Our Solar System

1. Our Solar System By Chloe Beard

2. The Sun- weight: The sun weighs 1 duodecillion kilograms (two billion billion billion tones).INFO- The Sun has an amazing diameter of 1,390,000 km, It’s CORE temperature is 15 million º C, The Sun is about 4.5 BILLION YEARS old. It will probably continue to exist in its present FORM for about another 5 BILLION YEARS before running out of helium and hydrogen, leaving it to explode.

3. Weight: Earth weighs about 6,000,000,000,000,000,000,000,000 kilograms. INFO- Earth is east of Mars and west of mercury. It is 70% covered in water and the other 30% in land. the earth is 4.7 billions years old according to scientists. Earth's biosphere has significantly altered the atmosphere and other abiotic conditions on the planet, enabling the proliferation of aerobic orgasims as well as the formation of the ozone layer which, together with Earths magnetic field, blocks harmful radiation, permitting life on land.

4. Weight: The mass of Venus is 5.36660262 x 1021 tons. Facts: As the second planet to the Sun in the solar system, it is a closest neighbour to the Earth. Known commonly as Morning or Evening star, Venus appears in the sky just before sun rise or just after sun set. It is brighter than stars and can be seen in broad daylight also. It is called an inferior planet in that it is closer to the sun than the Earth. The planet is named after the roman goddess of love and beauty. Many space missions sent by both USA and USSR have given more details about the planet. Some of the space missions are still in the orbit round the planet. Many interesting features and facts about the planet have been revealed by the studies made out of the different missions. This is an attempt to see the overall view of the researches made so far.

5. Weight: Mars weighs: 6.4185×1023 kg Facts: Mars has a very thin atmosphere, mostly carbon dioxide, but dust storms can cover the whole planet for months at a time. About every two years the Earth and Mars come close together. The planet has two moons, Diemos and Phobos. Mars, the fourth planet from the Sun, is commonly referred to as the Red Planet due to its reddish appearance from Earth. The planet is named after the Roman God of War, Mars. It is the seventh largest planet in our solar system. The yellow-orange colour of the Martian surface is due to the presence of oxidized iron in the regolith. The pink-orange colour of the sky is caused by extremely fine red dust that is suspended in the thin atmosphere of Mars.

6. Weight: The weight of Mercury is 3.3022 x 1023kgs Facts: Mercury is a battered and baked planet just larger than Earth's moon. Evidence of heavy bombardment from the chaos of the formation of the solar system is left in the hundreds of craters and resulting lava flows on this small, barren planet. The largest crater is Beethoven at 643 km in diameter and is the largest in the solar system. The largest feature, Caloris Basin, is 1300 km in diameter and was probably caused by an impact from an object larger than 100 km in diameter. Some craters have ice in them even though the planet is so hot because the sun never reaches into the shadows due to the planet's tilt and orbit. With no atmosphere, there is a temperature difference of about 600 degrees between the coldest spots and hottest spots on the planet.

7. Weight: Mercury is about 317.8 Facts: Jupiter takes about 12 years to orbit the sun and rotates in about 10 hours. This short Jupiter "day" is amazing since the planet is roughly 11 Earth diameters wide. The planet had 39 known moons at one and a slight ring of smoke-sized particles and dust. The planet contains 71% of the planetary matter in the solar system and so its huge gravity pulls every object toward it. In fact, most of its moons were captured rather than forming with Jupiter. Scientists watched in awe as comet Shoemaker-Levy 9 broke up and smashed into Jupiter making explosions the size of the Earth.

8. Weight: 86, 492, 000, 000, 000, 000, 000, 000, 000 Facts: Uranus is much smaller than Jupiter and Saturn, but with a diameter of 51,118 km, it is still over four times that of Earths. It would take 15 of our planet to equal the mass of Uranus. Uranus is the seventh planet from the Sun, and the third-largest and fourth most massive planet in the Solar System It is named after the ancient Greek deity of the sky Uranus, the father of Kronos (Saturn) and grandfather of Zeus (Jupiter). Though it is visible to the naked eye like the five classical planets, it was never recognized as a planet by ancient observers because of its dimness and slow orbit. Sir William Herschel announced its discovery on March 13, 1781, expanding the known boundaries of the solar system for the first time in modern history. This was also the first discovery of a planet made using telescope.

9. Weight: Neptune is about 17 earths. Facts: Neptune is the eighth and outermost-known planet from the Sun in the Solar System. Named for the Roman god of the sea, it is the fourth-largest planet by diameter and the third-largest by mass. Neptune is 17 times the mass of Earth and is slightly more massive than its near-twin Uranus, which is 15 Earth masses and not as dense. On average, Neptune orbits the Sun at a distance of 30.1 AU, approximately 30 times the Earth-Sun distance. Its astronomical symbol , a stylized version of the God Neptune's Trident Discovered on September 23, 1846,[1] Neptune was the first planet found by mathematical prediction rather than by empiricalobservation. Unexpected changes in the orbit of Uranus led astronomers to deduce that its orbit was subject to gravitational perturbation.

10. Weight: The mass: 5.6846×1026 KG 95.152 Earths Facts: Saturn is the sixth planet from the Sun and the second largest planet in the Solar System, after Jupiter. Saturn, along with Jupiter, Uranus and Neptune . The planet Saturn is composed of hydrogen, with small proportions of helium and trace elements. The interior consists of a small core of rock and ice, surrounded by a thick layer of metallic hydrogen and a gaseous outer layer. The outer atmosphere is generally bland in appearance, although long-lived features can appear. Wind speeds on Saturn can reach 1,800 km/h, significantly faster than those on Jupiter. Saturn has a planetary magnetic field intermediate in strength between that of Earth and the more powerful field around Jupiter.
