In 1619 I published Harmonice Mundi, here I derived the heliocentric distances of the planets and their periods from considerations of music

@tychoBROhe6969 Maybe I was... Mercury sure does the trick

[Johannes Kepler @jkepler1587]

Between 1617 and 1621 I published Epitome Astronomiae Copernicanae, which became the most influential introduction to heliocentric astronomy

(2/2) These observations were a huge support to @observegalileo , whose discoveries were doubted or denied by many.

[Johannes Kepler @jkepler1587]

(1/2) In 1610 I published my observations of Jupiter's satellites, "Narratio de Observatis Quatuor Jovis Satellitibus"

[Johannes Kepler @jkepler1587]

In 1606 I published "De Stella Nova" ("Concerning the New Star") on the new star that had appeared

(2/2) Copernican system is determined by the five regular solids

[Johannes Kepler @jkepler1587]

(1/2) In 1597, one of my first important pieces "The Cosmographic Mystery" argued that the distance of the planets from the sun in the

In 1610 I read about @observegalileo discoveries with the spyglass. I then published "Dissertatio cum Nuncio Sidereo", my letter of support.

@tychoBROhe6969 Always talking about yourself. Maybe if you weren't so selfish we could've gotten along, no wonder you were poisoned.

[Johannes Kepler @jkepler1587]

It was I who learned how vision worked, If you don't believe me, read my novel on the behavior of light in the telescope!

[Johannes Kepler @jkepler1587]

@RevCopernican My discoveries turned your sun centered theory into a real universe with the sun pushing the planets in non-circular orbits

[Johannes Kepler @jkepler1587]

@Tychobrain @RevCopernican Then why didn't you do it yourself? In 1600 you invited me to join your court at Castle Benátky near Prague. You needed me, admit it!

[Johannes Kepler @jkepler1587]

I hypothesized that a single force from the Sun accounts for the increasingly long periods of motion as the planetary distances increase

[Johannes Kepler @jkepler1587]

@sir1saacNewton If I hadn't defined the motion of the planets, you wouldn't have any basis of motion to start with. I saved you a lot of time Isaac!

[Johannes Kepler @jkepler1587]

@RevCopernican @Tychobrain You may have observed that planets revolved around the sun, but it was I at the young age of 27 correctly defined their exact orbits

[Johannes Kepler @jkepler1587]

@Tychobrain I know you as the guy who can't smell anything. If it weren't for my calculations your pointless observations would be unknown.

[Johannes Kepler @jkepler1587]

@Tychobrain How's the nose? Thanks for the data btw, your observations would've been useless without my calculations.

[Johannes Kepler @jkepler1587]

3. There is an exact relationship between the squares of the planets’ periodic times and the cubes of the radii of their orbits

[Johannes Kepler @jkepler1587]

2. The time necessary to traverse any arc of a planetary orbit is proportional to the area of the sector between the main body and that arc
