18. Astronomy
Measuring Distances in space
a) 1 Light year- traveling at the speed of light for one year (300,000,000 m/s) or (187,500 miles/s)
b) Astronomical unit-the average distance between the Earth and the Sun

19. Stars generate their own light by nuclear fusion
All stars emit gamma rays, x-rays, infrared, visible light, Ultraviolet and radio waves
Blue stars are hotter than red stars
The moon and planets shine by reflected light

20. Comet- small body of ice, rock and cosmic dust located at the edge of the solar system
Asteroid - small rocky bodies in orbit around the sun- They are mostly located in the asteroid belt between Mars and Jupiter
Meteoroid- similar to an asteroid but smaller orbiting the sun
Galaxy- clusters of billions of stars
Our sun is a star in the Milky Way galaxy

21. Inner Planets called Rocky planets or terrestrial planets Mercury
Standard: 4 Astronomy 5
121
EQ: What is common between the inner planets?
Inner Planets
Inner Planets called Rocky planets or terrestrial planets
Mercury
Smallest Planet and closest to the sun
Mercury moves very slowly
No Moons
Rotation-spin on its axis 59 days
Revolution- orbit around the
Sun - year is equal to 88 Earth
days 26

22. -Virtually the same size, mass and Density as Earth
2. Venus
-Virtually the same size, mass and Density as Earth
-Sun rises in the west and sets in the East because it rotates opposite to Earth
-One day on Venus is about as long as a year on Earth
-Hottest surface because the atmosphere is a thick cloud of CO2 (464° C).
-Rains sulfuric acid
-No oceans, Active volcanoes
-No Moons
-Typically the brightest object in the sky. 27

23. Just the right distance from the sun
Standard: 4 Astronomy
3. Earth
Just the right distance from the sun
Temperatures are right to not completely freeze or boil away the water 28

24. Thin atmosphere and further from the sun so it is a cold planet
4. Mars
Last Inner planet
Thin atmosphere and further from the sun so it is a cold planet
Water is in solid form-ice
Largest volcanoes
2 moons
Rotation is 24 hours and 37 minutes – Similar to the Earth.
Revolution takes 1 year, 322 days 29
