of a pea how distant would the Sun be? Pluto? Alpha Centauri?
Show More
the sun would be about the length of a cricket pitch away
and Pluto 5 miles away and alpha proxima the other end of the world
pluto would vary greatly and alpha centauri a very very long way
I hope these calculations help with the machine you're building mate.

That's a good site dylan. Put's it all in perspective!
Jesus, thats an interesting site. Never knew some of the stars were so massive and space is virtually empty!!
100 million stars in each universe and around 100 million known universes.
Nearest star the Sun just 93 million light years away and light takes 9 mins to get here (at 179,000 km per second!!!) whilst the 2nd nearests light take 4.5 years.
Whoaaaa!!!!

Just think, somebody somewhere counted all those stars. Can you imagine doing that?
One million, four hundred and thirty-six, one million, four... Then you have to scratch your nose and you lose count. One, two, three...
One million, four hundred and thirty-six, one million, four... Then you have to scratch your nose and you lose count. One, two, three...
The sun would still be 93 million miles away, give or take. Why would the sun be anwhere different just because Brown turned the world to pea?
That should be 100 BILLION not million (stars in a galaxy, and known galaxies)
Being very inerested in this subject, here's some stuff I've gleaned.
If the earth was the size of say a grain of sugar, mercury would be about the size of a grain of salt. The Gas giants the size of peas or maybe even grapes. The sun about football sized.
Venus would be a few feet away, the sun about 20 yards, Pluto, (the size of a grain of salt) about a mile away.
Assuming your grain of salt (earth) is in London, the nearest star (Proxima Centauri) would be roughly in Athens.
Galaxies exist in clusters sort of grouped, a bit like DNA strands. The Milky way (our galaxy) is about 70,000 light years across - that is, if you were in a car travelling at 186,000 miles a second, it would take you 70,000 years to cross. At the same speed it would take about 1 million years to get to the next nearest galaxy.
Galaxies occasionally collide, it takes 10's of 1000's of years for this to actually take place, and contrary to scaremongering stupid Discovery documentaries I have seen, nothing much happens....
Imagine standing at one end of the M11 (Cambridge) and throwing a bucketful of sand towards London, and doing the same at the other end. The chances of any of the grains actually hitting each other, or even getting close, are pretty slim.
Although the distances between stuff is vast, it is now reckoned that these distances are not empty, but 95% filled with Dark Matter, the composition of which is a mystery. Mainly because it can't be seen.

Whoaaaa!!!!
WRONG
I've counted it, it's 8 minutes.

Lucky my science teacher is dead then, or I'd have him tin-tacked.
What if the final Q for a million squid was how long does it take light to reach here from the sun ?
I'd leave the studio and kill him.

Approximate length of time for light to travel:
One foot 1.0 ns
One metre 3.3 ns
One kilometre 3.3 μs
One statute mile 5.4 μs
To Earth from geostationary orbit 119 ms
The length of Earth's equator 134 ms
To Earth from the Moon 1.3 s
To Earth from the Sun 8.3 min
One parsec 3.26 y
To Earth from Alpha Centauri 4.4 y
Across the Milky Way 100,000 y
To Earth from the Andromeda Galaxy 2.5 million y
Happy 2006 to you all

Yes, i was typing and not thinking. 186,000 miles per second, 7 times around the globe!!!
8.3 minutes according to the post above yours
So my 8 minutes is closer than somebody elses 9 minutes
I can sleep okay now.
Have you got sun blindness ?

someone once said there are more stars up in the sky than grains of sand on the earth, i just cant get me head round that.

I read somewhere that figure has been recalculated to be ONE THOUSAND stars per grain of sand.....?

...at least!
Billions of galaxies each containing billions of stars.
We are not alone! :0

They are actually sending a rocket to the sun
but they have to go on a night-time because of the heat ;)

You can readily calculate the grains of sand but the stars......
Totally beyond human comprehension.

it was Carl Sagan who said the stars/sand thing - at least that's where i first heard it.

Just remember that you're standing on a planet that's evolving
And revolving at nine hundred miles an hour,
That's orbiting at nineteen miles a second, so it's reckoned,
A sun that is the source of all our power.
The sun and you and me and all the stars that we can see
Are moving at a million miles a day
In an outer spiral arm, at forty thousand miles an hour,
Of the galaxy we call the "Milky Way".
Our galaxy itself contains a hundred billion stars.
It's a hundred thousand light years side to side.
It bulges in the middle, sixteen thousand light years thick,
But out by us, it's just three thousand light years wide.
We're thirty thousand light years from galactic central point.
We go 'round every two hundred million years,
And our galaxy is only one of millions of billions
In this amazing and expanding universe.
The universe itself keeps on expanding and expanding
In all of the directions it can whizz
As fast as it can go, at the speed of light, you know,
Twelve million miles a minute, and that's the fastest speed there is.
So remember, when you're feeling very small and insecure,
How amazingly unlikely is your birth,
And pray that there's intelligent life somewhere up in space,
'Cause there's bugger all down here on Earth.

I think I'm correct in stating that on a Neutron Star a buck full of sand would be more difficult to lift than Mount Everest
Yes, because Everest is on Earth so it would be too far away.
a Lad came home from school and said to his tight fisted Dad
"Dad they say I need glasses "
DAD --"Who said this ?"
Lad " The school said it , I had an eye test today and they said you will have to buy me some glasses "
DAD " Buy !!!!!!!! :0 "
DAD "Come here son " ...takes him outside and points up at the sky
DAD " What's that son ? "
Lad " Its the Sun Dad "
Dad " Well that's 93 million miles away - How far do you f***** want to see !! " ;-)

Seems I couldn't prove the sand theory anyway.....To reach the liquid interior of a Neutron Star one would have to drill through it's crust 1 mile thick and 10 billion times stronger than steel
Might need something a bit more industrial than a Black & Decker then
how the f,in ell can anyone say how many grains of sand there are on earth....
