Scientific questions Can anyone tell me about the sun and the earth

The angle between the orbital plane of the earth and the orbital plane of the earth's rotation (equatorial plane) is called the yellow-red angle (23 degrees 26 minutes).

Due to the existence of the yellow econjunction, the direct point of the sun during the rotation of the earth is at the Tropic of Cancer (June 22), to the equator (September 23), to the Tropic of Cancer (December 22), back to the equator (March 21), and back to the Tropic of Cancer, and so on.

Take the Northern Hemisphere as the full example).

During the spring and autumn equinoxes, the direct point of the sun is on the equator.

On the summer solstice, the distance between the Earth and the Sun is the greatest [aphelion]. But we should note that this is the point of direct sunlight at the Tropic of Capricorn! At this time, the northern hemisphere is the summer half year (of course, the southern hemisphere is the winter half year), which can also be understood as the summer we usually call!

On the winter solstice, the direct point of the sun is at the Tropic of Capricorn [the distance between the sun and the earth is the smallest, perihelion], the southern hemisphere is in the summer half, and the northern hemisphere is the winter half year (the northern hemisphere can be understood at this time as we usually call winter).

And the changes in the seasons on the earth can also be explained from here!

Hope it helps!

sorry.

I just said it wrong. It should be the angle between the Earth's orbit and its own equator that determines the four seasons.

The Earth is the axis and its own orbit is not perpendicular. So there will be different angles when the sun is moving, if the northern hemisphere is tilted towards the sun, then the northern hemisphere is summer, otherwise it is winter, and the southern hemisphere is the opposite.

A new Planet Nine has appeared.

1. Pluto.

It was once recognized as the solar system.

But in 2000, astronomers discovered a new object at the edge of the solar system, which is increasing in size, so experts downgraded Pluto to a dwarf planet.

This is mentioned in Why Pluto Was Removed from the List of Nine Planets.

Researchers examined Neptune.

of outer space, Kuiper Belt.

Carried 6 small cold stars. They found that all of these stars have elliptical orbits, and their orbits are all skewed in the same direction. The researchers explained that it could be an unknown planet.

It could be the ninth largest planet in the solar system. The planet's gravitational pull causes the entire solar system to sway, and he is responsible for the swaying of the orbits of these stars.

3. Dr. Batygin says there is no other model that can explain these strange things with high orbital inclination. Unless the ninth planet provides additional gravitational pull, it is not in line with celestial motion.

Law. 4. Regarding the ninth planet, astronomers believe that the mass and size of this distant star may not be small, which could explain the anomalies in the asteroids at the edge of the solar system and the outer ice of Neptune. At the same time, it is very distant, and its huge orbit means that it takes 10,000 to 20,000 years to orbit the sun.

At the same time, its appearance may also help humans understand the origin and evolution of the solar system.

At the edge of the solar system there is a pink planet

1. Few planets are brightly colored, but Scott Shepard, an astronomer at the Carnegie Endowment for Scientifics, discovered a wind-red dwarf star at the edge of the solar system.

Named 2012VP113. With a diameter of 450 km, VP 113 in 2012 is located on the outer edge of Pluto's solar system. Scientists used to think there were no planets there, but this pink star has refreshed scientists' knowledge.

A strange thing found at the edge of the five solar systems, a pink planet revolving around the sun (one circle in 1100 years).

2. As for why it is pink, it is made up of pink ice and rocks, and it moves slowly around the sun. The planet is in the solar system and in outer space.

The second celestial body was discovered between the mysterious region known as the "Neolt Neon". Astronomers believe that there are thousands of previously unknown objects orbiting the Sun, perhaps far from it.

The phenomenon of black holes at the edge of the solar system occurs regularly, and we humans have been studying and observing the solar system, but black holes have always been a mystery that human beings have not been able to solve so far.

At the edge of the solar system, there will be solar wind and sunspot movements. The edge of the solar system generates tremendous amounts of energy every day. According to our current science and technology, many things are undetectable.

The third peculiarity is the powerful protector of Jupiter, the solar system is a galaxy with a very high number of asteroids, the asteroid belt between Mars and Jupiter, the Kuiper belt at the edge of the solar system, and the outermost Oort nebula.

The giant blue star can fit several Earths.

To put it simply, in the universe, the sun is the existence of a star. The relationship between the sun and our earth is that our earth depends on the sun, otherwise there would be no life.

Sunlight is still the same light emitted by the sun, but it changes when it is closed in the earth's environment, it is a very simple change, that is, it is partially absorbed by the atmosphere, dust, objects, etc., emitted, and finally emitted into our eyes to form the so-called sense of seeing. So it's not that there's no sunlight in space, it's that the sunlight there is purer, and maybe there's nothing reflected to your eyes in the vertical width, and you can't see it, and of course looking directly at the sun is another matter.

