smile ...................NO ONE HAS measured it

It changes with time as the matter changes to energy

also it changes with solar flares that can measure into
several miles...........................

None of the recorded answers are ACCURATE
No one has measured...if any one has,,,who is there to verify or come with a different answer......

NO-one
perhaps they have made a GUESSTIMATE ( pick a number )
like say a million miles
a million miles + 1
a million miles + 20
a million miles + a million miles
a million miles - 10 miles

pick any selection or come up with any number you like

you can see it thru a small hole made with a PIN
you can see it Thru Hubble telescope
you can see it with the EYE
you can see it in Printed form/ pictures/ media / digital-web sites

BUT no one has really measured it here is why with an example

can you measure some-one's height / waist / when you are several thousands miles away ??????????????

no - RIGHT

A human is usually same size at any day - within inches
Human is average 70 inches tall and perhaps 30inches wide

then
HOW can anone determine with DEFINITE ACCURACY
the diameter of something that is changing so drastically every second. ..................................

is the diameter really of so much of importance....
if yes for who really are you asking the question

you can say it is 8 light minutes away. based on the time taken by Photon to travel. ( speed of light particle )
but photons also do not travel in straight lines--so that is also not definately accurate................................. keep wondering

incredible diameter about 1,400,000,000 meters (109 times that of the Earth).

Its estimated 1.4 milion kilometers. However its constantly changing due to its mass loss to the Universe.
