+# [The Solar System - Jumbled Planets](https://www.codewars.com/kata/the-solar-system-jumbled-planets "https://www.codewars.com/kata/678e32f27625ec1b6a0e5976")
+
+Oh, no! The celestial bodies orbiting the sun are all jumbled up!
+<h2>TASK</h2>
+Given the entire Solar System in the form of a list. Return a new list which has either <code>'<'</code>, <code>'>'</code>
+or <code>'='</code> depending on whether the planet is smaller than the planet on its left or not. You have to start comparing from the
+second item, because the first has nothing on its left.
+
+However, there are also asteroids in the Solar System. All asteroids are smaller than all the planets. If two asteroids are found beside
+each other, the leftmost one will depend on the celestial being on the left of it. The one on the right will have `'='`.
+
+The Solar System might be empty.
+
+The celestial bodies stand in the order (size ascending):
+
+```Asteroid < Pluto < Mercury < Mars < Venus < Earth < Neptune < Uranus < Saturn < Jupiter```
+
+<b>Important: the dwarf planet Pluto is also included in the Solar System</b>
+
+<h2>EXAMPLES<h2/>
+
+```
+["Mars", "Asteroid", "Venus", "Jupiter", "Asteroid", "Earth", "Pluto"] -> ['<', '>', '>', '<', '>', '<']
+# Asteriod is '<' Mars
+# Venus is '>' any Asteroid
+# Jupiter is '>' Venus
+# Any Asteroid is '<' Jupiter
+# Earth is '>' the Asteroid
+# Finally, Pluto, being a dwarf planet, is '<' Earth
+
+["Asteroid", "Asteroid", "Asteroid", "Earth", "Jupiter"] -> ['=', '=', '>', '>']
+# Here, the Asteroid is '=' to the Asteroid on its left
+# Again, it is '=' because there is another Asteroid on its left
+# Earth is '>' than the Asteroid
+# Finally, Jupiter, being the king of the planets, is '>' than Earth
+
+["Mercury", "Venus", "Earth", "Mars", "Asteroid", "Jupiter", "Saturn", "Uranus", "Neptune", "Asteroid", "Pluto"] -> ['>', '>', '<', '<', '>', '<', '<', '<', '<', '>']
+# Atleast here the Solar System is how it's supposed to be!
+```
+
+<h2>NOTES</h2>
+· There will never be more than one of anything except asteroids
+
+· The Solar System will never contain anything outside:
+
+```
+["Asteroid", "Pluto", "Mercury", "Mars", "Venus", "Earth", "Neptune", "Uranus", "Saturn", "Jupiter"]
+```
