Lyceum B - Astronomy - Week 11 - Introduction/ Orrery
- Feb 9, 2022
- 2 min read
Our Astronomy section is based on the book - “How the Universe Works : 100 Ways Parents and Kids Can Share the Secrets of the Universe”.
The science has advanced beyond the material in the book, but the format remains as fresh today as when it was published. Many of the experiments and demonstrations we use come directly from this book.
As with all of our topics, we are only covering this material on the primary level. We are not looking to become experts on any of this, just to gain enough knowledge to aid in our understanding of our world. We will cover this material through lectures, videos, in class reading material. This session is heavy on demonstrations and experiments illustrating each topic. You are allowed to bring your children, of appropriate age, (see previous note about registering up to 4 family members at initial membership sign up) to these classes as long as they do not disrupt the learning experience for other Lyceum members.

Lyceum B - Astronomy - Week 11 - Introduction
The word “solar” refers to the sun. Thus, the solar system includes the sun and all of the heavenly bodies that go around the sun. These include not only the nine planets that orbit around the sun with their own (200+ in total) moons, but also comets, asteroids and meteoroids (which number in the millions.)
Our solar system is part of the Milky Way.
Which is part of the Universe.
Much of the stuff flying around the sun in our solar system is debris left over from the birth of the Sun and planets 4.6 billion years ago.
Scientists believe that the Sun and planets may have been formed inside a huge cloud of gas and dust in space. The gas and dust in the center of the cloud were compressed together and that pressure created a great deal of heat. And that became our Sun. The planets formed around the same time.

An Orrery
The planetary model known as the ‘orrery’ takes its name from Charles Boyle, the fourth Earl of Orrery. The London instrument maker John Rowley (circa 1668 - 1728) made the first orrery for Charles Boyle around 1713, but planetary models have existed since ancient times - cam.as.uk
