SOLAR SYSTEM

The sun and its surrounding planets are called sunsets. Sun's gravitational appeal is primarily controlled by the movement of the circled planets and other aeronautics.

Currently there are eight planets in the Solar System. These particles rotate the sun on an elliptical path.

Sun 

• The Sun is a self-contained substance at high temperatures.

• The Sun is made by a large amount of hydrogen-containing gases. This is the nearest galaxy.

• Its mass is approximately 1.989 × 10^30 kg. The radius of the Sun is approximately 6.95 × 10^8m. Sun from the Earth 1.496 × 10^11 m. Is in the distance. This is an astronomical unit (AU).

• The Sun's light, the Earth arrives at 8 minutes 20 seconds.

• The gravitational force is 28 times as terrestrial as the Sun's surface.

• The Sun revolves around the East from the east. Its rotation period in the polar region is 34 days and 25 days in the meridian area.

• The center area of ​​the Sun, known as the photosphere, is the bright plate at 14 × 10^6 K.

• The outer surface area of ​​the sun at 6000 K is called chromosphere.

Planets 

Our solar system consists of eight planets, moons, small planets and tail fish. These are all around the sun. Mercury, Venus, Earth, Mars, Jupitor, Saturn, Uranus and Neptune are eight planets.

• Only the sun emits light. All the moon, including the moon, echo the sunlight.

•  On August 27, 2003, Mars was very close to Earth and we could see it well. This will happen again in 2287.

• We say the object around the planet is called moon. Our solar system has all the planets except for Mercury and Silver.

• Any soliloids in the Solar System will not automatically light. They reflect the sun's light.

Venus and Uranus marked with the (*) sign rotate from east to west.

All other planets rotate from the west to the east.

Planetary movement

• Greek astronomer Ptolemy created the geo-central policy of the first principle of planetary movement.

• According to this principle, Thalamy's claim that all the planets, moon and stars surrounding the Earth in the center of the galaxy, are centered around different orbits.

• Ariyappatur, the best mathematician and astronomer of India in the 5th century, said that the planet was rotating on its axis. Since there is no communication between the Orient countries and the Upper Countries, his opinion is not to reach the top scholars.

• Polish astronomer Nicholas Copernicus told the new policy of solitary central policy. According to this principle, all the planets are roaming the sun in the retreats.

• The Danish astronomer Tygo Braye recorded the most accurate footage of the planetary movement. German astronomer Johannes Kepler carefully analyzed his visual records, and embodied the number of planetary motion (empirical).

Other objects in the Solar System

i) Asteroids

Mars and Jupiter's orbits around the Sun are small asteroids that are surrounded by the sun. Due to the gravity of the Jupiter, fragments of the broken planet are small planets. Approximately 1600 asteroids rotate the sun.

ii) Dwarf planet

• Pluto, Ceres, Eris, Makemake,Havmia, etc., were newly classified as Dwarves in 2006. These are also around the sun.

• These are very small. That's why they are smaller than the moon.

Ceres - invented on January 1, 1801. It was classified as a groove for half a century, and then classified as a tiny, and eventually classified as shorts on September 13, 2006.

Pluto - discovered on February 18, 1930. It has been considered for 76 years. Sorted as a tune on 24 August 2006.

Havmia - discovered on December 28, 2004. Separated on September 17, 2008.

Ares - discovered on January 5, 2005. It was reported in the media as 10th. It was announced as a shadow on September 13, 2006.

MacMack - discovered on March 31, 2005. Sorted as a tune on July 11, 2008.

iii) Comets

• The rock is surrounded by water, ammonia and methane. These are easily volatile.

• Comets come around the sun in long elliptical paths. They are far from the sun at most of the time.

• Comet to the solar radiation, when the comet approaches the sun, evaporates approximately 10000 km diameter. The tail that appears on the comet will always be in the direction of the sun. Some comets can be found at specific time intervals.

• Halley's comet is a regular interval. It was found in 1910 and 1986. We can see it again in 2062.

iv) Meteors or Shooting stars

• Comet is broken down into small pieces when the comet closest to the sun. When the Earth's orbit interferes with the comet's orbit, broken pieces fall on the Earth. Most pieces are burned due to the friction of the Earth's atmosphere. Whether they are sneezing or burning. In the clear and unstable sky, we can see these fossils.

• If the comet's broken pieces are larger, the Earth's atmosphere will be able to withstand the heat from the friction of the Earth's atmosphere, and the entire surface of the Earth will reach the surface. They are called intricacies.

• Craters are formed by a large number of climates colliding in the Moon, Mars, and Moon surfaces.

v) Moon 

• It has many names, such as the moon, monday, moon and moon. Moon is not in the planet. The moon does not directly roll the sun. It's just the earth. So the moon is called a satellite. It is one of the largest solar cells in the Solar System.

• An average 27.3 days to round the Earth in an elliptical path. Take yourself 27.3 days. That is why the moon's side can not be seen. There is no atmosphere in the moon. Moisture is on the moon but there is no water in liquid.

• Craters are formed by landslides (or) cracks in the environments of the Moon.
