+# CSS Solar System
+
+An animated model of the Solar System. The animations themselves use only CSS, and the year counter uses JS.
+
+## To run the code
+
+Navigate to the CSS-Solar-System folder in command line and open index.html.
+
+## Some Random Facts
+
+- The Planets and the Sun are not to scale. (The sun would take up most of the screen, and you wouldn't see Pluto at all.)
+- But I tried to make the rotation speed accurate.
+- Mercury rotates around the Sun every 87.97 Earth days.
+- Venus rotates around the Sun every 224.7 Earth days.
+- Earth rotates around the Sun every 365.26 Earth days, or 1 Earth year. This is 3.65 seconds in the simulation.
+- Mars rotates around the Sun every 687 Earth days, or 1.881 Earth years.
+- Jupiter rotates around the Sun every 4,332.59 Earth days, or 11.86 Earth years.
+- Saturn rotates around the Sun every 10,759 Earth days, or 29.46 Earth years.
+- Uranus rotates around the Sun every 30,688.5 Earth days, or 84.01 Earth years.
+- Neptune rotates around the Sun every 60,182 Earth days, or 164.8 Earth years.
+- Pluto rotates around the Sun every 90,560 Earth days, or 248.1 Earth years.
