A little perspective

I saw a picture of solar flare this morning comparing it to the size of the Earth. Years ago as a kid I used some old mainframe stream paper to ‘draw’ the solar system at scale (1/1 000 000 000 000). That really puts the whole solar system into perspective (about 9 meters long to fit Pluto on furthest point). The following things could/can be observed using stuff at this ‘scale’.

Scale 1:1 000 000 000 000
Object Description
The Sun A little ball of 1 millimeter in diameter
Earth would be 15 centimeters away from the sun (Moon about 0.4mm away from Earth)
Jupiter about 0.8 meters away (and 0.15mm in diameter)
Saturn about 1.3 meters (rings about 0.2mm in diameter)
Neptune about 4.5 meters
Pluto around 6 meters (average, varies from 4.4m to about 7.3m)
Voyager 1 is about 18 meters away
1 light year is about 11 kilometers away (10.8km)
Proxima Centauri (The closest star) would be about 45 kilometers away!
Sirius (The brightest star) about 93 kilometers away!
Betelgeuse about 6940 kilometers away! (diameter roughly 1 meter estimate)
Alnilam (Epsilon Orionis, middle star of the Orion belt) about 14 000 kilometers away
The largest star known (estimated) has a diameter of about 1.5 meters
Milky way galaxy diameter about 1 000 000 kilometers!
Andromeda galaxy about 24 000 000 kilometers away!!
Speed of light about 1 meter per hour!!!

Kinda put things into perspective – especially the speed of light
