The galaxy that Earth is in is called the a. Big Dipper b. universe c. milky way d. planetary zone c. milky way 7. From what materials did the solar system form? a. Dust and ice b. gas and dust c. magama and gas d. heat and light b. gas and dust 13. Earth’s only natural satellite is? a. The sun b. The solar system c. earth d. the moon d. the moon 16. The planets and stars we see in the night sky all look like tiny points of light. However, the stars are a. much farther from the Earth than the planets b. much closer to Earth than the planets c. just outside our solar system, whereas planets are inside d. moving in and out of the solar system over time a. much farther from the Earth than the planets Our favorite Solar System A solar system is a star and everything that orbits the star Our sun is not the only star with planets: 146 planetary systems Upsilon Andromeda- very similar to ours 3 planets PSR B1620-26- solar system with two stars 1 planet systems .are small in space terms so they are measured using astronomical units Solar 1 AU = the distance from the Earth to the Sun Examples of using AU Everything in the solar system is much smaller than the sun The first 4 planets Terrestrial planets Terrestrial planets are small compared to gas planets Terrestrial planets are made of rock Moons Planet Mercury Number of moons 0 Names Venus 0 Earth 1 moon Mars 2 Phobos, Deimos Outer planets Sometimes called gas giants Rings Terrestrial planets have no rings Though Saturn is famous for its rings all gas planets have them. Neptune Uranus Moons Planet Jupiter Number of Moons 62 Names Io, Europa, Ganymede, Callisto, Amalthea, Himalia, Elara, Pasiphae, Sinope, Lysithea, Carme, Ananke, Leda, Metis, Adrastea, Thebe, Callirrhoe, Themisto, Kalyke, Iocaste, Erinome, Harpalyke, Isonoe, Praxidike, Megaclite, Taygete, Chaldene, Autonoe, Thyone, Hermippe, Eurydome, Sponde, Pasithee, Euanthe, Kale, Orthosie, Euporie, Aitne, plus others yet to receive names 33 Titan, Rhea, Iapetus, Dione, Tethys, Enceladus, Mimas, Hyperion, Prometheus, Pandora, Phoebe, Janus, Epimetheus, Helene, Telesto, Calypso, Atlas, Pan, Ymir, Paaliaq, Siarnaq, Tarvos, Kiviuq, Ijiraq, Thrym, Skadi, Mundilfari, Erriapo, Albiorix, Suttung, plus others yet treceive names Uranus 27 Cordelia, Ophelia, Bianca, Cressida, Desdemona, Juliet, Portia, Rosalind, Belinda, Puck, Miranda, Ariel, Umbriel, Titania, Oberon, Caliban, Sycorax, Prospero, Setebos, Stephano, Trinculo, plus others yet to receive names Neptune 13 Triton, Nereid, Naiad, Thalassa, Despina, Galatea, Larissa, Proteus, plus others to receive names Saturn Asteroids Asteroids are giant rocks orbiting the sun They range in size from about the size of a classroom to the largest which is 580 miles long Asteroids Most asteroids are in the Asteroid belt between Mars and Jupiter Comets •Comets are made of ice, rock and dust •Comets have very elliptical orbits around the sun Comets Comets have a tail when they are close to the sun because of the melting ice Main points Solar systems are a star and what orbits around it Solar systems are measured using A.U. In our solar system we have: the sun gas planets terrestrial planets asteroids comets
