#1 •The colors of the rainbow •Red, Orange, Yellow, Green, Blue, Indigo, Violet •ROYGBIV #2 •The continuous spectrum. #3 • The chemical elements and gases that are present. • Temperature. • Pressure. • How magnetic the star is. • Which way the star might be moving. #4 ►A group of stars that appears to form a pattern in the sky. ►Constellations are imaginary. #5 ►The ►The rotation of the Earth. Earth revolving around the sun. #6 ►No because stars are moving “shifting,” or moving closer or further away from one another. #7 Density Mass Color Temperature Luminosity Distance from Earth #8 Apparent- How bright a star looks from Earth. Absolute- How bright a star actually is. Our sun. Sirius Rigel #9 Large. #10 Nebula Supernova #11 Milky Spiral Way #12 110 Our times the Earth’s diameter. sun could hold more than 1 million Earths. #13 Hydrogen and Helium. #14 Gravity. #15 through #21 • • • • • • • B A and B B and C A A, B, and C A A #22 through #24 •C •C •B #25 through #31 A D B C E B A #32 Reached escape velocity. Take pictures of safe landing sites. Able to soft land on the moon. First spacecraft to carry an astronauts. Designed for two astronauts. Putting a person on the moon. Designed to be reused. #33 The moon’s diameter is 3,476 km, or one fourth of the Earth’s diameter. #34 The moon’s gravity is one sixth Earth’s. It is very easy to launch off of the moon. #35 20 pounds #36 Highlands Maria #37 Penumbra- a partial shadow Umbra- total shadow #38 Lunar Eclipse #39 Moon Earth Sun #40 Earth Moon Sun #41 6 hours and 12.5 minutes #42 No low or high tides. Same tide. No waves. The sun has less of an effect. #43 •23.5 degrees #44 •Rotation- the Earth spinning around once every 24 hours •Revolution- the Earth going around the sun #45 •Winds move differently in the Northern and Southern Hemispheres. #46 •We see different stars or constellations in the sky throughout a year.
