Solar System Flashcards - Planets

• Flashcard 1: Planet: Mercury

  • Closest to the Sun
  • Very hot and very cold
  • Smallest planet

• Flashcard 2: Planet: Venus

  • Covered in thick clouds
  • Hottest planet
  • Rotates backwards

• Flashcard 3: Planet: Earth

  • Only planet known to support life
  • The "blue planet"
  • Has liquid water

• Flashcard 4: Planet: Mars

  • Reddish color due to iron oxide
  • Known as the "Red Planet"
  • Possible past life

• Flashcard 5: Planet: Jupiter

  • Largest planet
  • Mostly gas (hydrogen and helium)
  • Great Red Spot (a massive storm)

• Flashcard 6: Planet: Saturn

  • Known for its rings
  • Also largely made of gas
  • Second largest planet

• Flashcard 7: Planet: Uranus

  • Rotates on its side

Solar System Planets - Additional Points

• Inner Planets (Terrestrial): Mercury, Venus, Earth, and Mars. These are rocky planets, relatively small, and closer to the sun.
• Outer Planets (Gas Giants): Jupiter, Saturn, Uranus, and Neptune. Larger in size, predominantly made of gas (hydrogen and helium) and have rings.
• Dwarf Planets: (Not on flashcards, but important to mention). These are celestial bodies similar to planets but do not dominate their region of space. Examples include Pluto, Eris, and Ceres.

Key Concepts

• Orbit: The path of a planet around the Sun. Planets orbit in ellipses, not perfect circles.
• Rotation: The spinning of a planet on its axis. This determines the length of a day on a planet.
• Revolution: The movement of a planet around the sun. This determines the length of a year on a planet.
• Gravity: The force that keeps planets in orbit around the sun.
• Solar System: The Sun and the objects that orbit it, including planets, moons, asteroids, comets, and dust.

Planetary Characteristics - Details

• Orbit Distances: The distance of each planet from the Sun is significantly varied
• Size and Composition: Size and composition of each planet differs.
• Temperature: Varies dramatically depending on distance from the Sun.
• Rotation and Revolution: Rotation and revolution speed is diverse
• Moons: The number of moons orbiting each planet differs from planet to planet.
