Planets have no own light. All planets move on its axis. All planets move on its axis towards west to East except Venus and Uranus. All planets revolution the Sun toward West to East. The Satellites revolution its planet. For example, the Earth have One Satellite namely Moon. Saturn have more than 60 Satellite while Mercury and Venus have no Satellite. Some small object revolution the Sun between Mars and Jupiter is called asteroid. The Sun is the core of Solar System. The average distance between Earth and Sun is approx 14 Crore 96 Lakh Km. The Earth is the third planet after Mercury and Venus in the distance from the Sun. The Mercury and Venus are called Inferior Planet because these planet is very near from the Sun. Mercury, Venus, Earth and Mars are called Internal Planet while Jupiter, Saturn, Uranus and Neptune are called External Planet. Venus is more brightener than other planet. Mercury is the smallest planet while Jupiter is the biggest planet. Mars is also called Red planet. The Earth is the only planet in all planets, where is life. All planets orbit the Sun in certain route.
The planets:- There are eight planets in Solar system. The details of planets are given below:-
Mercury:- It is the nearest planet from the Sun. It may seen 2 hours before the Sun rise. It is the smallest planet and it have no satellite. Mercury have magnetic field. Its revolution period is smallest because it is the nearest from Sun.
Venus:- It is the nearest planet from the Earth. It is the brightest and hottest planet. It is also called the planet of evening and the planet of Dawn. It revolution of the Sun towards East to West i.e in anticlockwise direction. It is also called the sister of the Earth because its shape, density and diameter are equal to the Earth. It have no Satellite.
Earth:- The Earth is the third planet in the distance from the Sun and fifth planet in shape. it is the only one planet where is life.The Earth is banned 23.5° on its axis. The equator diameter of the Earth is 12,800 km and its polar diameter is approx 12700 km. It takes 23 hours 56 Minutes and 04 Second to complete one round on its axis with the speed of 1600 km per hour towards West to East. The Earth is also called Blue planet due to presence of Water. Proxima Century is the nearest star from the Earth after Sun. The distance between Proxima Century and Earth is 4.22 Light year. The Earth have one Satellite which is known as Moon.
Mars:- It is also called Red Planet due to Iron Oxide. It have two Satellite namely Phobos and Deimos. It takes 687 days for the revolution of the Sun. Olipas messi is the largest volcano of the solar system which is situated in this planet. The highest mountain of solar system namely Nix Olympia is situated in Mars.
Jupiter:- It is the largest planet of solar system. It have 63 Satellite. Gyanimid is the largest satellite of Jupiter. It is called yellow planet.
Saturn:- It is the second largest planet in solar system. It seems as a yellow star in the sky. The bunch of ring are present around the Saturn. It has 60 satellite and Titan is the largest satellite of Saturn. The shape of Titan is equal to Mercury. The Saturn's satellite Fobbo revolution the Saturn in the opposite direction of the the direction of Saturn's revolution.
Neptune:- It is also called Green Planet. It have 13 Satellite and Triton is one of the important satellite of Neptune.
Uranus:- It is the third largest planet of solar system. It moves East to West on its axis for which Sun rise in Uranus is in west and Sun set in East direction. It have 27 satellite and Titania is the largest satellite of Uranus.
Smallest Planet:- There are following some smallest planet in the solar system .
Pluto:- It is a type of smallest planet. Pluto have no specific feature to become a planet (according to IAU in Prague Summit in 2006) so it is categorized in small planet. Pluto is smaller the Moon in shape. Clyde Tombaugh discovered Pluto in 1930 AD. Pluto is also called 134340.
Ceres, Charon and Iris are also categorized in smallest planet.
Other Object in Solar System:- There are many following objection in solar system.
Comet:- The million numbers of object are present on the corner of Solar System is known as Comet. It is the collection of gas and dust, which may be seen in the Sky as luminous sphere. The revolution period of Halley's Comet is 76 years. It has seen in 1986 last time and next time , it will be seen in 2062 AD.
Meteors:- The dust of comet and the parts of asteroids built a new object, which is called Meteors.
Asteroids:- The objects, which are situated between Mars and Jupiter is called Asteroids. When asteroids hits the Earth then a huge trench creates on the surface of the Earth. Lonar lake of Maharashtra is the example of such trench.
Forwesta is only one asteroids, which may be seen by Human eye.
Other important knowledge about solar system:-
Mercury, Venus, Earth and Mars are called Terrestrial or Inner planet. Jupiter, Saturn, Uranus and Neptune are called Jovian or outer planet. Only five planets (Mercury, Venus, Saturn, Jupiter and Mars ) may be seen by human eye.
The serial number of planet as per its shape ( in descending order.)-------- Jupiter, Saturn, Uranus, Neptune, Earth, Venus, Mars and Mercury.
The serial number of planets as per its density (in ascending order)--------- Saturn, Uranus, Jupiter, Neptune , Venus or Earth and Mercury. The density of Venus and Earth is almost equal.
The serial number of planets (Distance from the Sun)---- Mercury , Venus, Earth , Mars, Jupiter, Saturn, Neptune and Uranus.
SUN:- The Sun is the core of solar system. The Sun is situated approx 30,000 light year from the core of Mandakini Galaxy. The Sun revolves on its axis toward East to West i.e in clockwise direction. The Sun is a gaseous sphere in which 71% Hydrogen, 26.5% Helium and 2.5% other element are present. The part of the Sun which may be seen in the time of solar eclipse is called Corona. The light of Sun arrives Earth in 8 minute and 16 second.
