3. How are meteorites different from asteroids?
4.Name and describe the inner planets. Name and describe the outer planets.
6. How does the sun generate or create energy?
9. What is a meteorite? What size are most meteorites?
10. How do the Sun and the Earth compare in size?
1.How are asteroids and planets similar?
Planets are affected by gravity. They are round, orbit around the sun, and may contain rings or additional moons. Planets can have solid, rocky, icy, gaseous, etc. surfaces.
Asteroids also orbit around the sun. They have solid, rocky, and irregular bodies. Asteroids do not have atmospheres, but some may contain companion moons.

2.Why is Venus often referred to as Earth's sister planet?
Venus is is only slightly smaller than Earth.
Both planets have very few craters which means they have a young surface.
The densities and chemical compositions of these planets are similar to.
Meteoroid- is a small rock or particle of debris in our solar system. Size- usually 10 meters in diameter.

Asteroids- are small solar system bodies that orbit the Sun.Made of rock and metal,and sometimes organic compounds. Asteroids are similar to comets but do not have a tail.

Mercury, Venus, Earth and Mars are the Inner planets. These are small and are made of mostly rock.
Jupiter, Saturn, Uranus, Neptune, and Pluto (Dwarf Planet.) are outer planets. These planets are mostly huge and may have many moons.
Pluto is the exception which is small and rocky.

5. What mnemonic device can help you remember the order of the planets.
• My Very Excellent Mother Just Sent Us Nine Pizzas.

• My Very Easy Method Just Simplifies Us Naming Planets.

In the Sun’s core nuclear fusion reacts and can convert hydrogen to helium. This will generate energy.
7. What is the nickname for a comet, and why?
Dirty snowballs, or icy mud-balls. They are a mixture of ices (both water and frozen gases) and dust. These act as good samples of the early history of the solar system.
8. What are asteroids made of? What are the three types?
Scientists suspect that asteroids are made of pieces of planets that may have broken apart. There are 3 types of asteroids:

• M-Type-contains nickel and iron, are very rare
• S-Type- contains nickel, magnesium, and iron
• C-Type- the most common, has a similar composition to that of the sun

A meteorite is made of chunks of rock and metal from asteroids and other planetary bodies that survive their journey through the atmosphere. Most meteorites found on Earth are pebble size but some can be larger than a building.
The Sun’s diameter is about 100 times that of the Earth. Therefore, you would have to line up 100 Earth’s from end to end to stretch across the face of the sun.
Bonus: In what year was Pluto declared a dwarf planet?
