What does it look like to look at the Earth from the Moon, is it looking up or down?

Looking up, of course.

Is there any difference between looking at the Moon from Earth and looking at the Earth from the Moon? It's just a big one and a small one.

The Moon is seen from the sky from the Earth, and the Moon is seen from the Earth, because the ground is always below because of gravity.

Looking at the Earth from the Moon, the Earth is a semicircle; Because of the Moon.

and the earth are cross-referenced. The moon cannot be divided into upper and lower levels, and there is a vacuum around the moon, so it can only float on the moon.

The earth is in the sky, and you say that the earth is in the sky, whether to look up or down. Since one side of the Moon is always facing the Earth, there is no question of the Earth rising in the east and setting in the West when viewed from the Moon, and the Earth is always stationary.

The Earth is so big for us that it is almost impossible to see with the naked eye what is happening in a short period of time, but for a long time it is moving. The rotation of the Earth is invisible on the Moon, because the Moon is a satellite of the Earth, and it has been revolving around the Earth, and its own rotation. The Moon is rotating as it orbits the Earth in 28 days.

It's like looking at the moon from the Earth, two times larger than the moon. Telescopes must be able to observe the Earth with a resolution of meters.

This way, if your field of view is narrow enough, you can see objects on the ground moving quickly. For example, if you look at the equator, you can see a speed of more than 400 meters per second. No such telescope has yet been built.

Since the Earth's axis of rotation is at an angle (not perpendicular) to the Earth's orbit around the Sun, it should be possible to know the Earth's motion by observing the changes in light and shadow at the north and south poles. However, it is not easy to observe the Earth from the Moon: once you turn to the sunny side, the surface of the Moon will be very hot and the sunlight will be very harsh.

And the moon is always facing the Earth on one side and the other on the other. At the moment, only low-Earth orbit reconnaissance satellites have a resolution in meters and can see the type of car. But geostationary satellites can't see cars.

Low-orbit satellites have fast cycles, so they can't keep their eyes on one place all the time. That's why there are so many satellites, but you still need reconnaissance aircraft. Although we are standing still on the ground, we are relative to the earth and are not absolutely stationary.

Because the molecules are in permanent motion, the earth is constantly rotating and turning, so there are four seasons and a 24-hour day.

The above is a detailed interpretation of the problem, I hope it will help you, if you have any questions, you can leave me a message in the comment area, you can comment with me, if there is something wrong, you can also interact with me more, if you like the author, you can also follow me, your like is the biggest help to me, thank you.

If you stand on the moon and look at the earth, you will see that the earth is rotating, but you can only see that the earth is rotating, not orbiting.

If you hold a position on the moon, you can see that the earth is rotating.

Since the rotation and revolution of the moon are exactly the same, when you look at the moon on the earth, you can only see one side, and this side is not half of the moon, in fact, you can see 68% of the area of the moon when you are the most. If we go to the front of the moon and see how much of the earth can we see, the answer is half or more. This part of the area is the size that you can always see, and if you want to see the rest of the earth, then you have to wait until the earth turns, so that you can see the rest of the earth.

You just have to stay a little longer, and you can see all the places on earth.

This is because the rotation period of the Earth and the Moon is different, and the rotation period of the Moon is the same, and only one side always faces the Earth. But the Earth is not, and the rotation period of the Earth and the Revolution of the Moon are not the same.

The Moon is orbiting the Earth in an elliptical orbit with a speed of kilometers per hour, which is the rotational speed of the Moon, and it takes days to revolve around the Earth. The rotation period of the earth is 23 hours, 56 minutes and 4 seconds, and it can be seen here that the rotation of the earth and the cycle of the moon around the earth are very different, if this cycle is the same, then they will face each other forever.

Because the Moon is always facing the Earth, if you stand on the front side of the Moon, face the Earth. At this point, we can assume that the Moon is stationary, (anyway, the motion is relative, and it is enough to use the Moon as a reference to the virtual system). Then it takes 24 hours for the earth to go around once, as long as you stay on the moon for 24 hours, it is theoretically equivalent to you going around the earth of Qing Jensen, of course, you can see all the places on the earth.

You don't actually have to stay for 24 hours, because it's so far away, you see half of the planet first, and when you turn to the other side of the globe in 12 hours, you can see the other half.

So we don't look at the moon from the earth to the same as we look at the earth from the moon. If you look at the Moon on Earth, you feel that it is not rotating, but not on the Moon, the Earth is rotating. This is related to the rotation period of the Earth and the revolution of the Moon.
