DEFINATION OF UNIVERSE

• Whole cosmic system of matter and energy of which
  Earth is a part. Its main constituents are
  GALAXIES,within which are stars and stellar
  grouping and nebula. The universe is governed by
  four fundamental forces the STRONG FORCE,the
  WEAK FORCE,the electromagnetic force, and
  GRAVITATION. Numerous theories have been proposed
  for the origin and structure of the universe.

4
GALAXY

• 1. a. Any of numerous large-scale aggregates of
  stars, gas, and dust that constitute the
  universe, containing an average of 100 billion
  (1011) solar masses and ranging in diameter from
  1,500 to 300,000 light-years. Also called nebula.
  
• b. often Galaxy The Milky Way.
• 2. An assembly of brilliant, glamorous, or
  distinguished persons or things a galaxy of
  theatrical performers.

5
SOLAR SYSTEM

• The Solar System was formed about 4,560 million
  years ago. It is made up of the eight planets,
  their moons,comets and other bodies. These all
  orbit around our Sun,to which they are attracted
  by gravity

MOON

1. The natural satellite of Earth, visible by
   reflection of sunlight and having a slightly
   elliptical orbit, approximately 356,000
   kilometers (221,600 miles) distant at perigee and
   406,997 kilometers (252,950 miles) at apogee. Its
   mean diameter is 3,475 kilometers (2,160 miles),
   its mass approximately one eightieth that of
   Earth, and its average period of revolution
   around Earth 29 days 12 hours 44 minutes
   calculated with respect to the sun.
2. A natural satellite revolving around a planet.
3. The moon as it appears at a particular time in
   its cycle of phases a gibbous moon.
4. A month, especially a lunar month.
5. A disk, globe, or crescent resembling the natural
   satellite of Earth.

9
ASTEROID

• A body smaller than a planet and made of
  rock,metal,or other minerals. There is a large
  belt of asteroids between Mars and Jupiter.

10
METEORORSHOOTING STAR

• A chunk of rock or metal that enters EARTHS
  atmosphere and burns up in a fiery show.

11
METEORITE

• A chunk of rock or metal that has fallen to Earth
  from beyond its atmosphere.

12
METEOROID

• A chunk of rock or metal moving through space.

13
COMET

• A celestial body, observed only in that part of
  its orbit that is relatively close to the sun,
  having a head consisting of a solid nucleus
  surrounded by a nebulous coma up to 2.4 million
  kilometers (1.5 million miles) in diameter and an
  elongated curved vapor tail arising from the coma
  when sufficiently close to the sun. Comets are
  thought to consist chiefly ammonia, methane,
  carbon dioxide,and water.

14
Great Comet

• The definition of a great comet could obviously
  be quite subjective. However, any comet which
  becomes bright enough to be noticed by people who
  are not actively looking for it and becomes well
  known outside the astronomical community may come
  to be known as a great comet.

15
HALLEYS COMET

• A comet with a period of approximately 76 years.
  The first comet for which a return was
  successfully predicted, it last appeared in 1986.

16
COMET DONATI

• It was a comet named after the Italian astronomer
  Giovanni Battista Donati who first observed it on
  June 2, 1858. The comet is considered a
  non-periodic comet . After the Great Comet of
  1811, it was the most brilliant comet that
  appeared in the 19century . It was also the first
  comet to be photographed. It was nearest the
  Earth on October 10,1858.
