    In this segment of our video book, we cover distances inside our Solar System.
    We start out with a brief history beginning with how Nicolas Copernicus used planetary retrograde motion to help move us from the Earth-centric view to the Sun-centric view of our Solar System. We work our way through the contributions made by: Tycho Brahe and his detailed observations made with mural quadrants and sextants; Kepler and his mathematics of elliptical orbits; and Galileo with his observations using the newly invented telescope. We conclude this history with Newton and his theory of gravity. Gravity gives us the first opportunity to explain the inverse square law that will play such a central role in celestial distant measurements as we move out to the stars.
    We then explain planetary parallax as an extension to triangulation and use it to determine the distance to the Moon. We also illustrate all the additional information that becomes available once the distance is known, such as diameter, area and volume. Next, we take a look at the orbit of Mars and the Earth and the distance of Mars from the Sun, followed by distances of all the planets and dwarf planets from the Sun. During this segment we cover the major moons around each planet. We then focus on the Asteroid Belt. We explain Lagrange Points and cover Jupiter’s Trojan asteroids orbiting two of these points. This takes us to Earth’s Trojan asteroid, 2010 TK7.
    We then turn our attention to the Sun. We triangulate the Sun with Venus to calculate our distance from the Sun - one Astronomical Unit. With distance to the Sun known, we calculate its diameter, surface area and volume; the length of Earth’s orbit; the Earth’s velocity around the Sun; and with that, the Sun’s mass. Next, we use Jupiter’s moon Io to calculate the speed of light and with that we calculate how long it takes the Sun’s light to reach the Earth.
    We end by adding the parallax rung to our distance ladder.

    Mr. Butler, I want to express my deep gratitude for the time you put into making these precious videos. I think I’ve watched all of them dozens of times. I suffer from PTSD and insomnia, and I find comfort in listening to your calm voice. I like your slow and thoughtful presentation, and it calms me down and helps me sleep. Sometimes I put on your videos when I wake up with nightmares at 3 AM. I find the subject matter interesting but you present it in a way that takes my mind off of my troubles without being overstimulating. You have helped me in more ways than I could ever express. Thank you, and I wish you all the best.

    Near where I live in Germany there is a solar system walk. There is a sculpture that depicts the sun, it’s about the size of a skippy ball. About 200 meters there is a post with a bronze earth, it’s the size of a marble, the moon about a hands withs with away. There are bronze sculptures of all planets like this. Its a 10 kilometer walk to Pluto. On this scale the closest star is approximately in South Afrika.

We both agree, based on our experiences: astronomers, for some important reason, are the nicest, most joyful and interesting people we have ever met. These videos simply strengthen that pejorative view, at least for me.

      hear, hear. I love the brilliant look of those CCD pictures of faraway galaxies, star clusters, nebulae, etc. BTW, the music arrangement is terrific. I really loved that version of Satie's Trois Gymnopedies. What a lovely, sedate, yet haunting version!!

    Thank you, Mr. Butler. Excellent and meticulous work.
    I do understand much better now, how it is possible to calculate these immense distances, masses, speeds. (And I do understand why I learned calculating triangles in school. It is very important.)

    How this guy never had a primetime science show or narrated the universe i will never know?? Don't get me wrong the dirty jobs guy does a great job talking about supernovae and hawking radiation but this guys voice is spot on.

    I always thought I knew everything about astronomy. But after listening to some of your lectures, I realized I know close to nothing.
