Sun’s Radius

The radius of the Sun is the distance from its center to its surface (photosphere).

• 
  

  It is approximately 696,340 kilometers (about 432,685 miles).

  
  
• 
  

  The Sun is a nearly perfect sphere of hot plasma, and this radius defines its visible "surface."

  
  
• 
  

  The Sun’s radius is about 109 times the radius of Earth.

  
  

Key facts:

• 
  

  Sun’s radius ≈ 696,340 km

  
  
• 
  

  Defines the size of the Sun’s visible surface

  
  
• 
  

  Critical for understanding solar structure and scale

  
  

Knowing the Sun’s radius helps astronomers model solar phenomena and compare the Sun with other stars.

Russian Archin

The archin (also spelled arshin) is a traditional Russian unit of length that was widely used before the adoption of the metric system. It is approximately equal to 28 inches or 0.7112 meters.

The archin was commonly used in measuring cloth, land, and building dimensions in Russia and neighboring regions. It roughly corresponds to the length of a forearm from the elbow to the tip of the middle finger, similar to the cubit.

Though obsolete today, the archin remains an important part of Russian historical measurements and appears in older legal and trade documents.
