Operation Rahu Episode XI "How far is the sun"
Partial Solar Eclipse 26 December 2019
Question: we know from Google that Earth - Sun distancce is about 149,597,870 Km, How can you proof it by yourself?
Answer: Yes no problem, with the help of modernized digital technology plus the ancient Greek Mathematics I can easily calculate distance Earth - Sun after obtaining a clear photo of partial solar eclipce
Step 1 Get "Earth's diameter" from the Operation Eratosthenes I 21 Mar 2012 and Operation Eratosthenes II 21 Mar 2019 and here we have Earth's circumference = 38,451 Km and Earth's diameter = 12,234 Km (QR Code)
Operation Eratosthenes Episode I 21 March 2012
Operation Eratosthenes Episode II 21 March 2019
Step 2 Referring to Operation Rahu Episode VIII (QR Code) we got distance Earth - Moon = 355,529 Km
Step 3 Operation Rahu Episode XI how far is the sun
Since we have got Earth's diameter and distance Earth - Moon, the next move is waiting for some nice photos of partial solar eclipse on 26 Dec 2019 from "facebook friends"
Total solar eclipse will be observed in Singapore but at the higher latitide toward north like Bangkok it will be partial solar eclipse
The solar eclipse 26 Dec 2019 is hapenning in the sametime of an astronomical phenomena called "winter solstice" (the ancient Khmer solar calendar at Prasat Phupek Sakon Nakhon is showing sunrise at the southern most of horizon)
Here comes 4 nice photos of partial solar eclipse from my facebook friends (the red color photos are from Thai Professional Tour Guide Khun Pom Dararat in Chiangmai and the orange color photo is taken at Sakonraj Wittayanukool School by a science teacher named MS Chol Cholruecha)
Rule of Angular Diameter
With the help of PowerPoint program try to matching "size of moon and size of the sun" are they the same?, yes they are exactly the same. According to the rule of angular diameter; distance from Earth - Sun is 400 times of distance Earth - Moon
Size of the moon is exactly the same as the sun
Apply the rule of angular diameter
Distance Earth - Sun = 142,211,600 Km with only 5% error
