll be able to do is maybe 1/10th the speed of light given an enormous amount of propellant, and then you’ll have to slow down at the end of the trip using just as much fuel as it took you to go that fast in the first place. There will be no warp drive or something that folds space. These are all convenience devices for story telling on science fiction movies.

Maybe in 200 or 300 years generational space environments will be the way to travel to other planetary systems. A generational space environment is a huge ship that rotates for a sense of gravity inside, where whole generations are born and die over hundreds of years – often resenting that their ancestors trapped them on that ship – to reach far away places.

Your given time frame of 100 years from now is not very far away in the bigger picture, but having a huge telescope on the far side of the moon is possible and would help with astronomical observations.

Will the moon or Mars have the first permanent human population?

In my opinion, hopefully neither place because there is no valuable reason for humans other than our robots to establish a presence in either place. Robots are expendable and you don’t have to bring them back. They can transmit what they find. Both are dead planets. Both have no reason to settle there.

The Moon is not as Close as you Think!

Mercury, Venus, Mars, Jupiter, Saturn, Uranus and Neptune could all fit in the gap between the Earth and our Moon with about 4,990 miles to spare

Think of Earth as a basketball and the moon like a tennis ball. How far would you have to place them apart to approximate the distance between the Earth and Moon? Five feet? Ten feet? Twenty feet? Nope! Further even then that! A tennis ball would then have to be about 24 feet from the basketball to be of the proper scale. Farther than most people visualize.

This is how it looks (See image). Kind of surprising. The moon looks bigger to us than that, doesn’t it? Well, no it doesn’t. Our minds eye just makes it look bigger. Hold your thumb out at arms length. The tip of your thumb at that distance more than covers the moon. Still, the moon is the biggest thing in the night sky, and it really stands out much brighter and bigger than all the stars, relatively.

Surprisingly, people really do think the Moon is closer to the Earth than it is. You can see from the photo taking a “mere trip to the Moon” is no easy task!

Here’s a statistic for you! Think how big Jupiter, Saturn, Uranus and Neptune, the gas giants, are in relationship to our tiny Earth.

Yet our Moon is so far from Earth that Mercury, Venus, Mars, Jupiter, Saturn, Uranus and Neptune could all fit in the gap with about 4,990 miles to spare (using the average Earth-moon distance of 238,555 miles).
