Solar system Presentation Transcript

  • 1. Mercury means:In astronomy mythology, Mercury was the Roman version of the Greek godHermes. He was the messenger for the other gods, and for this reasonMercury is often depicted in pictures with winged sandals. In addition todelivering messages, he was also the protector of travelers and merchants.
  • 2. Venus (0.7 AU from the Sun) is close in size to Earth (0.815 Earth masses), and, likeEarth, has a thick silicate mantle around an iron core, a substantial atmosphere andevidence of internal geological activity. However, it is much drier than Earth and itsatmosphere is ninety times as dense. Venus has no natural satellites. It is the hottestplanet, with surface temperatures over 400°C, most likely due to the amount ofgreenhouse gases in the atmosphere.[45] No definitive evidence of current geologicalactivity has been detected on Venus, but it has no magnetic field that would preventdepletion of its substantial atmosphere, which suggests that its atmosphere is regularlyreplenished by volcanic eruption.
  • 3. Earth (or the Earth) is the third planet from the Sun, and the densest and fifth-largest of the eight planets in the Solar System. It is also the largest of the SolarSystems four terrestrial planets. It is sometimes referred to as the world, the BluePlanet,[21] or by its Latin name, Terra
  • 4. Mars is the fourth planet from the Sun in the Solar System. Named after the Romangod of war, Mars, it is often described as the "Red Planet" as the iron oxide prevalenton its surface gives it a reddish appearance.[13] Mars is a terrestrial planet with a thinatmosphere, having surface features reminiscent both of the impact craters of theMoonand the volcanoes, valleys, deserts, and polar ice caps of Earth. The rotationalperiodand seasonal cycles of Mars are likewise similar to those of Ear
  • 5. Jupiter is the fifth planet from the Sun and the largest planet within the Solar System.[13] It is a gas giant with mass one-thousandth that of the Sun but is two and a halftimes the mass of all the other planets in our Solar System combined. Jupiter isclassified as a gas giant along with Saturn, Uranus and Neptune. Together, thesefour planets are sometimes referred to as the Jovian or outer planets
  • 6. Saturn is the sixth planet from the Sun and the second largest planet in theSolar System, after Jupiter. Named after the Roman god Saturn, itsastronomical symbol(♄) represents the gods sickle. Saturn is a gas giant with anaverage radius about nine times that of Earth.[12][13] While only one-eighth theaverage density of Earth, with its larger volume Saturn is just over 95 times asmassive as Earth
  • 7. Uranus is the seventh planet from the Sun. It has the third-largest planetary radius andfourth-largest planetary mass in the Solar System. It is named after the ancient Greekdeity of the sky Uranus (Ancient Greek: Οὐρανός), the father of Cronus(Saturn) andgrandfather of Zeus (Jupiter). Though it is visible to the naked eye like the fiveclassical planets, it was never recognized as a planet by ancient observers because ofits dimness and slow orbit.
