if our solar system were 1milimeter long. how big will the milky way be?

Question

science question

Answer 1

Do the sum

The Solar system is about 10 light hours across (pluto is about 5 light hours away from the sun).

10 light hours is approximately 1000th of a light year (let's use nice round numbers)

Therefore in the model, 1mm = 1000th light year

Therefore 1 lt yr = 1 metre

Galaxy is 100,000 lt yrs approx.

Therefor in the model it is 100,000 metres

= 100 kilometres (about 60 miles)

So, if the Solar System is 1 millimetre (25th inch), the Milky Way is about 100 km (60 miles) across.

Food for thought.

(Wow, dumb blonde thinks the Solar System is the Milky Way. Yikes.)

Answer 2

If the diameter of Pluto's orbit was 1 mm., then the diameter of the Milky Way would be about 100 km. But the definition of the size of the solar system is a bit arbitrary. There are probably objects orbiting the Sun nearly 2 light years away. If you use this definition of the size of the solar system, and its diameter is 1 mm., then the diameter of the Milky Way would only be 25 metres.

Answer 3

Hi. The Milky Way is about 100,000 light years across. The Solar System is about 1 light DAY across. How many days are there in 100,000 years.

Answer 4

I mean you should try to do the mathamatics??? But first do you actually know how long the SOLAR SYSTEM is??? And if the solar system was only 1 milimeter long than think how big our Earth would actually be!

Answer 5

if a roster is on the peak of a barn roof .when it lays an egg witch way will the egg roll off too the north or to the south ?

Answer 6

isn't our solar system called the milky way? if so, it would be 1 milimeter long.

Answer 7

like 3 miles. maybe more. still pretty (see: VERY) big.

Answer 8

about tree-fity

Answer 9

i wud say one meter.. which is really big..
