The Planets

  1. 1. Facts about… Slide Number Mercury 3 Venus 4 Earth 5 Mars 6 Jupiter 7 Saturn 8 Uranus 9 Neptune 10 Pluto 11 The Sun 12
  2. 2. ☿ MERCURY ☿ • First planet from the Sun • Has the most eccentric orbit of all planets – 0.21 • Takes 87.969 earth days to complete an orbit. • Like the Moon and Venus, it exhibits phases as seen from Earth. Technically, it is brightest as seen from Earth when it’s at full phase.
  3. 3. ♀ VENUS ♀ • Second planet from the Sun • Orbits the Sun every 224.7 Earth days. • After the Moon, it is the brightest natural object in the night sky • Sometimes called, “Earth’s sister planet” because of their similar size, gravity, and bulk composition • Hottest planet in the Solar System
  4. 4. ♁ EARTH ♁ • Third planet from the sun • The densest and fifth-largest of the eight planets of the System • Largest of the solar system’s four terrestrial planets • The only planet suitable for life… • Unlike the other terrestrial planets, it has a distinct outer and inner core. • Moon is the largest moon in the solar system
  5. 5. ♂ MARS ♂ • Fourth planet from the sun • Second smallest planet in the solar system, after Mercury • “Red Planet” – because the iron prevalent on its surface gives it a reddish appearance • Two known moons – Phobos and Deimos • Best-known planet in culture
  6. 6. ♃ JUPITER ♃ • Fifth planet from the Sun • Largest planet in the solar system • Gas Giant – Primarily composed of hydrogen with ¼ of mass being helium. • Has the Great Red Spot (giant storm) • Has four large moons and at least 63 more Aurora on Jupiter on the magnetosphere
  7. 7. ♄ SATURN ♄ • Sixth planet from the Sun • Second largest planet in the solar system • Best-known for its visible rings • Titan, its largest and the solar system’s second largest moon, is the only moon to retain a substantial atmosphere • The only planet of the solar system that is less dense than water
  8. 8. ♅ URANUS ♅ • Seventh planet from the Sun • Third-largest planetary radius and fourth-largest planetary mass in the system • Placed in the category, “ice giants,” with Neptune because they are of differently composed of ice and rock. • Has a ring system, magnetosphere and numerous moons. • Axis rotation is tilted sideways • Never recognized as a planet by ancient observers because of its dimness and slow orbit
  9. 9. ♆ NEPTUNE ♆ • Eighth planet from the sun in the solar system. • Fourth-largest planet by diameter and third-largest by mass. • Among the gaseous planets in the solar system, it is the most dense. • 17 times the mass of Earth and slightly more massive than its near-twin Uranus • The first planet found by mathematical prediction rather than by empirical observation.
  10. 10. ♇ PLUTO ♇ • Tenth planet from the Sun • The largest object in the Kuiper belt • Second most massive known dwarf planet • It was originally classified as the ninth planet from the Sun. • In 2006, the definition of being a planet excluded it from its status as a “planet”, changing it to a “dwarf planet.” • Five known moons (Nix, Hydra, Kerberos, and Styx), and Charon (the largest)
  11. 11. THE SUN • The star at the center of the Solar System • Consists of hot plasma interwoven with magnetic fields. • About ¾ of its mass consists of hydrogen, while the rest is mostly helium. • Mean distance of the Sun from the Earth is approximately 1 astronomical unit.
