Astronomy

Chapter 1

Lesson 1

Astronomy

- It is the study of our universe. (planets, stars, moons, nebulae, galaxies, etc.)

- Astronomy is the phenomena that originate in space. (supernova explosions, gamma ray bursts, cosmic radiation, etc.)

- It is also the physics, chemistry and evolution of all the objects listed.

- Muggles consider astronomy to be a natural science.

The Solar System

- Earth is located within the Milky Way galaxy.

- In the Milky Way, there are billions of stars

- The milky way is comprised of eight planets, all of which orbit the Sun. (simply just meaning that all eight planets travel around the Sun in an elliptical rotation)

- All of the planets move in a counter-clockwise direction, but they each go at their own place.

Two Parts of the Solar System

- Both are separated by the Asteroid Belt

Inner Solar System- Mercury, Venus, Earth, Mars.

Outer Solar System- Jupiter, Saturn, Uranus, Neptune.

Asteroid Belt

- Located between Mars and Jupiter.

- It is made up of over 7,000 asteroids

- Orbits the Sun

- Contains asteroids of various shapes and sizes.

Star

- A star is a ball of hydrogen and helium that has enough mass to maintain nuclear fusion at its core.

- It’s the nuclear fusion that makes the star luminous in our night sky.

- Since the beginning of recorded time, stars have played a large role in religion and even navigation.

- The North Star was called the North Star because it always points you north.

- In ancient civilizations, people noticed patterns in the sky called constellations.

- In 1929, the International Astronomical Union officially recognized 88 constellations.

- To date, these are the only “official” constellations.

- The Big Dipper is not an official constellation because it is in an Ursa Major. It is not a constellation in its own right.
