Earth in Space Notes Part 1
Our Solar System
• Objects in our solar system move in
predictable patterns.
• The predictable movement of these objects
are determined mainly by the gravity of the
sun and planets and also by the distance
between objects in our solar system.
• Will the planets ever collide with each other
or the Sun?
• Will any moon ever collide with a planet?
• Will meteorites or asteroids ever collide with
planets?
• Why are the chances small that things collide
in outer space?
• The predictable patterns that the bodies in
our solar system move allow for us to predict
things like, days, years, eclipses, lunar phases,
and even comet passages.
New Technologies
• New and more powerful telescopes allow
scientists to see farther and farther into space.
• The new technology also allows scientists to
get more detailed images and readings about
distant planets and stars.
• New planets in other solar systems have been
discovered even though scientist can’t see
them.
• They are discovered when they pass in front of
their solar systems’ star and appear as a dark
spot when scientists are observing the far
away star.
Milky Way Galaxy
• Our solar system is part of the Milky Way
Galaxy.
• The Milky Way Galaxy is a spiral galaxy that
has arms radiating out from the center.
• Our solar system is located towards the end of
one of the arms.
