1 Chapter 25.1: Models of our Solar System Objectives: Compare & Contrast geocentric and heliocentric models of the solar sytem. Describe the orbits of planets explain how gravity and inertia keep the planets in orbit. Name the components of the solar system.

2 Answer these questions on the top of your Guided Reading Worksheet. 1. What is the difference between the geocentric and heliocentric models of the solar system? Which one is accurate? 2. Saturn is 10 x farther from the sun than Earth. What is the distance between Saturn and the sun in AU? In kilometers or miles? (show your work) 3. The Andromeda galaxy is 2.5 million light years away. How long does it take the light from Andromeda to reach us?

3 1. Models of the Solar System Ancient people thought E. is stationary; Sun, planets, & stars move around E. Observed 5 planets: Mercury; Venus; Mars; Jupiter; & Saturn

4 A. Geocentric Model = Earth is the center of the universe (a sphere). Stars & planets orbit E. each day. Who: Most ancient Greeks later Ptolemy (Egyptian 140 AD) maps out position of planets with this model (Accepted for ~1400 yrs) Earth is stationary. fixed # of stars.

5 A. Geocentric Model: Ptolemy s Epicycles When E. passes planets they look like they are moving backwards relative to us for a while. This apparent (not actual) backward motion in known as retrograde motion. Ptolemy didn t believe E. moved (it was the center of the universe) so he couldn t explain this backward motion of planets. That s where Epicycles come in but they are not real.

6 Geocentric model cont. Problems with Geocentric Model 1. It s WRONG! But also 2. Earth is not stationary (It rotates) 3. It could not explain the motion of planets so Ptolemy created EPICYCLES to explain planetary motion.(especially RETROGRADE motion) See Epicycles: zebu.uoregon.edu/.../121/lecture-3/ptolemy.html

7 B. Heliocentric Model = Sun is the center of universe. Earth orbits the sun. Aristarchus Ancient Greece Proposes theory. Not widely accepted. Nicolaus Copernicus 1543 AD Thinks Aristarchus had the right idea and develops it into a publication. Problem w/copernicus s Model: Orbits are not perfect circles. Retrograde Motion of Mars

8 B. Heliocentric Model: Galileo Galileo 1616, 1632 Publications Explains how Inertia & Gravity keep planets in motion. Finds Evidence to Support Copernicus s Heliocentric Theory Venus has phases (new & full can t be seen b/c sun blocks Venus must move around the sun, not Earth). Jupiter s moon s: Galileo discovers 4 moons orbiting Jupiter NOT EARTH (Earth must not be at the center of the UNIVERSE). Reward: House arrest for life.

9 2. Planetary Orbits Johannes Kepler (1600) revises Copernicus s model Orbits are not circles they re ELLIPSES (OVAL) Planets orbit the sun in a plane called the: ECLIPITIC

10 2. Planetary Orbits: Inertia & Gravity keep planets moving in a curved path. 1. INERTIA: Newton 1 st Law of Motion tells us that planets want to keep moving in a straight line forever (in motion stay in motion) 2. GRAVITY: The Sun s gravitational pull keeps planets fr. Moving in a straight line. This tugging creates the curved path. Gravity is an attractional force between two masses. Gravity: pulls on Earth Inertia: Earth want to keep moving in a straight line (moving keep moving, in same direction). The force that prevents this: Gravitational force from sun.

11 3. Components of the Solar System Solar System = Sun, planets, their moons (satellites),asteroids, kuiper belt objects, & comets (All orbit sun) Sun Mercury Venus Earth Mars Asteroid Belt Jupiter Saturn Uranus Neptune * Pluto Kuiper Belt Objects Comets

12 3. Components of the Solar System A.U. (Astronomical Units) = average distance between Earth & sun (1 AU) 93 million miles (149.6 million km) Used to measure distances w.in S.system Jupiter is 5 AU from sun its 5 x farther fr. Sun than E.

13 Planet Distances Within the Solar System Distance from Sun in kms Distance in A.U.s Mercury 57,900, Venus 108,200, Earth 149,600,, Mars 227,900, Jupiter 778,400, Saturn 1,427,000, Uranus 2,896,600, Neptune 4,520,000, Pluto 5,899,900,
