What is Solar System The Solar System is made up of all the planets that orbit our Sun. In addition to planets, the Solar System also consists of moons, comets, asteroids, minor planets, and dust and gas. Everything in the Solar System orbits or revolves around the Sun. The Solar System is entirely dependent on Sun & the only one which is self- luminous i.e which has its own light. The rest of the planets reflect the light received from the sun.

Sun –Star of the Solar System It’s the heaviest object in our solar system. It 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

Sun –Star of the Solar System It is the source of all energy for life on Earth. About three quarters of the Sun's mass consists of hydrogen, while the rest is mostly helium. On the Sun’s surface ,there are dark patches known as sunspots. These are patches of gas that look dark since they are cooler than their surroundings. www.makemegenius.com Free Science Videos for Kids

www.makemegenius.com Free Science Videos for Kids Planets The word planet comes from the Greek word meaning wanderer. 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, and is now known as a dwarf planet. All planets fall in 2 groups Inner Planets: Mercury , Venus, Earth and Mars are called inner planets. Outer Planets: These are Jupiter , Saturn, Uranus, Neptune www.makemegenius.com Free Science Videos for Kids

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

Mercury –The Innermost Planet  It is also the smallest, and its orbit is the most not fully circular. It does not have any satellites. There is no water or atmosphere It can be seen with naked eyes. It orbits the Sun once in about 88 Earth days  There are no seasons on its surface www.makemegenius.com Free Science Videos for Kids

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

Venus –The Veiled Planet It orbits the Sun once 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. www.makemegenius.com Free Science Videos for Kids

www.makemegenius.com Free Science Videos for Kids 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 earth’s atmosphere scatters the light & creates a blue effect,so it is also called Blue Planet.. Only planet having life . www.makemegenius.com Free Science Videos for Kids

www.makemegenius.com Free Science Videos for Kids Earth –The Blue Planet It orbits the Sun once in about 365 Earth days. It rotates about its own tilted 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. Earth has one satellite that we call Moon. www.makemegenius.com Free Science Videos for Kids

www.makemegenius.com Free Science Videos for Kids Mars –The Red Planet It is named after the Roman god of war. It is often described as the "Red Planet", as the iron oxide (rust) prevalent on its surface gives it a reddish appearance. www.makemegenius.com Free Science Videos for Kids

www.makemegenius.com Free Science Videos for Kids Mars –The Red Planet Mars has approximately half the diameter of Earth It 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  oxygen and water Mars also has the largest dust storms in the Solar System. www.makemegenius.com Free Science Videos for Kids

Jupiter –The Giant Planet It is named after the Roman god Jupiter (ruler of Roman gods) Jupiter is the largest  planet within the Solar System It has a great “Red Spot”, which is a rotating storm system inside the planet. www.makemegenius.com Free Science Videos for Kids

Jupiter –The Giant Planet Jupiter rotates faster than any other planet. It completes one rotation in 10 Earth hours Jupiter has a faint ring 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 satellites . www.makemegenius.com Free Science Videos for Kids

Saturn –The Jewel Planet Saturn is the sixth planet from the Sun and the second largest planet in the Solar System, after Jupiter. It is named after the Roman god Saturn Saturn is classified as a gas giant planet It 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 particles It 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 29½ years), to finish one revolution around the Sun www.makemegenius.com Free Science Videos for Kids

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

www.makemegenius.com Free Science Videos for Kids Uranus –A planet on its Side It has at least ten thin uniform black rings ,which are made of dust. It has 27 known satellites It 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. www.makemegenius.com Free Science Videos for Kids

Neptune –The Last Giant Most distant gas planet. It is named after the Roman god of the sea . Most windy planet www.makemegenius.com Free Science Videos for Kids

Neptune –The Last Giant Can’t be seen with naked eye It has 8 known satellite  As it is very far from the sun, it completes an orbit on average every 164.79 Earth years. The average distance between Neptune and the Sun is 4.50 billion km. Neptune was the first planet found by mathematical prediction. www.makemegenius.com Free Science Videos for Kids
