Hyperion's hydrocarbons.
Interesting discovery....
I don't think those hydrocarbons
discovered on that world [near its surface] are frozen methane or ethane.
Frozen butane, propane, or pentane are more likely...
More likely still is that those hydrocarbon patches on that moon
are made up mostly of frozen "tar" and or "paraffin".
Admittedly It's not going to help Earth's petroleum needs...
But what about those hydrocarbons serving the needs of planetary terraformers
or of lunar or martian colonists?
cheers.
