The Solar System means the family of the sun. It consists mainly of the Sun & the nine planets – four rocky inner planets near the Sun, including the Earth & the 5 planets away from the Sun. The planet revolves around the Sun in the fixed path. Beside the planet, there satellites or moon & huge chunks of rocks, no comets, asteroids & meteoroids , float in the interplanetary orbits. The largest planet of the Solar System is Jupiter & the smaller is Pluto.
The sun is a huge ball of gasses which generates great heat & light. The sun is actually a small star among the million of a galaxy. Though a star, it is 1 09 times bigger than the Earth &740 times heavier than the mass of all the planets put together. The Sun is mainly consists of two gasses “HELIUM& HYDROGEN
The planets are large bodies, made of gasses, metals or rocks that orbits around a star and does not emits visible light of its own but instead shines by reflected light. In the solar system, there are nine planets =Mercury,
1. 2. 3. 4. 5. 6. 7. 8.
Mercury = Messenger of Gods Venus = Goddess of love Mars = God of war Jupiter = King of the Gods Saturn = Father of Jupiter Uranus = God of the Heaven Neptune = God of sea Pluto = God of the underworld
Mercury is one of the planets in the solar system. Mercury orbits closest to the Sun of all the planets, at an average distance of approximately 58 million km The planet’s diameter is 4,879 km and its volume and mass are about oneeighteenth that of Earth. The force of gravity on the planet's surface is about one-third of that on Earth's surface or about twice the surface gravity on the Moon.
Venus is one of the planets in the solar system, the second in distance from the Sun. Except for the Sun and the Moon, Venus is the brightest object in the sky. In ancient times the evening star was called Hesperus and the morning star Phosphorus or Lucifer. Because of the distances of the orbits of Venus and Earth from the Sun, Venus is never visible more than three hours before sunrise or three hours after sunset.
Earth (planet), one of nine planets in the solar system, the only planet known to harbor life, and the “home” of human beings. From space Earth resembles a big blue marble with swirling white clouds floating above blue oceans. About 71 percent of Earth’s surface is covered by water, which is essential to life. The rest is land, mostly in the form of continents that rise above the oceans.
The emergence of the theory that the solar system coagulated from a vast cloud of dust has led to a new inquiry into the chemical history of our planet
Mars is one of the planets in the solar system, it is the fourth planet from the Sun and orbits the Sun at an average distance of about 228 million km. Mars is named for the Roman god of war and is sometimes called the red planet because it appears fiery red in Earth’s night sky.
Scientists believe these channels in a crater wall on Mars were formed by water. The sharpness of the features and the lack of small impact craters covering them imply that the channels formed relatively recently in the history of the planet. Liquid water, therefore, may still exist below the surface of Mars.
Jupiter is the fifth planet from the Sun and the largest planet in the solar system. The fourth brightest object in Earth’s sky, after the Sun, the Moon, and Venus, Jupiter is more than three times brighter than Sirius, the brightest star. Due to its prominence in the sky, the Romans named the planet for their chief god, Jupiter.
Jupiter’s atmosphere is composed mostly of hydrogen and helium with lesser amounts of minor gases. White clouds of frozen ammonia crystals and other colored clouds, including the Great Red Spot, swirl around in atmospheric currents as the planet rotates. The Great Red Spot was photographed by Voyager 1 in 1979.
Saturn is the sixth planet in order of distance from the Sun, and the second largest in the solar system. Saturn's most distinctive feature is its ring system, which was first seen by Galileo. The Dutch astronomer Christiaan Huygens was the first to describe the rings correctly. The rings are named in order of their discovery, and from the planet outward they are known as the D, C, B, A, F, G, and E rings. These rings are now known to comprise more than 100,000 individual ringlets, each of which circles the planet.
The visible rings stretch out to a distance of 136,200 km from Saturn's center. They are thought to consist of aggregates of rock, frozen gases, and water ice ranging in size from less than 0.0005 cm in diameter to about 10 m in diameter—from dust to boulder size. An instrument aboard Voyager 2 counted more than 100,000 ringlets in the Saturnian system. The apparent separation between the A and B rings is called Cassini's division. Oyager's television showed five new faint rings within Cassini's division. The wide B and C rings appear to consist of hundreds of ringlets, some slightly elliptical. The gravitational interaction between rings and satellites, which causes these density waves, is still not completely understood. The B ring appears bright when viewed from the side illuminated by the Sun, but dark on the other side because it is dense enough to block most of the sunlight. Voyager images have also revealed radial, rotating spokelike patterns in the B ring.
Uranus is the major planet in the solar system and seventh planet from the Sun. Uranus revolves outside the orbit of Saturn and inside the orbit of Neptune. The average distance from Uranus to the Sun is 2.87 billion km. Uranus has an inner rocky core that is surrounded by a vast ocean of water mixed with rocky material. Uranus has 11 known rings and 27 confirmed moons. The mass of Uranus is 14.5 times greater than the mass of Earth, and its volume is 67 times greater than that of Earth. Because of its great size and mass, scientists classify Uranus as one of the giant or Jovian planets—along with Jupiter, Saturn, and Neptune.
“Uranus’s ocean is extremely hot (about 6650°C/about 12,000°F).”
Neptune is the major planet in the solar system, eighth planet from the Sun and fourth largest in diameter. Neptune maintains an almost constant distance, about 4.5 billion km from the Sun.
Pluto is the ninth planet from the Sun and outermost known planet of the solar system. Pluto revolves about the Sun once in 247.7 Earth years at an average distance of 5.91 billion km . Pluto is about 2,360 km in diameter, about twothirds the size of Earth's moon. Discovered in 1930, Pluto is the most recent planet in the solar system to be detected.
According to 2006, Pluto is not considered as the part of Solar Family
