The Greater Shell Nebula is a reflection nebula located in the central part of Coro Sector, within the Empty Stars.

Description (Specifications)[edit]

The Greater Shell Nebula is a large dim group of gases and dark clouds measuring around seven parsecs coreward-rimward by around six parsecs spinward-trailing. The nebula has a large "tail" extending for nearly five parsecs to rimward.

  • It is classified as a reflection nebula and is primarily formed of ionized gases, thrown off by the stars at its center many millennia ago.
  • The gases consist of about 90% hydrogen (H2), with the remainder made up of helium (He), oxygen (O2), nitrogen (N2), and other elements. The clouds have a mean density of 10–6 particles/cm³. Its central regions are relatively denser.

A trinary star systems lie at its core:

Hex Location: 1007 Coro Sector. 2 Gas Giants.
