Just how
big is big?
To do this, we
need to make a
model.
Start with the
Solar System.
We’ll let one inch
equal 1,000,000
miles.
Using this scale, our
Sun would be about
.9” in diameter.

The nearest planet,
Mercury, is 36,000,000
miles away from the Sun.
On our scale,
Mercury would
be 36” (3 feet)
from the Sun.

The next planet, Venus,
is 67,000,000 miles away
from the Sun.
On our scale,
Venus is 67
inches (5’ 7”)
from the Sun.

Earth is next. It is
93,000,000 miles from
the Sun.
On our scale, the
Earth is 93 inches
(7’ 9”) away from
the Sun.

Mars is next on our
journey. It is 141,000,000
miles from the Sun.
On our scale,
Mars is 141
inches (11’ 9”)
away from the
Sun.

it take to call
Mars?

The asteroids average
about 293,000,000 miles
from the Sun.
On our scale, the asteroids
would be (24’ 5”) from the Sun.

Jupiter is the first of the outer
gas giants. It is 484,000,000
miles from the Sun.
On our scale,
Jupiter would be
484 inches
(40’ 4”) away from
the Sun.

Saturn follows Jupiter. It
is 886,000,000 miles from
the Sun.
On our scale,
Saturn is 886
inches (73’
10”) from the
Sun.

Uranus is next at
1,800,000,000 miles away
from the Sun.
On our scale,
Uranus is
1,800 inches
(150’) from the
Sun.

Neptune is last planet. It is
2,800,000,000 miles away
from the Sun.
Neptune is last
planet. It is
2,800 inches

The dwarf planet Pluto is
4,600,000,000 miles
away from the Sun.
On this scale, Pluto is
4,600 inches (383’ 4”)
from the Sun.

The farthest dwarf planet, Eris,
can be as far as
12,700,000,000 miles from the
Sun.
On our scale,
Eris would be
12,700” (1,058’
- .2 of a mile)
from the Sun.

We now need a new scale. Let the
Solar System be the size of an Oreo
cookie.

On this scale, the Milky Way Galaxy
would be the size of North America.
The black hole at the center of the
Milky Way would be in the middle of
Kansas.

Galaxy (2,200,000 light years

For light to travel from
one end of the universe
to the other would take
28,000,000,000 years.
On the Oreo scale, this
would equal about
1,020,000,000,000,000
miles (or a diameter of
about 168 light years!).
