The moon is the only satellite of planet Earth. We observe it daily in the sky. The moon has a fairly strong influence on the planet and even on the psyche of people. The satellite study has been going on for more than 2,000 years, and continues today. Despite the latest technology, scientists still have many questions. Today we will examine how many times the Earth is larger than the Moon and what would happen if the planet of its faithful companion fell. Let's get started!
The moon is ...
Although the moon has always been considered a natural celestial body, there have recently been suggestions that it was created artificially. The thing is that some objects on the moon seem man-made by scientists.
It is known that the sky above it is always black, the atmosphere is absent, and sounds are not heard at all. Moreover, on the moon there are seas, oceans (created by frozen lava) and even craters. Scientists still care about how the satellite was formed and why it is located where we see it today.
The satellite regularly “3.8 cm” runs away from the Earth. Some scientists even believe that in 50 billion years the moon will simply “run away”. However, this theory does not find support among many other researchers.
It is also assumed that inside the satellite there is a metal core covered with three layers of the mantle and heterogeneous crust, the thickness of which can reach 100 km.
How many times is the earth bigger than the moon?
Scientists have long discovered that the satellite is 6 times smaller than the blue planet. How many times the Earth is larger than the Moon can be seen by looking at the photo. Indeed, visually information is perceived much better. That's how many times the Earth is larger than the Moon in size. The difference is huge!
If you look at the satellite from the Earth, then it seems very small - about 30 cm across. However, if you admire it from the horizon, the dimensions seem more impressive.
The radius of the moon is 1737.1 km. While the average radius of the blue planet is 6371.0 km. Thus, the satellite is 3,667 times smaller than the planet.
How many times is the Earth larger than the moon in diameter (it is equal to two radii)? This figure is 3,476 km. It is in these figures that the distance from Moscow to Tomsk is calculated. As is known, the equatorial diameter of the blue planet is 12 757 km. That is, in its diameter the Moon is four times smaller than the Earth. More precisely, the satellite’s diameter is 0.272 times the diameter of our planet.
How many times is the Earth larger than the moon in area? The surface area of the satellite is 37.93 million square meters. km While the Earth’s area is 510.1 million square meters. km That is, the satellite area is approximately equal to the total size of three countries - Russia, Canada and China.
How many times is the Earth larger than the moon in volume? The satellite is almost 50 times smaller than our planet, that is, it occupies only 2% in space.
The satellite density is 3.34 g / cm³. This is only 60% of the density of the Earth. The difference in density is due to the fact that our planet is larger and its bowels are under great pressure. After all, the interior of the Earth consists of a massive core, in which 32% of its mass is concentrated. While the core of the moon cannot contain more than 5% of its mass. That is, its size is approximately 350 km.
How many times is the earth larger than the moon in mass? 81 times. Newton tried to calculate the mass of the satellite. But as a result, I received data that exceeded the actual 2 times. We remind readers that the mass of any body is characterized by the amount of substance contained in it for a given volume. The more substance inside, the more its weight. Hence, the more efforts must be made to, for example, lift or move it.
The force of gravity on the surface of the moon below the earth is 6 times.
Planet shine
Take into account the brilliance of the satellite. The reflectivity (that is, the luster we see from Earth) of the moon is 3 times lower than that of a blue planet. It follows that the illumination provided by the satellite is 41 times weaker than that of the Earth, if you admire it from space. This corresponds to a difference of 4 m magnitude.
If there were no moon ...
Perhaps without it, life on a blue planet would never have arisen. The change of seasons occurs precisely thanks to the moon. Without it, temperature jumps would be so intense that the African summer could easily be replaced by Arctic cold in one territory. The nights would be much darker than now, especially when we observe a full moon disk in the sky.
Without the moon, earthlings would not be able to admire a unique sight - a solar eclipse. This is because it is located so well that it completely hides the star when it is in line with the Earth.
On the planet, the year would be completely different. After all, the Moon not only controls the ebb and flow, it also slowed down the rotation of our planet several times. Without it, a day would last only 8 hours. Thus, the duration of the year would be about a thousand days.
That is, the moon not only adorns the sky and leads to a romantic mood. Despite the great distance (it takes 3 days to fly), the satellite has a huge impact on the blue planet. Without it, the relief of mountains and plains, life forms would be completely different.
Conclusion
There are many interesting facts about the satellite of our planet. We examined the most interesting of them and found out how many times the Earth is larger than the Moon.
