1 ASTRONOMY NOTES CHAPTER 3: THE SOLAR SYSTEM LESSON 1: MODELS OF THE SOLAR SYSTEM GEOCENTRIC MODEL = Earth is at the center of the revolving planets & stars 1. Early observers thought Earth was at center of universe a. Early Chinese thought Earth was under a dome of stars b. Early Greeks thought that Earth was inside rotating spheres nested inside each other. è. 2. Ptolemy s Model a. 140 A.D. Ptolemy (Greek) further developed geocentric model. b. Said that Earth was at center of universe, and all the planets & stars orbit our planet. c. Geocentric model accepted for 1500 years!! HELIOCENTRIC MODEL = Earth and other planets revolve around the sun. 1. Copernican Revolution (1543).Given credit for HELIOCENTRIC MODEL even though a Greek first proposed it. a. Nicolaus Copernicus- worked out the arrangement of the known planets and how they move around the sun. CHANGED SCIENCE FOREVER!!... THE SUN IS THE CENTER 2. Brahe- HYBRID MODEL (late 1500s) a. Tycho Brahe- he thought that the earth is at rest in the middle of the universe. The moon obviously goes around the earth and so does the sun and the stars. All the other planets, however, go around the sun.

2 3. Johannes Kepler- Shape of Planets Orbits (1609) was Brahe s assistant. a. Kepler said that the orbit of each planet is an ellipse- (oval shape) b. Sun is slightly offset in the orbits c. Planets closer to sun orbit faster than those further out you are older on Mercury than on Earth 4. Galileo s Evidence (1610) a. Used a telescope to discover 4 moons around Jupiter. Proved that not everything in sky revolves around Earth. Found that Venus goes through series of phases like moon s.. also proved that planets are solid bodies like Earth. 5. Isaac Newton (1687) a. Explained WHY we orbit the Sun & the moons orbit the planets. b. Cuz Sun contains 99.9% of mass of our solar system.. exerts huge gravitational pull. 6. Edwin Hubble (1924) a. Proved that the Milky Way galaxy isn t the only one out there.are other galaxies in the universe. 1. Solar system = consists of the sun, planets, their moons & variety of smaller objects. a. Sun is at center everything orbits around it. LESSON 2: INTRODUCING THE SOLAR SYSTEM

3 b. Force of gravity holds solar system together. c. Distances in Solar System i. Astronomical Unit (AU) = average distance between Earth & Sun = 150 million kilometers ii. Solar system extends more than 100,000 AU from the Sun. WHAT MAKES UP THE SOLAR SYSTEM 1. Our Sun a. About 99.9% of mass of solar system is contained in our sun b. Sun is ordinary mid sized star c. Will last for 5 billion more years 2. Planets a. Planet = Round, orbit the sun & have cleared out region of the solar system along its orbit. b. 8 planets in our solar system 3. Dwarf Planets a. Dwarf planet = object that orbits the sun & has enough gravity to be spherical, but has NOT cleared the area of its orbit. b. 5 dwarf planets in our solar system 4. Natural Satellites (Moons) à Except for Mercury & Venus.. every planet in solar system has at least 1 moon (satellite). 5. Smaller Objects found in our Solar System à Asteroids à Comets A. SOLAR SYSTEM FORMATION! 1. Formed about 4.6 billion years ago a. Gravity pulled cloud s material together started spinning.. temp & pressure got so high that NUCLEAR FUSION started Sun gave off light.

4 b. Away from sun.. planets started to form. c. Gravity pulled rock, ice & gas together formed PLANETESIMALS = small asteroid like bodies that formed the planets i. Inner Planets Low in mass, small & rocky ii. Outer Planets- Gas giants had strong gravity. LESSON 3: THE SUN 1. Sun has an interior and an atmosphere. The interior includes the core, radiation zone & convection zone. 2. Layers of Sun a. The Core = central region, hottest part i. Enormous amount of ii. energy produced Nuclear Fusion= hydrogen atoms join to form helium..needs high temps & pressures b. Radiation Zone = tightly packed gas where energy moves mainly in the form of electromagnetic radiation. i. Energy can take more than 100,000 years to move through it. c. Convection Zone = outermost layer of sun s interior i. Hot gases rise & cool gases sink, forming loops of gas that move energy toward Sun s surface. 3. Sun s Atmosphere a. Photosphere = inner layer of sun s atmosphere i. when you look at image of sun you see the photosphere Sun s surface layer b. Chromosphere= middle layer of sun s atmosphere i. color sphere of the sun c. Corona = outer layer.. looks like white halo around Sun. i. Extends into space for millions of km, see it during solar eclipses ii. Thins into streams of charged particles = Solar Wind * ORDER OF SUN S INTERIOR AND ATMOSPHERE CORE à RADIATION ZONE à CONVECTION ZONE à PHOTOSPHERE àchromosphere à CORONA

5 What Features Can You See On the Sun?? 1. Sunspots = 2. Prominences 3. Solar Flares 4. Solar Wind areas of gas on sun s surface that are cooler than areas around them à Occur in 11 year cycles àwe are currently in a SOLAR MAXIMUM increased solar activity = huge loops of gas that link north & south poles of sunspots = eruptions of gas from the sun into space, happens when loops in sunspots slide & connect together. a. Solar flares can increase solar wind these particle can enter Earth s atmosphere at poles àaurora s (Northern Lights). b. Can cause magnetic storms that disrupt cell phone service, radio/tv transmissions. àsolar MINIMUM is predicted to start possible around Have caused Ice Ages in the past.

6 LESSON 4: INNER PLANETS SMALL DENSE.ROCKY à rocky- have metallic minerals (iron & silicon) è All have some atmosphere EXCEPT Mercury 1. Terrestrial planets = another name for 4 inner planets. MERCURY VENUS EARTH MARS SIZE & Small, solid & rocky COMPOSTION -1 day = 59 Earth days -1 year = 88 Earth days -Earth s twin for size -1 day = 8 Earth months ** rotates & orbits opposite of all the other planets. * Sun rises in West her 3 layers- crust, mantle, core -Sept liquid water on Mars -June ice was discovered at poles -1 day= 25 Earth hours MERCURY VENUS EARTH MARS ATMOSPHERE No atmosphere Dense clouds of CO 2 Drops of sulfuric acid fall from sky N 2, O 2, and other gases Very Thin atmosphere (95% CO 2) Day & Night = 870 F Day = 60 F TEMPS Day= 800 F Night= -280 F ** Greenhouse Planet- Known for Greenhouse Effect= trapping of heat near planets surface by gases Vary from pole to pole Night = -130 F Goes thru seasons

The most studied planet Twin Rover (2003) Mariner 9 Viking 1 & 2 Many others!! LESSON 5: THE OUTER PLANETS A. What Do The Outer Planets Have In Common? è Much larger & more massive than Earth, do NOT have solid surfaces è Have huge amount of gravitational force è Each is surrounded by a set of rings -> Gas Giant = name often given to outer planets
