According to NASA
(1) A "planet" is a celestial body that (a) is in orbit around
the Sun, (b) has sufficient mass for its self-gravity to
overcome rigid body forces so that it assumes a
hydrostatic equilibrium (nearly round) shape, and (c) has
cleared the neighborhood around its orbit.
(2) A "dwarf planet" is a celestial body that (a) is in orbit
around the Sun, (b) has sufficient mass for its self-gravity
to overcome rigid body forces so that it assumes a
hydrostatic equilibrium (nearly round) shape, (c) has not
cleared the neighborhood around its orbit, and (d) is not
a satellite.
(3) All other objects except satellites orbiting the Sun
shall be referred to collectively as "Small Solar-System
Bodies".
Kuiper Belt
• Centered on the
plane of the
ecliptic.
• Extends out
about 500 AU
from the Sun.
• Consists of
comets,
asteroids, and
small icy
objects.
Oort Cloud
• Spherical
distribution of
comets and other
objects around
the Sun.
• May account for
much of the mass
of the solar
system.
Comets
• “Dirty snowballs”
• Dust, water, methane, ammonia.

Meteoroids
Meteor
The streak of light
seen in the sky as a
meteoroid is
vaporized by the
frictional heating as
it falls through the
atmosphere.
(Shooting Star!)
Meteorite
The portion of a
meteoroid that
survives to strike
the ground.
Meteoroid
A chunk of matter
moving through
space.
