Astronomy:List of geological features on 21 Lutetia

Short description: None

21 Lutetia

This is a list of named geological features on 21 Lutetia. There are 37 officially named features on Lutetia, of which:

• 19 (51%) are craters,
• 8 (21%) are Regiones,
• 3 (8%) are Labes,
• 2 (5%) are Fossae,
• 2 (5%) are Rimae,
• 2 (5%) are Rupes, and
• 1 (3%) is a Dorsum.

21 Lutetia was flown by in July 2010 by the Rosetta spacecraft, while en route to comet 67P/Churyumov–Gerasimenko. During this visit, Rosetta imaged Lutetia with a resolution of 60 metres (200 feet) per pixel. As Lutetia is named after the Roman town that would later become Paris, most features on Lutetia are named after places in Europe during the Roman era.

Craters

Impact craters on 21 Lutetia are named after cities in Europe around the Roman era. Based on the images taken of the northern side of Lutetia by Rosetta, it is suspected there is a large crater named Suspicio crater on the southern side of Lutetia, however it has not been directly imaged, so it remains unconfirmed, and therefore is not included in this list.
