Universe

 The universe originated 13.7 billion years ago today with the Big Bag event.  Which was stated by the Belgian astronomer Ab Jorge Lamtre.

  Why did Claudius Ptolemy begin the regular study of the universe in 140 AD?  He believed that the earth was the center of the universe and that other planets, including the sun, orbited it. 

In 1543, Copernicus first named the sun the center of the universe.  But the concept of the universe was limited enough by the solar system.  All the celestial bodies, meteors, galaxies, the entire celestial body are studied within the universe.  The diameter of the universe is 10) light years.  The universe is made up mainly of numerous galaxies.

                   Constellation

The constellation is a constellation of stars, named after its distinctive and systematic works.  So far 89 constellations have been identified.  Hydra is the largest constellation.

  A black hole is a stationary extreme gravitational field at the center of our galaxy that does not allow light to pass out of its own gravitational field.  Light travels a distance of 3 lakh km in 1 second.  1 light year 9.4X10 km.

                   Solar System 

* The collective family of the sun as well as planets, asteroids, meteors, etc. is called the solar system. 

* The Sun is 30,000 light years away from the center of the galaxy,

The Sun, as well as other stars, travel through the orbit around the center of the Milky Way.

  It takes the Sun 25 million years to complete one revolution around the Madhas Ganga.

  Which is called the cosmic year.  Its speed is 250 K seconds.  The sun is the star.  From which I have derived.  

Surya is the father of the Sor family.  Happily from east to west he does on his fairy.  

Rotation period 25 days 5 hours Its surface temperature is 600 / c.  And the temperature of the center is 5 crore, it is a ball of air.  Of which 7 are choidrogens, 26.5% helium and 2, others are mine.  Its source is its nuclear fusion.  

In which hydrogen is converted to William.  Basar 18,000 km.  (1% go than the earth) The sun's mass is 4 times greater than the water.

  It takes 8.5 minutes for the sun's rays to reach the earth.  The surface of the sun is called the photosphere.  

There is no light at the edges of the photosphere so the atmosphere of happiness absorbs the light.  

Vomit it !.  Commodia) is karmavaya.  Which is red in color.  The black spots or pits that appear on the surface of the sun are called sun stains.

  It is a black hole on the surface of the sun and its temperature fluctuates.  Which passes over the earth every 5 years.  Meanwhile, the temperature in the east rises.

  The aurora borealis on the northern hemisphere and the large mottalis on the south. 

 The garden where the sun appears at the time of solar eclipse is called Korona.  

Who breeds alcohol.  It is also done for the sun.  A complete sunscreen is a means of burning what is in the sun.  In the black line seen on the surface of the sun, the age of the monocar line is billions of years.

                       A. Planet:

 A A. Planet: A planet is a body orbiting the sun.  Which are derived from the sun.  Which is illuminated by sunlight and receives heat from the sun.

  • Jupiter is the largest planet.  While Mercury is the smallest planet.  The definition of a planet was defined at the IAU (International Astronomical Union) 2006-11 HPL convention.  According to which the celestial body orbits the sun.  
The planet has enough gravitational force to make it spherical. is a body orbiting the sun.  Which are derived from the sun.  Which is illuminated by sunlight and receives heat from the sun. 
 • Jupiter is the largest planet.  While Mercury is the smallest planet.  The definition of a planet was defined at the IAU (International Astronomical Union) 2006-11 HPL convention. 
 According to which the celestial body orbits the sun.  The planet has enough gravitational force to make it spherical.
- • There is no abundance of astronomical objects in the surrounding area and no orbits of other planets.  According to this definition, Lotto is excluded from the range of planets.  Because Scuto was even smaller than its satellite, the circular orbit was not appropriate.  Traditional planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Netrun
 • Dwarf Plant: Dwarf Plant: Scuto, Ceres, Session, 2003uv313 
• Other objects: Comets, satellites, asteroids, meteors.  The planets are divided into two parts.  1) Inner or Terrestrial Planet: Mercury, Venus, Earth, Mars (because they are similar to Earth.) 8) Outer Planet or Jovian Planet: Jupiter, Saturn, Uranus  , Ne ... no.
  3) All the planets revolve from west to east except Venus and Uranus.  yuan penal 1) Mercury (Merecury): 
• It is the closest, smallest and fastest planet to the Sun.  Its distinctive feature is the presence of its magnetic field.  There is a lack of atmosphere. 
 Its light is golden. Seen from Earth two hours before sunrise.  2) Venus:

                       B) Satellites 

These celestial bodies orbit the Sun, including their respective planets.

 Unlike the planets, they are not self-illuminated but are illuminated by light.  

Mercury and Venus have no satellites.  

Most satellites orbit like their own planet.  But the orbits of 10 satellites are opposite to their own planet.

  • The moon is the satellite of the earth.

         Other Solar System Asteroids 

There are thousands of celestial bodies between the orbits of Mars and Jupiter, which orbit the Sun.  They are known as asteroids.  It has asteroids with a diameter of 1 km to 5000 km. 

 Came into existence as a result of the explosion of the planets. 

 The first asteroid was discovered by Italian astronomer Piaget.  Palasa, Juno, Vesta etc. are the main asteroids.  Char Vesta is the only asteroid that can be seen with the naked eye.  Asteroids sometimes collide with Earth. 

                               Comet: 

O is a mass of space dust, ice, gases.  Which roam in cold and dark areas away from the sun.  After many years, when the sun passes close by, the heat causes its air to heat up and the tail appears to be illuminated at the back.  These tails are often millions of km long.  

Hence it is also called the tail star.  Haley's comet can be seen approaching the Sun in 19 years.  First appeared in 1910 and then in 1986.  Will now appear in 2062.  

A comet passes close to the sun every three years.  The cosmic comet appeared in 1974. It will now appear 75,000 years later.
