Many students gone here and there. You are going to have to do a lot on your own to get caught back up. Hopefully, this website will help.

Red marker shows Tycho’s island
Tycho built the castle and observatory Uraniborg on Hven in 1576 (with a laboratory for his alchemical experiments in its cellar) and then Stjerneborg nearby in 1581. Unusual for the time, Tycho established Uraniborg as a research centre, where almost 100 students and artisans worked from 1576 to 1597.[

Tycho’s view of our solar system.
SO what is the slope of this line?
Even my AP Physics girls started to wear down in late April. HANG IN THERE! It will be VERY worth it to you.
Mar’s apparent Retrograde motion if you are using the Ptolemic system. This required early 16th century Ptolemic astronomers to add epicycles (circles within circles) to planet’s orbits.
THe true reason (using Kepler’s system) why Mar’s appears to have retrograde motion.
Kepler’s geometric shapes within shapes which laid out the distances from each planet to the sun.
The Harmony of the Sphere’s. Kepler’s attempt at making sense of the solar system and homage to God’s beautiful design.
Kepler’s museum in Prague. Not nearly impressive as it should be considering he changed mankind’s view of the solar system.
Carl gives his respects.
The Kepler telescope is launched in 2009.
The Kepler observatory is “specifically designed to survey a portion of our region of the Milky Way galaxy to discover dozens of Earth-size planets in or near the habitable zone and determine how many of the billions of stars in our galaxy have such planets”. A photometer continually monitors the brightness of over 145,000 main sequence stars in a fixed field of view. This data is transmitted to Earth, then analyzed to detect periodic dimming caused by extrasolar planets that cross in front of their host star. It’s already found almost 3000 candidates.
