Venus Scale.

[Mac]

So as not to Hijack Caroles post.  http://forum.orpington-astronomy.org.uk/index.php?topic=8370.0;topicseen

I asked the question how big would Caroles image have to be if it was to scale.
and here is the answer.

Code Select Expand

Assuming the sun is 200 pixels wide and is 864000 miles diameter, this gives us a pixel size of 4325 miles per pixel.
the orbit sizes are shown in miles
If you were to print at 300 dots per inch then this is the distance in inches from the sun
                                                                     
                         sun       mercury      venus       earth         mars          jupiter        saturn        uranus         neptune         pluto
orbits                   864938    36000000     67200000    93000000      141000000     483000000      886000000     1784000000     2794000000      3674000000
pixels to orbit          200       8324         15538       21504         32603         111684         204870        412515         646057          849540
miles per pixel          4324.69                                                               
Distance from sun inche             27          51          71            108           372            682           1375           2153            2831
Distance from sun ft                                                      9ft           31ft           56ft          114ft          179ft           235ft


So in answer to my own question, ignoring the cale of the planets themselves and including pluto.
You would need a sheet of paper 235ft in length.

hmmmm,

my next question is,
how much black ink will you need & how much will it cost.

dont forget im ill.
i've loads of time spare at the moment.........

I'll let you know

Epson quote their coverage @ 5% on an Epson 880 as 630 pages at £ 34.99 from PC World. (other retailers are available).
so one cartridge will cover 630/20 = 31.5 pages or 31 cant really print half a page.

1 A4 page is 11.7 in assuming no overlap, so you will need 242 pages.

and 8 ink cartridges @ a cost of £280

Epson quote a print time of 1m 45 for a full photo, so assuming 1/4 of the time as its not full resolution
then the time to print it will be  just under 2 hours

Told you i was bored ill

Just print it as a negative then you don't waste ink

Mac why are you ill? What with?

Diarrhoea, I've had it for 4 days now, 
Current weight loss is about a stone
Got to book an appointment with the doctor, as there is no sign of it stopping.

I've got no other symptoms, not even feeling sick,
although Friday night, i had the shivers and was sweating like there was no tomorrow.
and at the moment i'm just feel extremely tired and hungry.

I am eating, but its not staying in that long.
