  1. Planetary System Vocab

  2. The planets spin on an axis

  3. Revolution The Earth’s orbit or movement around the Sun

  4. Axis • Imaginary line running from north to south

  5. Angle of Insolation The angle at which the Sun’s light hits the Earth

  6. Spring Tide • The highest high tides and the lowest low tides that occur during new & full moons

  7. Neap Tides • The lowest high tides & • highest low tides that occur • during quarter moons

  8. Waxing When the moon gains light

  9. Waning • When the moon loses light

  10. Gibbous • More than 50% of the moon is illuminated by the sun from earths view

  11. Crescent • Less than 50% of the moon is illuminated by the sun from Earth’s view

  12. Quarter • Exactly 50% of the Moon is illuminated by the Sun from Earth’s view

  13. Full moon • 100% of the Moon is illuminated by the Sun from Earth’s view

  14. New m n • 0% of the Moon is illuminated by the Sun from Earth’s view

  15. Lunar eclipse • When the Moon passes into the Earth’s shadow

  16. Solar eclipse • When the Earth passes into the Moon’s shadow

  17. Galactic address • The place in the universe which we live in, starting with the universe and working towards our house address

  18. Gravity factor • The amount which gravity affects the mass of an object

  19. Weight • The measurement of gravity’s effect on mass

  20. How much would I weight on... • Earth: 105 • The Moon: 17.4 • The Sun: 2842.5 • Mercury: 39.6 • Venus: 95.2 • Mars: 39.5 • Jupiter: 248.2 • Saturn: 111.7 • Uranus: 93.3 • Neptune: 118.1 • Pluto: 7
