Study Notes
Planetary Order and Classification
- The planets are arranged in order from closest to furthest from the Sun: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune.
- Inner planets include Mercury, Venus, Earth, and Mars; they are rocky and also referred to as terrestrial planets.
- Outer planets consist of Jupiter, Saturn, Uranus, and Neptune; they are larger and known as gas giants due to their gaseous composition.
Separation and Atmosphere
- An asteroid belt separates the inner planets from the outer planets.
- Inner planets have atmospheres primarily made of nitrogen and oxygen.
- Outer planets have thicker atmospheres rich in hydrogen, ammonia, helium, and methane.
Temperature and Physical Attributes
- Inner planets are generally warmer due to closer proximity to the Sun.
- Outer planets have rings made of dust and ice, while inner planets do not.
Moons and Phases
- The Moon goes through various phases including New Moon, Waxing Crescent, First Quarter, Waxing Gibbous, Full Moon, Waning Gibbous, Last Quarter, and Waning Crescent.
- Each phase represents different positions of the Moon relative to Earth and the Sun.
Earth's Motion
- Earth's rotation refers to its spinning on its axis, completing one full turn every 24 hours, which creates day and night.
- Earth's revolution is the orbit around the Sun, taking approximately 365 days to complete, which defines a year.
Seasons and Axial Tilt
- Seasons are caused by Earth's axial tilt and the revolution around the Sun, affecting sunlight distribution and weather patterns.
- The equator is the imaginary line through the Earth's center, dividing it into Northern and Southern Hemispheres.
Proximity and Common Characteristics
- Earth, the third planet from the Sun, is closest to Mars and Venus.
- Both Earth and the Moon share common characteristics and are part of the same gravitational system.
