Quick revision notes

Solar System 


The sun, nine planets, satellites, space rocks and meteoroids structure the nearby planetary system. 

The Sun 

The sun is in the point of convergence of the nearby planetary system. 

It is involved hot gases. 

The sun is around 150 million km away from the earth. 


There are nine planets in our nearby planetary system. 

Mercury, Venus, Earth, Mars, Jupiter, Uranus, Neptune and Pluto are the nine planets. 

Planets move around the sun in a fixed circle. 

Mercury is the nearest planet. 

Pluto is the farthest planet. 

Another planet 2003 UB313 has been found. It is more prominent than Pluto and is farthest from the sun. 


It is the third nearest planet to the sun and fifth greatest planet of our close by planetary gathering. 

The earth is an excellent planet since it supports life. 

It is furthermore called the blue planet. 

Its shape is Geoid. 

The Moon 

It is the primary satellite of the earth. 

Its separation across is one-fourth of the earth. ‘ 

It is about 3.84,400 km away from us. 

It moves around the earth in around 27 days. 

Only one side of the moon is perceptible to us on the earth. 

The moon has neither water nor air, consequently, no life exists on the moon. 

Space rocks 

They are different little bodies which move around the sun between the circles of Mars and Jupiter. 

The greatest space rock is the Ceres


The small amounts of rocks which move around the sun are called meteoroids. 

Our nearby planetary system is a bit of the Milky Way world. 

Smooth Way world was named Akash Ganga. 

There are an enormous number of grandiose systems that make the Universe. 

The Stars and the MOON are sublime bodies which are observable just around night time in the sky. During daytime, the force of the sunlight renders them impalpable. 

The moon shows up contrastingly on different nighttimes—like the Full Moon just once every month, on the poornima night however on the fifteenth night starting now and into the foreseeable future, there is no moon in the sky (amavasya). 

Some awesome bodies are huge and hot since they are made of gases. They are called Stars. The sun is also a star. We don’t feel the glow and light of the stars other than the sun since they are especially far away from us. 

Social occasions of stars that are recognizable in unmistakable models are called Constellations. Ursa Major (the Big Bear), The Small Bear (Saptarishi, etc are some remarkable star groupings. 

The Pole Star is known to hold a comparative position every night in the sky. It is moreover called the North Star since it helps in knowing the North heading. 

Divine bodies don’t any glow and light. They reflect the light they get from stars. Such bodies are the Planets. We live on the earth, a planet. Most planets have Satellites, which are divine bodies that pivot around a particular planet. The moon is the fundamental satellite of the earth. 

The earth and moon are a bit of a more noteworthy structure (or gathering) of divine bodies, called the Solar System. The sun is the “head” of this system and is accessible at its center. The planets turn around the sun, while the satellite pivots around the placets. The planets, despite turning around the sun, furthermore turn about their own rotate. 

The sun is made of exceptionally rankling gases, and it gives warmth and light to the rest of the close by planetary gathering. It is around 150 million kilometers from the earth. 

All the planets of the close by planetary gathering are given underneath: 

Mercury (planet closest to the Sun) 








To hold the names of the eight planets in the solicitation for their great ways from the sun where the beginning of each word is proportional to the chief letter of the planet existing at that position in the solicitation (check the overview above) 

Till August 2006, Pluto was moreover a planet. In any case, it is directly seen as a “prevail planet”. 

The condition of the earth is known as a Geoid. This suggests it isn’t totally round, since it is smoothed at the posts. The earth is likely the principle planet that can reinforce life. This is in light of the fact that its temperature, resources like water and oxygen, etc are accessible in the degrees appropriate until the end of time. The earth, with its 2/3 rd of surface made sure about with water, appears to be blue from space and is called Blue Planet. 

The Moon’s width is 1/4 th of that of the earth. It is 3,84,400 km away from earth. It completes a steamed around the earth in around 27 days. Suddenly, it furthermore requires around a comparative exertion for a rotate about its own center point. It doesn’t support life. 

There are a couple of other little bodies in space (the Asteroids) that move around the sun. There is a “belt” of such things, called the Asteroid Belt, among Mars and Jupiter. 

There exist small amounts of rocks (Meteroids) which also move around the sun. 

There are numerous other minuscule bodies in space (the Asteroids) that spin around the sun. The Asteroid Belt is a “belt” of such items, existing among Mars and Jupiter. 

There exist little bits of rocks that move around the sun (Meteroids) . 

The Milky Way is the cosmic system (a gigantic plan of billions of stars) we live in. The Milky Way is further a bit of a more prominent collection of enormous systems, called the Universe, (suggest Flow¬Learning) 

Divine Body: An article in the world (yet not on the earth) should be a heavenly body. Models are sun, earth, moon, stars, etc. 

Star: A heavenly body that is depicted by being hot and colossal, and made of gases is a star. A star normally has its own glow and light. 

Full Moon Night: A night when the moon is evident from the earth as a round trip is known as the Full Moon night, and it happens once every month. 

New Moon Night: The fifteenth night after the Full Moon night, when the moon isn’t recognizable at all in the sky, is known as the New Moon night. 

Sublime body: A social affair of a couple of stars which can when in doubt be seen by an unmistakable model is known as a gathering of stars. A model is Ursa Major

Planets: A divine body which pivots around a particular star all around, and gets all its light from that star, is known as a planet. Earth is a planet. 

Satellites: A heavenly body which turns around a planet in a particular circle is known as a satellite. The moon is a satellite of the Earth. 

Circle: The particular and obvious bended way wherein a planet (or satellite) reliably remains, is known as the hover of that planet (or satellite). 

Sun: The Sun is a star that goes about as the “head” of the close by planetary gathering and around which all planets turn: Note that the sun isn’t at the point of convergence of the circle, rather it looks like in the figure above. 

Inward Planets: The Inner Planets are the planets that hover around the sun between the sun and the space rock belt, that is, are close to the sun. These are: Mercury, Venus, Earth and Mars. 

Outside Planets: The Outer Planets are the planets that circle the sun past the space rock belt, that is, are far away from the sun. These are: Jupiter, Saturn, Uranus and Neptune. 

Geoid: The condition of the earth is known as a geoid. A geoid is round beside the leveling at two places oppositely reverse to each other. 

Shafts: The two places oppositely reverse to each other and which lie on the center about which a round body turns are called posts. 

Space rocks: incalculable little heavenly bodies which move around the sun, and are generally present in a belt between the circles of Mars and Jupiter, are called Asteroids. 

Meteoroid: The small sized rock particles moving around the Sun. 

Cosmic system: A world is a variety of unlimited stars. Most stars have their own families like the close by planetary gathering. The Milky Way is where we live. 

Universe: The Universe is the greatest unit wherein we live. It is a combination of astronomical systems. There is only a solitary Universe and all that exists in this Universe itself.
