"The sun at its zenith" - what does this expression mean? How to understand that the sun is at its zenith

You can often hear the expression "the sun at its zenith." What does it mean? Where, at what point of the firmament can one see the star at this moment, and how does such a position differ from its other positions and states? What time of day or year does this happen? And, if the sun is at its zenith - what does this mean for the inhabitants of the planet Earth?

The Basics of the Sun

The sun is the closest star to planet Earth, the central celestial body of the system of the same name, which has the shape of a sphere and consists of hot gases with a surface temperature close to 5505 ° C, and in the central part it is heated to 13.5 million degrees.

The diameter of the sun is almost 110 times the size of planet Earth - 1,392,000 kilometers.

Sun from space

Around the Sun there is an atmosphere consisting of three layers - the photosphere, the chromosphere and the solar corona. All radiation, which people can perceive with the help of sight, belongs to the first layer.During a total solar eclipse, you can observe the solar corona, which is several times larger in diameter than its source.

The mass of the Sun is 333 thousand times higher than the Earth’s, but its volume is even greater - 1 million 304 thousand times, which means a lower density of the star’s composition.

The energy received by our planet from the Sun is only a small part of the whole emitted by a star, but it is many times greater than the entire amount produced artificially on Earth.

The sun revolves around its axis in 25.4 twenty-four hours a day that we are used to.

The approximate distance from our planet to the Sun is 149.5 million kilometers, but these values ​​are so huge from the point of view of overcoming that they are measured not by linear units, but temporary ones from the position of light movement. Sunlight reaches the earth in 8 minutes and 18 seconds (its speed is 300,000 kilometers per second).

The entire solar system is constantly shifting in outer space towards the constellation Lyra. The speed of this movement is 20 kilometers per second.

What is zenith?

The sun at its zenith - scheme

Zenith is called the highest point in the sky, that is, when they say that the sun is at the zenith - this means that the light is located directly vertically above the head of the observer.The sun's rays in this case fall perpendicular to the surface of the earth - at a right angle. So, if objects do not cast shadows - this means that the sun is at its zenith.

However, this definition is colloquially applied to the position of the sun, which can only be called the zenith conditionally. Due to the peculiarities of celestial bodies and their position in outer space relative to each other, to fall at an angle of 90 °, the rays of the Sun will not be on every part of the Earth.

The point located on the same steep straight line as the zenith, but in the opposite direction, below the horizon, is called a nadir.

Sun Zenith movement throughout the year

The sun is high in the sky

Since there is a constant movement of celestial bodies relative to each other and its own axis of each, the sun's zenith throughout the entire Earth year all the time moves in the direction from tropic to tropic with a speed roundly equal to 1 ° for four days (more precisely - 3.8), which is in terms of the week will be 2 °. This means that it is very easy to determine how the sun at the zenith will shift in relation to the earth.

Having for the starting point knowledge of the days of the solstice, you can approximately calculate the latitude at which the sun will reach its zenith for any date.

Twice a year, the Sun is at its zenith above the equator — March 21 and September 23 on those calendar days when light and darkness in days are equally divided as the autumn and spring equinox. So in the calculations of the latitude of the sun at the zenith, these are the initial numbers that can be taken as a basis.

For example: calculating the latitude at which the sun will be on Russian Cosmonautics Day - April 12, it is necessary to determine the number of days elapsed from the nearest reference date (this will be the spring equinox on March 21). Between the starting point in time and the estimated 22 calendar days. If the shift of the star by 1 ° occurs in 3.8 days, then in 22 its location will change to 22: 3.8 = 5.7 °. Since in this case there is no need for exact calculations, it is possible to round the obtained value to 6 ° - this is how the angle of the Sun changes relative to the Earth in the direction of its movement north of the equator.

Where on our planet you can see the sun at its zenith

For the convenience of determining the points and positions of objects on a planet scale, the entire Earth is divided horizontally and vertically by conditional lines - the girdles are called parallels, and the equator, located in the middle, is the longest of them.Speaking about the position of a point on the planet with the help of parallels, they use the term "latitude".

Vertical lines - meridians, correspond to longitude. All numerical values ​​of latitude and longitude are denoted in degrees.