The energy released by the sun is eventually converted into radiant light and propagated, and as for who can receive it, it depends on the ability of each planet itself

It is not clear what the structure of the atmosphere of other planets is, anyway, the earth's atmosphere is fully functional, not only can absorb the sun's radiated light, but also convert the light into heat energy for the use of all things on the earth and human beings, the earth's atmosphere.

How many functions there are, that's what scientists are studying, but that's not the case anyway.

Solar systemThe range is 2 light-years large, and there are eight planets and many moons orbiting the sun, and the heat emitted by the sun, whether it is radiating light, is all in the service of the system.

As for the remaining space that cannot receive light and heat, it is because it is a vacuum zone, and the vacuum space does not absorb any light and heat, mainly because there is no excessive material absorption, so it seems cold, and it is with their coldness that there will be the warmth of the planets and moons.

Why, if the vacuum also absorbs light and heat, or absorbs all the energy released by the sun and the afterglow of radiant light

So what about the planets, it's not about drinking the northwest wind, isn't this the reason, let's talk about the universe and the galaxies.

All have their own certain laws, which cannot be changed, otherwise how will the universe survive and expand, and how will galaxies develop.

The Sun is a large burning canopy fireball made up of hydrogen and helium, about 149.6 million kilometers away from us, and the Sun is the star, and the Earth revolves around the Sun along with eight other planets.

The first point is that the sun is so exciting and real, it has a lot to do with the earth, because we are all part of the solar system, so there is a sun to have our hungry life, the second point is that the sun and the earth are related to each other, so no one can be separated from the bad luck.

The Sun is a star and is the center of the entire solar system, and the Earth is the third planet of the Sun, revolving around the Sun for one revolution.

At present, human vehicles have landed on the moon and Mars, and Kinkishin will land on more planets in the near future. In the entire Taisha Burning Sun system, the Sun is the largest and most dazzling planet. If someone says they want to land on the sun, I think many people think it's a fantasy, and even think that this person is crazy.

Not to mention the internal temperature of the sun, the temperature of its surface alone is as high as 6000, and the metal with the highest melting point on the earth is tungsten, which can withstand 3415 high temperatures, and even then it is evaporated before it is close to the sun. The closest man-made vehicle to the Sun is the Parker Solar Probe, which can only be seen from a distance of 24 million kilometers from the surface of the Sun.

However, some scientists do not believe that the interior of the sun must not be able to land, because the previous assumptions are that the interior of the sun is carrying out nuclear fusion, and if it is not carrying out nuclear fusion, then the temperature inside the sun is not as high as the surface.

We know that the highest temperature on Earth is the thermosphere and exosphere, some places as high as 2500, and then we humans can live well in the interior of the earth. In addition, the clouds above the earth produce lightning, which means that the surface of the earth is actually glowing, what is the principle of this?

In this regard, the Swedish physicist Hannis Alvin proposed the "plasma universe theory", and this person won the Nobel Prize in the study of plasma physics. He believed that the inside of the sun was empty, and the whole was a plasma universe, and the outer clouds were a plasma, constantly "lightning" and "heating".

In addition, Norwegian physicist Christine Beckland also put forward the theory of Buckland current, believing that the so-called Buckland current will produce a strong electric field when it encounters a dense substance, which can also be verified in the earth's current layer. The density of the sun is the highest, and the combination of the two causes the temperature of the sun's surface, and they think that if the earth could be as big as the sun, then the earth's surface would be the same as the sun as they see it now.

In fact, this theory is still there, because humans have not been inside the sun, so there is no way to know if nuclear fusion is taking place inside. All in all, many of our current mysteries of the universe are still based on hypotheticals, and many phenomena are not yet definitively answered, and if the internal structure of the sun is similar to that of the earth, then it is not impossible for humans to land on it.

First of all, there are streams of photons and neutrinos between the sun and the Earth, mainly nuclear fusion radiation and blackbody radiation emitted by the sun.

Secondly, gravitons directly exist in the sun and the earth, and gravitons transmit gravitational force, but the existence of gravitons is only predicted in theory, and there is no way to observe it through practice.

Then there are gases and dust directly on the Sun and Earth, and this is mainly ejected from the solar corona or other lead activity, as well as interstellar material drifting from the universe.

Again, dark matter exists directly on the Sun and Earth, and dark matter is widely present in the Milky Way, but its density is also very low, and it cannot be directly observed, and can only be observed indirectly through stellar orbits and gravitational lensing.

Finally, the vacuum is not empty, there are quantum fluctuations in the vacuum, and virtual particle pairs will be randomly generated in the void and annihilation will occur immediately. The Large Hadron Collider can use this property to discover new particles. Thus the vacuum contains all the elementary particles.
