Loge (Saturn moon)

Discovery and designation

The discovery of Loge was announced on 26 June 2006 by a team led by Scott S. Sheppard and David C. Jewitt, along with Jan Kleyna and Brian G. Marsden, based on observations obtained between January and April 2006. The original announcement and related notices are associated with the discoverers' pages and discovery circulars; see the team pages for more detail: Scott S. Sheppard and David C. Jewitt. After confirmation of its orbit, the moon received the provisional designation S/2006 S 5 and later the permanent number and name Saturn XLVI (Loge).

Orbit and physical characteristics

Loge follows a distant, inclined, and moderately eccentric path around Saturn. Key orbital parameters include:

• Average orbital distance (semi-major axis): about 23,142,000 km from Saturn
• Orbital period: roughly 1,314.364 days
• Inclination: approximately 166.5° to the ecliptic (about 165.3° relative to Saturn's equator)
• Eccentricity: around 0.1390

These values are drawn from published orbital solutions and observatory reports; for detailed element sets and updates consult orbital parameter lists and circulars: orbital elements and orbital parameters. The moon's small size implies a low brightness (high apparent magnitude), and its surface composition remains unmeasured except by color indices inferred from photometric observations.

Group membership and origin

Loge is grouped with Saturn's Norse satellites, a collection of distant, retrograde moons that share broadly similar inclinations and orbital distances. Such groups are interpreted as possibly originating from one or more larger bodies that were captured by Saturn's gravity and later fragmented by collisions. Studies of these groups—by comparing orbits, colors, and sizes—help researchers reconstruct collisional histories and capture mechanisms of the outer satellite system.

Name and mythology

In April 2007 the moon was named Loge after a figure from Norse mythology, often rendered as Logi or Loge, a fire giant and son of Fornjót. The name honors the mythological tradition used for this group of Saturnian moons. In popular references Loge is sometimes confused with the trickster god Loki; the naming authorities distinguish the two figures when assigning names to planetary satellites. See the naming citation and mythological background: naming citation and mythological source.

Scientific significance

Although individually small, moons like Loge are scientifically valuable because they probe processes of satellite capture, dynamical evolution, and collisional fragmentation in the outer reaches of planetary systems. Continued astrometric monitoring refines their orbits, and photometric surveys improve estimates of size, albedo, and surface properties. Future observations with larger telescopes or space missions could yield more precise information on rotation, composition, and potential relationships to collisional families.
