Now we are going to do measurement of radius of Proxima Centauri. which is 3.3 times large from the sun. So for measurement of radius, we shall use simple law. which I had written some year ago.
About Law of Radius.
before the measurement, you should understand Law of measurement. that the radius is first basic step for measurement of diameter of star. or we cannot direct measurement of diameter before the radius. So radius is first basic process of measurement.
First Law of Radius.
Here “R” is basic radius of object. or “R” is equal to tool of measurement. So “R” is a Tool of measurement. such as we use the meter for measurement to a thing.
Value of “R”
Here “R” value is 6959900000 km. which is fix for measurement of all stars. and this value belongs with radius of sun. Therefore, Sun = “R”6959900000 km radius.
Second Law of Radius.
Here “S”1 is equal to 1-Time-year. such as sun last boundary is equal to 1-Time-year. therefore it will be called the “S”1, So {(”R” x “S”1)= radius of sun} and it is complete Law of measurement.
Sun`s Radius.
Here sun`s radius is (”R” x “S”1). because “R”6959900000 km x “S”1 = 6959900000 km radius of sun.
Radius for Proxima Centauri.
Here (”R” x “S”3.3)= radius of Proxima Centauri. for kilometers. “R”6959900000 x “S”3.3 = 2.2967670000 kilometers radius of Proxima Centauri. and this radius is 3.3 times large from the sun.
Seconds of radius.
we are making seconds of the radius of Proxima Centuri. 2.2967670000 / 300,000 light speed = 76558.9 seconds of radius. and this distance is 3.6 percent large from distance of Jupiter from the sun.
By a Imagine.
If you want Imagine about radius of Proxima Centauri. that It is very easy matter. because you can see to the sun and Jupiter through the natural eyes. So Jupiter distance is 20820 light seconds from the sun.
and Sun radius is 6959900000 kilometers. now for seconds 6959900000 / 300,000 light seepd = 23199.66 seconds radius of Sun. and this radius is some percent large fron the distance of Jupiter. or 23199.66 - 20820 = 2379.66 seconds,
So Sun is 2379.66 extra large from the distance of Jupiter. So you can Imagine this distance in the brain. Now Proxima Centauri seconds are 76558.9 and Jupiter seconds are 20820. therefore 76558.9 / 20820 = 3.67 percent large radius of Proxima Centauri.
