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.


100 Million Years Ago[]

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

Earlier History[]

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[]

  • Discovered in 1789 by William Herschel.

1900 AD[]

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

Modern History[]

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

March 2008 Flyby[]

  • 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
