2 Formation of the Moonhttp://www.youtube.com/watch?v=WpOKztEiMqo&feature =related Formation of our Solar System Conservation of Angular Momentum Why are the larger, gaseous planets farther away and the smaller, rocky planets that are closer? How do we have an estimate of our solar system s age? What makes something a dwarf planet? The IAU says it is a celestial body orbiting the Sun a) massive enough to be rounded by its own gravity b) has not cleared its orbit of planetesimals.
3 Collisions dominated the early solar system (What is the key force here?) dust collects together into planetesimals planetesimals collect together into protoplanets Protoplanets gather up left over debris and became planets
4 The solar system formed from a giant cloud of rotating, cold gas and dust called the solar nebula about 4.6 billion years ago
6 The planets formed by the accretion of planetesimals and the accumulation of gases in the solar nebula
7 Which planet formed at the furthest location from the Sun where it was hot enough to boil water? A. Mercury B. Mars C. Jupiter D. Neptune E. None of the above
8 How should we categorize the objects in the Solar System?
9 Discuss size of Earth, Venus, Mars, Mercury & Moon Venus is nearly same diameter as Earth Mars is nearly half the Earth s diameter Moon is about ¼ Earth s diameter Mercury is smaller than Mars, about size of Saturn s moon T itan and Jupiter s moon G anymede
10 The Sun is the Largest Object in the Solar System The Sun contains more than 99.85% of the total mass of the solar system If you put all the planets in the solar system together, they would not fill up the volume of the Sun 110 Earths or 10 Jupiters fit across the diameter of the Sun How big is the Sun?
11 The Sun has a diameter of approximately 1.4 million kilometers. Roughly how many Earths would fit across the diameter of the A. 10 B. 100 C D. 10,000 E. 1 million Sun? 80% 3% 3% 6% 8% million
12 Where are the asteroid belts and what are their names? What is the name of the largest asteroid in the Main Asteroid belt? Discuss the VUP s. What is the name of the largest asteroid in the Kuiper belt?

22 The Inner Planets (Family Portrait)

45 Inner planets are vastly different than outer planets in terms of orbital distances
46 The Outer Planets (Family Portrait)
47 Jupiter is the Largest of the Gas Giant Planets
48 Besides being the largest planet, Jupiter is probably best known for its Great Red Spot - a hurricane-like storm that has been observed ever since the invention of the telescope.
49 Jupiter has four large moons and tens of small ones
50 Saturn has the most extensive ring system in the solar system
51 Saturn s spectacular rings are composed of fragments of ice and ice-coated rock
52 Titan is Saturn s largest moon
53 Saturn and Jupiter share the same basic structure
54 A system of rings and satellites revolves around Uranus Uranus has a hazy atmosphere with few clouds
55 Uranus tilt gives it very exaggerated seasons

64 Anatomy of a comet
65 Comets often have two tails: a thin ION tail (in a line) and a curving DUST tail (dust deviates)
66 NOTICE the colors are off, they should be: The blue tail should always be the ion (gas) tail as it fluoresces and it should be straight in a line away from the Sun. Thus the dust tail is (dang) curved and should be whitish to whitish-yellow. Comets lack tails until they enter the inner solar system. A comet s tails always point away from the Sun, no matter which way the comet is moving!
67 15 km long by 8 km wide Comet Halley nucleus
68 Meteor showers occurs when Earth passes through the dusty tail debris left by a passing comet. Dust particles burn up as they enter Earth s atmosphere, like bright light shooting from a single point in the sky.
69 Taken by an amateur astronomer, this picture shows the comet taken on October 1 as a bright green glow in the sky. The Deep Impact spacecraft will pass a mere 435 miles (702 kilometers) from Comet Hartley 2 on November 4 th, 2010 about 6:50 am PT.
