Inner Planets called Rocky planets or terrestrial planets Mercury Smallest Planet and closest to the sun. No moons Rotation-spin on its axis 59 days Revolution- orbit around the Sun - its year is equal to 88 Earth days Video link https://www.youtube.com/watch?v=6KY-oB2i9lo

2. Venus -Virtually the same size, mass and Density as Earth -Sun rises in the west and sets in the East because it rotates opposite to Earth -One day on Venus is about as long as a year on Earth Video link https://www.youtube.com/watch?v=h8KrQuPklAw

-Hottest surface - the atmosphere is a thick cloud of CO2 (464° C) holds the heat -Rains sulfuric acid -No oceans, Active volcanoes -No Moons -Typically the 3rd brightest object in the sky(#1 = Sun, #2 = Moon)

3. Earth Just the right distance from the sun so temperatures do not completely freeze or boil away the water. Gravity holds the atmosphere. Rotation 24 hours; Revolution = 365.25 days. Video link https://www.youtube.com/watch?v=YMY_-xYmJvE

4. Mars Last Inner planet Thin atmosphere and further from the sun so it is a cold planet Water is in solid form-ice Largest volcanoes & 2 moons Rotation is 24 hours and 37 minutes – Similar to the Earth. Revolution takes 1 year, 322 days Video link www.youtube.com/watch?v=IEDqqy5IRFU

Outer Planets – Gas Giants Jupiter -Largest planet -Made of hydrogen and helium similar to the sun -Great red spot is a large storm -Thin ring around the planet -Gives off heat Video link https://www.youtube.com/watch?v=c-RR5mTSKmQ

-Rotation- almost 10 hours -Revolution- about 12 years -62 moons (Planetary Satellites) Video link https://www.youtube.com/watch?v=c-RR5mTSKmQ

Saturn - 2nd largest planet -Largest rings made of ice and particles -Gives off heat -Made of hydrogen and helium -Least dense-floats in water -Rotation- almost 11 hours -Revolution- about 30 years -33 moons (Planetary satellites)

Saturn – video link https://www.youtube.com/watch?v=MS9D9CzwPQU

Uranus (your-an-us) -Tipped on its side -Revolution- about 84 years -One pole is in darkness for half of a Uranus year -Thin rings -Rotation- about 17 hours -Made of hydrogen and methane gas -27 moons

Neptune - Atmosphere is similar to Uranus -Gives off heat which creates winds -Warm gas rises and cool gas sinks which sets up the wind patterns -Narrow rings -Rotation- about 16 hours -Revolution- about 164 years 13 moons

Dwarf planets Pluto -Too small and the orbital path is different from the other planets -Revolution-248 years -Very cold Video link https://www.youtube.com/watch?v=FqX2YdnwtRc

Constellations I. What are constellations A. Manmade designs using stars as coordinates in the picture. 1. First catalogs of the stars date from 1830BC. 2. Modern names are from records written by Ptolemy about 100 AD. 3. Used in astrology (predicting the future), mythology. 4. Southern hemisphere has different constellations which were identified in the 1500-1600AD.

Constellations II. Modern use of constellations A. IAU (International Astronomical Union) divided the celestial sphere into 88 official constellations. 1. Allows area mapping of the sky 2. Continues use of Greek-Roman names https://app.discoveryeducation.com/search?Ntt=constellations
