As described by the Ark Starmap:
Though technically not a planet, Ellis XIII is considered a local mascot. This protoplanet's unique shape has given it the nickname "Pinecone".
Galactic Guide: Ellis:
The outermost planet in the system, Ellis XIII, is known locally as Pinecone due to its strange shattered rock surface. Pinecone is rich in heavy minerals and is a popular destination for long-haul miners, many of whom transport ores all the way back to Earth itself for resale.
