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

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

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

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

-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

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

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
