| Question | Answer |
|---|---|
| What is the famous 5,000-year-old stone circle tourist site in England? | Stonehenge |
| Which ancient civilization built the El Caracol observatory and did human sacrifices when the planet Venus was out? | The Mayans |
| Which group of people built the Big Horn Medicine Wheel in North America? | Native Americans |
| The Great Pyramids of Giza line up with which famous group of stars? | Orion’s Belt |
| What do ancient sites like Stonehenge and the Pyramids have in common? | They line up with the stars and the Sun |
| What do we call the old belief that the Earth is the center of the universe? | The Geocentric model |
| What do we call the belief that the Sun is the center of the solar system? | The Heliocentric model |
| In the old Earth-centered model, what were the extra "mini-circles" planets looped around in? | Epicycles |
| What is it called when a planet looks like it is moving backward in the sky? | Retrograde motion |
| Which historical group kept astronomy alive and advanced math by translating old texts? | Islamic scholars |
| Which great observer lost his nose in a duel and wore a fake one? | Which great observer lost his nose in a duel and wore a fake one? Tycho Brahe |
| Why does Mars look like it moves backward sometimes? | Earth is passing it |
| Who is the Renaissance scientist who brought back the Sun-centered model? | Nicolaus Copernicus |
| What is "stellar parallax"? | The way nearby stars seem to shift against background stars as Earth moves around the Sun. |
| Who actually invented the telescope? | Hans Lippershey |
| Who improved the telescope and discovered Jupiter’s 4 largest moons? | Galileo Galilei |
| Who was burned at the stake for saying stars are just other suns with planets? | Giordano Bruno |
| Who spent his last 8 years under house arrest for defending the Sun-centered model? | Galileo Galilei |
| What oval shape do planets actually make when they orbit the Sun? | Ellipses (ovals) |
| What is the word for when a planet is closest to the Sun? | Perihelion |
| In which month is Earth moving fastest in its orbit? | January (because we are closest to the Sun). |
| In which month does the Sun look the smallest to us? | July (because Earth is farthest away). |
| Which of Kepler's laws says a planet sweeps out equal amounts of space in equal time? | Kepler’s Second Law |
| What does 1 Astronomical Unit (A.U.) stand for? | The average distance from Earth to the Sun |
| If a planet is farther from the Sun, does its "year" (orbit time) get longer or shorter? | Longer |
| If an orbit has an eccentricity of 0.000, what shape is it? | A perfect circle |
| Why do the Sun and the Moon look like they are the exact same size in our sky? | They have the same apparent size (the Sun is huge but far away; the Moon is small but close) |
| How do you find the eccentricity of a planet if the focus distance is 2.0 and the length is 6.0? | Divide 2.0 by 6.0 to get 0.33 |
| Who came up with the Law of Universal Gravitation? | Isaac Newton |
| What two things decide how strong gravity is between two planets? | How heavy they are (mass) and how far apart they are (distance) |
| Planets stay in orbit because gravity pulls them in, but what keeps them from crashing into the Sun? | Inertia (their forward speed) |
| If you move two objects twice as far apart, what happens to gravity? | It gets 4 times weaker |
| Complete the law: "For every action, there is an equal and...?" | Opposite reaction |
