Solar System Scratchpad

[Boiler Plate]

Second large moon of Saturn. The brightest and smoothest known body in the solar system. Has active ice geysers that feed Saturn's rings and enter its atmosphere (making it the only Moon to affect its parent's composition) and neighboring moons.

Timeline[edit | edit source]

100 Million Years Ago[edit | edit source]

It is possible that Enceladus formed at this time or later. This may have been enough time for life to develop though.

Earlier History[edit | edit source]

Enceladus likely didn't exist, or existed elsewhere. At some point, other moons may have existed. These may have been involved in a collision and formed a debris disk, with Enceladus and its neighbors forming from the remains.

Later History[edit | edit source]

  • Discovered in 1789 by William Herschel.

1900 AD[edit | edit source]

Enceladus was the second known moon from Saturn out of 9, also known as Saturn II.

Modern History[edit | edit source]

  • Visited by Voyager 1 and 2 in the 1980s.
  • Cassini flybys started in 2005, discovering plumes venting from the south polar region.
  • Evidence

  • Tiger Stripes - Four parallel ridges on Enceladus related to cryovolcanism.
  • Labtayt Sulci - A system of deep fractures on Enceladus first discovered by Voyager 1 and then photographed in detail by Cassini. It is about 164 km long, 4 km wide, and 1 km deep.

March 2008 Flyby[edit | edit source]

  • Nearby (30 miles) flyby over more active south pole close enough to "taste" Enceladus's plumes.
  • Cosmic Dust Analyzer instrument malfunctioned during flyby.
  • Went through icy geysers at an altitude of 120 miles
  • Found the north pole much more ancient than south pole