Due to the shape of the Earth and the inclination of its axis to the Sun by 23 °, the position of the star relative to our planet, which is defined as zenith, is probably not for every point. For most residents, this phenomenon is not available.

The fall of sunlight at a right angle occurs only at the equator and within the tropics - between the parallels above and below (south and north) of the equator line.

The Northern (named after the constellation of Cancer) and the Southern (called after Capricorn), the tropics conditionally limit the part of the planet above which the sun is at zenith at noon.

On the day of the summer solstice - June 22, the sun at its zenith will be above the parallel called the Northern Tropic, and on the day of the winter solstice, December 21 - over the South. At all latitudes located between them, the position of the sun at its zenith can be observed twice a year.

How the sun at the highest point of the firmament inspires poets

The heavenly bodies, both the one that reigns during the day and the one who dominates the night, inspire people of art to write pictures, music, literary works of various forms.

Among them is the young Moscow poetess, laureate of the Pushkin youth festival "With a Century on a Parity", Kira Tikhonova (nee Danilyants).

The sun is at its zenith

The sun is at its zenith, the coat is in the snow.

Up the street dragging

Sleds, heavy as cast iron,

Glossy runners.

And under the general laughter and screeching

I, accelerating, fly down,

In a bunch of wallowing faces,

Fiery from frost.

Snow in the tundra, children's holiday!

We set up fortresses

We are on the street all day,

In wet through clothes.

We started a snow fight.

We come home in the dark

Hot as a steam room

Although squeeze and hang!

The sun at its zenith, the shorts in the dust.

In a bunch of laughing kids

Red with rust on the steering wheel

Old is great rushing.

Knees in Zelenka, shot down again.

The sun is like in the tropics - thirty-five!

Glad to chase and catch up

Under this scorching sun.

No ipad, no tablet

Before the first computers - ten years.

Childhood, joyful as the light

I remember through the haze ...

The sun is at its zenith. Overalls.

My eldest child with a gloomy face

Snow disgustedly kicked

New boot ...

And a novice author hails from the suburban town of Mytishchi Victoria Vikolskaya.

Sun to Zenith

I love those clear days

When the sun comes to zenith.

And in the morning comes to the zenith,

And in the evening comes to zenith

And not only at noon.

Even if it's jelly outside,

Even if people are cold,

Stroll the sun beckons

Because it comes to zenith!

Light rays shine the world in the morning -

It is very common.

But something all is unusual.

And what is unusual here?

So today, it was yesterday ...

Yes, the very thing here is so unusual:

That the sun doesn’t care

What time in the world.

Let any time in the world -

Rays shine the world in the morning.

I love those clear days

When the sun comes to zenith.

What does it mean - comes to zenith?

It means - there is not a cloud in the sky,

And in the morning there is not a cloud in the sky,

And in the evening there is not a cloud in the sky.

A ray flashing on the glass ...

On a tree leaf ray ...

Ile high powerful slopes

Illuminates that sunbeam.

Even if the clouds frown -

If there is even one ray of light,

That means the days are not overcast.

And if the days are not overcast,

No matter how hard the ray is,

He is stronger than the gloomy clouds!

Because he made his way through the clouds,

Gifted by the sun mighty.

If the ray penetrated through the clouds, -

That means days are not overcast

If there is even one ray of light, -

So the sun comes to zenith!

Suppose this is not quite true from the point of view of science, but it is warm and really sunny.

The sun at its zenith as a symbol

Sun over the sea

In each teaching, based on symbolism, the sun has a special place. In relation to the luminaries as a sign that has an impact on the decoding of dreams, you can find different interpretations in different collections.

If the sun dreamed at the zenith - what does it mean, and how to understand such a vision? Here are a few sleep meanings:

  • satisfied ambition and exhausted (in other variants - limitless) possibilities of the dreamer;
  • a good choice of fans and the successful implementation of a carefully prepared plan for personal prosperity;
  • happiness and rewarded sound ambitions;
  • career advancement;
  • good luck in everything.

It can be said that the sun is capable of pleasing people, warming and giving them their patronage not only during the day, while awake, but also at night, even in a dream. It is not necessary to believe in the subtle links between events and phenomena, borderline scientific knowledge, so that good predictions come true - it’s enough just not to doubt the good and bright things to come.
