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.

Fathom

A fathom is a unit of length traditionally used to measure the depth of water. It equals 6 feet or approximately 1.8288 meters.

Originating from the Old English word fæðm, meaning "to embrace" or "outstretched arms," the fathom was based on the average distance between a person's outstretched arms. It has been widely used by sailors and navigators to estimate sea depths and underwater distances.

Key facts:

• 
  

  1 fathom = 6 feet

  
  
• 
  

  1 fathom ≈ 1.8288 meters

  
  
• 
  

  1 fathom = 2 yards

  
  

Though modern sonar and electronic instruments now measure depth more precisely, the fathom remains a traditional unit in nautical contexts, especially in maritime charts and historical references.
