Vulcanoid Belt
• A belt of rocky objects between the sun and Mercury.
• We do not know with certainty that it exists because it is so close to the sun that glare would make small objects difficult to observe.
![Page 5: The Solar System Read the inner planet WS. Inner Planets WS 1. Mercury 2. Venus 3. Earth 4. Mars 5. all 6.Earth 7. Venus 8. Mars 9.Earth. Mars 10. Venus](https://reader036.vdocument.in/reader036/viewer/2022062518/56649de85503460f94ae1ccb/html5/thumbnails/5.jpg)
Planets
• 4 major criteria are required to be called a planet:
– a large body that shines by reflecting sunlight
– revolves in a stable orbit around the sun
– large enough that its own gravity pulls it into a round shape
– Must be dominant enough to clear the area around it
![Page 6: The Solar System Read the inner planet WS. Inner Planets WS 1. Mercury 2. Venus 3. Earth 4. Mars 5. all 6.Earth 7. Venus 8. Mars 9.Earth. Mars 10. Venus](https://reader036.vdocument.in/reader036/viewer/2022062518/56649de85503460f94ae1ccb/html5/thumbnails/6.jpg)
Terms to know!• AU: distance from the Earth to the sun
• Greenhouse Effect:– Atmosphere traps in heat like a blanket. – Thicker atmosphere = greater GH effect=like a thinker blanket– Stabilizes temperature
• Rotation:– Spinning– Determines a Day
• Revolution -orbit– Revolving around a star– Determines a year
• Satellite– Moons – Any object that orbits a planet!

Inner Planets
• Which ones are the inner planets?– Mercury, Venus, Earth, Mars
• Inner planets are also called terrestrial planets. Why?
![Page 9: The Solar System Read the inner planet WS. Inner Planets WS 1. Mercury 2. Venus 3. Earth 4. Mars 5. all 6.Earth 7. Venus 8. Mars 9.Earth. Mars 10. Venus](https://reader036.vdocument.in/reader036/viewer/2022062518/56649de85503460f94ae1ccb/html5/thumbnails/9.jpg)
Inner Planets
• Which ones are the inner planets?– Mercury, Venus, Earth, Mars
• Inner planets are also called terrestrial planets. Why?– They are made mainly of rock and iron-nickel
compounds
Generally smaller in size
![Page 10: The Solar System Read the inner planet WS. Inner Planets WS 1. Mercury 2. Venus 3. Earth 4. Mars 5. all 6.Earth 7. Venus 8. Mars 9.Earth. Mars 10. Venus](https://reader036.vdocument.in/reader036/viewer/2022062518/56649de85503460f94ae1ccb/html5/thumbnails/10.jpg)
Only 2 of the inner planets are inferior.What are the 2 inferior planets?
• Inferior planets – – Most are between Sun and Earth – If closer to the sun, it shows phases like the moon!
![Page 11: The Solar System Read the inner planet WS. Inner Planets WS 1. Mercury 2. Venus 3. Earth 4. Mars 5. all 6.Earth 7. Venus 8. Mars 9.Earth. Mars 10. Venus](https://reader036.vdocument.in/reader036/viewer/2022062518/56649de85503460f94ae1ccb/html5/thumbnails/11.jpg)
Superior Planets
• Superior planets – – further from the Sun than Earth– always appear full (no phases like the moon)– What are the superior planets?
• Mars, Jupiter, Saturn , Uranus & Neptune
Inferior
PHASES
Superior – Always Full
