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

1 AU = the distance from the Earth to the Sun . Solar systems are small in space terms so they are measured using astronomical units 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 Number of moons Names Mercury Venus Earth 1 moon Mars 2 Venus 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 Names Number of Moons Jupiter 62 Saturn 33 Uranus 27 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 Saturn 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

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
