I have found it to approximately be 14 hrs.
I ask the community to tell me their measurements of one Droonian day and tell me whether I am correct or wrong.
angular velocity = 0.0001246663751424521 radians/second
1/0.0001246663751424521 = 8021.40913183153 s/rad
8021.40913183153 * 2pi = 50400.00000000003 seconds per revolution
50400/60 = 840 minutes or 14 hours.
@destroyerP Hehe.It was the best adjective relating to Droo that I could think of.
idk why but it's hilarious
