What Is True North?

 One thing most people don't know is that there are different kinds of true answers.  The axis that the earth revolves around (technically known as a radial vector) is tilted 23.5 degrees from its orbit and perpendicular to the imaginary line extending in all directions from the earth (known as geodesic).  That tilt shifts depending on where you are on earth;  Greenland, for example, is located at about 80 degrees west longitude from Greenwich Mean Time (GMT), which means it measures 20 degrees westward around Earth's orbit when measuring degrees along a meridian drawn north-south.

 What Are Celestial Objects?

 All objects in our solar system are called celestial bodies.  They include planets, moons, comets, asteroids and distant star systems as well as their component parts (i.e., satellites).  All these cosmic objects revolve around a common center of mass known as the barrister.  The Sun is in or around a focus of an elliptical orbital pattern that determines the position of the Earth in our galaxy.  Sometimes when the Earth passes through interstellar gas clouds we see meteor or shooting star lines across our night sky.  Most of them are so far away from us that they seem to be fixed points in space that do not change over time but many of the stars' own orbiting planets are obscure to us without technical assistance.

 How to Locate Celestial Objects

 There are two ways to detect celestial objects: look for them in a constellation or look for their movements.  The easiest way to find objects in a constellation is to use a telescope.  Once you find a constellation where there is an object you are looking for, simply trace its outline until you reach your desired goal.  There are many apps available on iPhone and Android devices that also make it easy to identify stars.  Many of these apps include interactive star maps that will give you information about where the various celestial objects are related to each other.

 How Do You Read the Positions of Celestial Objects?

 We were all there: standing outside at night, slowly flowing across our horizons like a bright star.  But have you ever wondered why some of them move to one side while others seem to move aimlessly?  Why is the moon always in the same place as the earth's horizon?  What about these constellations - do they really look like descriptions of their names?  The mystery lies in understanding how different cosmic objects actually move through space.  Although it may take a few years for us to fully understand, there are many interesting patterns that follow heavenly objects that make them easier to understand.

 How Do We Experience Motion in the Night Sky?

 Let’s start with a question that may seem quite strange: why do we feel any motion?  Wouldn't it be easier to think about things like now and even think about what they were or will be in the future?  Well, first off that would be annoying.  But there is another reason why all the objects on Earth (and everywhere else in our universe) travel through space - this is Newton's law.

 How Do Seasons Occur on Earth?

 The Earth's orbit around the Sun is at an angle (or tilt) compared to the plane of its revolution.  When it is closest to the Sun in its orbit, in late January or early February, it is called a perihelion.  At that time, which coincides with winter in some parts of North America and summer in other regions, we have a solstice.  A solstice is when the axis of our planet points in a different direction than usual - either closer to our nearest star or farther away.  As it turns out, this phenomenon explains a lot about why seasons exist on Earth.

 Seasonal Astrology

 Although astrology does not have a universally accepted definition, it is commonly used to describe a set of beliefs that claim that human things are related to changes in celestial objects (stars and planets).  Astrologers cast horoscopes based on the position of this body.  They believe that human personality traits are determined by the date of birth.  Astrologers also claim that astrological events have led to significant historical events;  For example, they say that astrology predicted the genocidal reign of Adolf Hitler as German leader in 1933.

 Why Does it Matter, Which Way is North?

 Although you can certainly stand up now and point north with a high degree of accuracy, in reality it is very difficult to know exactly where the answer is.  You probably know that the earth rotates on its axis as it travels around our sun.  And since space is large (really large), there are multiple ways to rotate in space without infinity — the Earth has an axis that is tilted about 23.5 degrees relative to the plane of its orbit around our Sun (eclipse).  Since we are accustomed to detect which path to the north based on which side of the earth's axis (straight up), when the earth tilts that direction looks different at different times of the year!

 Zero Degrees Longitude, aka Prime Meridian

 The zero-degree meridian longitude on Earth is located at 0 ° or 180.  Particularly important for navigation on the main meridian;  Indeed, when navigating by latitude and longitude, it is generally assumed that a reference position is given as a source to determine these coordinates from which all positions are measured relative.  This key point was formerly known as Greenwich Mean Time (GMT), but is now known as Universal Time (UT).  Note that there is no official ratification of the so-called Prime Meridian by any international authority.

 Mapping Time Through Space

 Imagine your favorite places on earth — the natural wonders you have seen, for example.  Next to each place, write down what happened there on a typical day.  The sun rises at different times in different places;  Night falls;  People start their day;  Some wildlife became active.  You’ll probably see a lot of consistency between what you see in these examples: people wake up around 7 or 8 in the morning, depending on where they are (or the tendency to go to sleep);  They spend their mornings at work or school activities;  They stop working around noon and start spending more time outside until it gets dark again.  And if you look at the whole earth in more detail, you can notice that the seasons in most parts of the planet move in a predictable way.
