Transcript of The Solar System

By: Cat, Deni, & Cindy The Solar System Venus Earth Jupiter Mars Saturn Uranus Closest to the Sun About the size of Earth 5th largest planet Huge Magnetic Field Largest moon is sightly bigger than Mercury has rings The Planets Somewhat bigger than Earth's moon Has little atmosphere to stop collisions Mercury Dwarf Planets Quick Overview Our sun, planets, moons, asteroids, meteorites, comets, and everything else make up our Solar System elliptical shape The Big Bang Theory (or egg shaped) The Solar System is still growing, never stopping it's expansion. It also never stops rotating in a counter-clockwise direction. asteroid belt 88 Mercury Days to orbit the sun (175 Earth Days) Temperatures can reach 800 *F Atmosphere traps heat, causing temperatures to reach over 880 *F Takes 243 Earth days to orbit the Sun Atmosphere is made of carbon dioxide clouds with sulfuric acid droplets Surface is 70% water 78% Nitrogen 21% Oxygen 1% Other Atmosphere Cold Desert planet Although it cannot sustain life, seasons, polar ice caps, volcanoes, weather, and canyons Thin atmosphere, no magnetic field Two moons Over 50 moons The Great Red Spot can contain more than 100 Earths!! are created by strong winds in the upper atmosphere Jupiter's Stripes (Dark Belts & Light Zones) Volume is 755 times greater than Earth Mostly Helium and Hydrogen Scientists believed that the universe began 14 billion years ago Wind speeds range from 500 m per second. Because of the high speed mixed with heat rising from planets interior,. this causes the yellow bands you see Neptune has rings Only planet that rotates on it's side Made of methane, helium, & hydrogen (methane gives it it's blue color) Takes 84 Earth years to orbit Sun One of two Ice Giants Has 27 moons Takes around 165 Earth years to orbit the Sun Winds are 3 times stronger than Jupiter's and 9 times stronger than Earths. Is made from methane, along with some unknown components Great Storm spot that is large enough to contain Earth has rings dark, cold, supersonic winds A planet could be considered a celestial body that orbits the Sun in our Solar System. A dwarf planet is considered a planetary mass-object that lacks the ability to sweep up any object near its orbit. In other words, a dwarf planet is a body that is only big enough to hold itself together, and orbit other things. Size Comparison Sun Chief Component, what everything orbits around in the Solar System (perfect distance for life) Classified as a G2 Yellow Dwarf
Made of mostly Helium and Hydrogen
Is 99.8% of the Solar System's Mass
Middle Aged (about 4.5 billion years old)
150 million km away from Earth Our size compared to the Sun (the Sun is a million times bigger) Has used up 30-55% of its energy Chunks of rock/ice that are not part of a planet COMETS ASTEROIDS METEORITES (frozen gases, dust, and rock in the nucleus) "cosmic snowballs" The closer it gets to the sun, it heats & melts the gases and develops an atmosphere, creating its "tail" can be the size of a small town Chunks of debris & rock When it falls through the atmosphere of Earth it is called a shooting star, when it hits the ground it is then a meteorite 1,000-10,000 hit Earth each day airless worlds that orbit the Sun mostly gathered around the Asteroid belt Double asteroids (2 that orbit each other) 150+ asteroids have a moon Stars has rings Bright sphere containing plasma held together by gravity More than a trillion in the universe (turning hydrogen into helium in its core) Stars shine because of thermonuclear fusion Red dwarfs take up about 85% in the S.S. x10 of the Sun: 100 Million Years Our Sun's Mass: 13 billion years 1/10 of our Sun: 100 billion years or longer located between the orbits of Mars and Jupiter some minor/dwarf planets mass has been greatly reduced over time Began as very hot, small & dense with absolutely nothing (no atoms, structure...) Suddenly started to expand quickly (therefore gave the name big bang) resulting in the formation of atoms which then lead to the creation of stars, and galaxies. Satellites There are many satellites that currently orbit earth. Active ones track the weather, giving us communication, and take photos. Man made machines sent to space to orbit planets to collect information But, there are millions of objects (debris) orbiting right now (AKA Space Junk)! Inner Planets: Smaller & closest to Sun Rocky Most have atmospheres Few or no moons No rings Outer Planets None have solid surfaces All are Gas Giants Planets beyond asteroid belt Uranus & Neptune are Ice Giants (Jupiter, Saturn, Uranus, Neptune) (Mercury, Venus, Earth, Mars) Planets Before Asteroid Belt (Not the show) Ringed
