History

• Jan Oort Found the Oort cloud in In 1950 he had
  the idea that there must be a reservoir of
  comet-like objects orbiting very far from the
  Sun, of frozen comet nuclei way out beyond the
  planets, from 2000 to 50,000 AU from the Sun
• From Jan Oort Last name.
• Place a photo (with a caption) of the planet
  symbol and if possible, the discoverer as well.

Solar System

• a hypothesized spherical cloud of comets which
  may lie roughly 50,000 AU, or nearly a
  light-year, from the Sun.

Regions of the Oort cloud

• The Oort cloud is thought to comprise two
  separate regions a spherical outer Oort cloud
  and a disc-shaped inner Oort cloud. Objects in
  the Oort cloud are largely composed of ices, such
  as water, ammonia, and methane. Astronomers
  believe that the matter composing the Oort cloud
  formed closer to the Sun and was scattered far
  out into space by the gravitational effects of
  the giant planets early in the Solar System's
  evolution.

Composition and Atmosphere

• Describe the core and surface composition of your
  planet.
• Describe the composition of the atmosphere if
  any. If your planet does not have an atmosphere,
  simply state your planet does not have one.
• Include a photo (with a caption) of the inside of
  your planet (found on the enchantedlearning.com
  website).

Orgin

• The Oort cloud is thought to be a remnant of the
  original protoplanetary disc that formed around
  the Sun approximately 4.6 billion years ago. The
  most widely accepted hypothesis is that the Oort
  cloud's objects initially coalesced much closer
  to the Sun as part of the same process that
  formed the planets and asteroids.
