What is Solar SystemThe Sun, its planets and all the objects moving around them collectively are called Solar System.The Solar System is entirely dependent on Sun & the only one which is self- luminous i.e which has its own light.Rest of the planets reflect the light received from Sun

Sun www.makemegenius.com Free Science Videos for Kids


Sun Star of the Solar System It s the heaviest among solar systemIt is a ball of hot ,burning gases.It is the nearest star to the earth.The light from the Sun takes appx. 8 minutes to reach Earth.www.makemegenius.com Free Science Videos for Kids


It is the source of all energy for life on Earth.About three quarters of the Sun's mass consists ofhydrogen, while the rest is mostlyhelium.On the Suns surface ,there are dark patches known as sunspots. These are patches of gas that looks dark since they are cooler than their surroundings.

Planetswww.makemegenius.com Free Science Videos for Kids


PlanetsPlanet word comes from Greek ,which means wandering star.Planets are heavenly bodies ,which revolve around the Sun in elliptical orbits.Earlier it was considered there were 9 planets in Solar system but lately one planet called Pluto was de-classified from being a planet.

All planets fall in 2 groupsInner Planets: Mercury , Venus, Mars and Earth are called inner planets.Outer Planets: These are Jupiter , Saturn, Uranus, Neptune



Between Inner & Outer Planets ,there is a ring of small bodies , which are made of rock & metal, these are called Asteroids. They also keep moving around the Sun .This ring is also called Asteroids Belt.www.makemegenius.com Free Science Videos for Kids


Mercury www.makemegenius.com Free Science Videos for Kids


Mercury The Innermost Planet It is named after messenger of the Roman godsIt is the closest planet to the SunLarge variations in day(400 degree C) & night (-180 degree C) time temperatures.www.makemegenius.com Free Science Videos for Kids


It is also the smallest, and its orbit is the mostnot fully circular.It does not have any satellite.There is no water or atmosphereIt can be seen with naked eyes.ItorbitstheSunonce in about 88 Earth daysThere are no seasons on its surfaceMercury The Innermost Planet www.makemegenius.com Free Science Videos for Kids


Venus



Venus The Veiled Planet Venus is surrounded by thick cloud cover ,that is why it is called Veiled Planet.It is brightest & hottest planet.It is named after Roman goddess of love & beauty .www.makemegenius.com Free Science Videos for Kids


ItorbitstheSunonce in about 225 Earth days.Venus reaches its maximum brightness shortly before sunrise or shortly after sunset, so it is also known as the Morning Star or Evening Star.Venus is also known as Sister or Twin planet to earth because of its similar size & mass to earth.

Earth



Earth The Blue Planet It is also known as watery planet, because 70% of its surface is covered by water.It reflects about 1/3rd of sunlight it receives .The earths atmosphere scatters the light & creates a blue effectn,so it is also called Blue Planet..Only planet having life .www.makemegenius.com Free Science Videos for Kids


ItorbitstheSunonce in about 365 Earth days.It rotates about its own axis, thus creating day & night. It takes 24 hours to do that.It revolves around sun, due to its tilt ,seasons are created.Due to gravity, the layer of gases remain attached to it (which is known as atmosphere), it prevents too much heat or UV rays from Sun reaching earth.Moon is the only satellite of the Earth.

MoonNot a Planet but the only satellite of the Earth



Moon The Earths Only Satellite Its diameter of only 1/4th of the Earth It looks bigger to us as it is very close to us.The moon has no atmosphere ,so there is huge difference between day & night temperature. (127 degree C in Day to -173 degree C in Night)www.makemegenius.com Free Science Videos for Kids


As there is no atmosphere, there is no weather, no rain, no wind or clouds.Like everything else in Solar System, Moon also does not have its own light . It shines due to Suns light .There is no water on its surface.Moons gravity is 1/6th of Earth, so your weight would be 1/6th of your weight on the earth.Moon The Earths Only Satellite www.makemegenius.com Free Science Videos for Kids


The Moon is the onlycelestial bodyother than Earth on whichhumans have set foot.

Neil Armstrong became the first person to walk on the Moon as the commander of the American missionApollo 11by first setting foot on the Moon on 21 July 1969.

Mars



Mars The Red Planet It is named after theRomangod of war. It is often described as the "Red Planet", as theiron oxideprevalent on its surface gives it areddish appearancewww.makemegenius.com Free Science Videos for Kids


Mars has approximately half thediameterof EarthIt has two satellites.The gravity of Mars is half of the earth .The atmosphere of Mars consists of about 95%carbon dioxide, 3%nitrogen,1.6%argon and contains some oxygenand waterMars also has the largest dust stormsin the Solar System

Jupiter



Jupiter The Giant Planet It is named after theRomangod Jupiter (ruler of Roman gods) Jupiteris thelargestplanet within theSolar SystemIt has a great Red Spot ,it is rotating storm system inside the planet.



Jupiter rotates faster than any other planet.It completes one rotation in 10 hoursJupiter has a faintring system, these rings appear to be made of dust.This is also a windy planet as the fast rotation causes high winds.It has 16 planets.

Saturn www.makemegenius.com Free Science Videos for Kids


Saturn The Jewel Planet Saturnis the sixthplanetfrom theSunand the second largest planet in theSolar System, afterJupiter. It is named after theRomangodSaturnSaturn is classified as agas giantplanetIt is the most beautiful planet in solar system because of its spectacular rings www.makemegenius.com Free Science Videos for Kids


Saturn-The Jewel Planet Saturn rings are made up of ice & ice covered particlesIt has 22 known satellites .It can be seen by naked eye Saturn is 95 times heavier than earth it takes Saturn 10,759 Earth days (or about 29years),to finish one revolution around the Sunwww.makemegenius.com Free Science Videos for Kids


Uranus



Uranus A planet on its Uranus appears to lie on its side.It is named after theRomangodof the sky.The only planet which rotates on its axis from east to west.Side www.makemegenius.com Free Science Videos for Kids


It has at least ten thin uniform black rings ,which are made of dust.It has 27 known satellitesIt is a very cold planet ,it receives 370 times less sunlight than Earth as it is far away from sun as compared to Earth.Its core is very rocky.
