Instructions for
Scale of the Universe activity:
1. You will be given a tab for an object in our
universe.
2. Think about the size of your object and align
yourself with your classmates in the back of
the room
3. Smallest object should be closest to the
Astronomy bulletin board. Largest objects
should be closest to the sinks.

An atom has a small, dense nucleus composed of neutrons and protons.
Our Sun’s diameter (1,380,000 km) is roughly 1.8 times longer than our
moon’s orbit diameter. •
All Oort Cloud objects, from planets in our solar system to far-out comets,
are bound by gravity to our massive sun/star.
On a clear dark night, we can see a few thou- sand star/suns in our
immediate “neighborhood” with the naked eye.
Our star “neighborhood” spirals with billions of other stars in our home
Milky Way galaxy.
Our Milky Way circles with numerous neighboring galaxies to form a Local
Group.
Our Local Group rotates near the outer edge of many other groups of
galaxies with the Virgo Group near its center. This huge, gravitationally
bound “group of galaxy groups” is called the Virgo Supercluster.
The Virgo Supercluster floats like a dust mote among 100 billion other
galaxies that comprise the observable universe.
Homework
 Find out the size of your object. Try to find
out both the diameter and circumference of
your object. If it is not spherical imagine a
sphere around it and report back next class.

Large scale structure of the
universe

QxPI
 This is a five minute large-scale structure of the
Universe shown in 3 different scientific
observation projects:
 Sloan (Digital Sky Survey), Millenium (3D model of
the universe) and Filaments grown process
simulation.
Exit note
1. Which is larger, Mars or the Moon?
2. Which is larger, a galaxy or a super cluster?
3. Which is larger the Solar System or an Oort
Cloud?
Homework reminder: Investigate the size of
your object in metric measurements.
