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.

Ångström

An ångström (symbol: Å) is a unit of length commonly used in physics, chemistry, and biology to measure very small distances, such as atomic and molecular scales. It is equal to 10⁻¹⁰ meters, or 0.1 nanometers (nm).

The unit is named after the Swedish physicist Anders Jonas Ångström, who made significant contributions to spectroscopy.

Key facts:

• 
  

  1 ångström = 10⁻¹⁰ meters = 0.1 nanometers

  
  
• 
  

  Used to measure atomic and molecular sizes, wavelengths of light, and crystal lattice constants

  
  
• 
  

  Common in fields like crystallography, chemistry, and materials science

  
  

Though largely replaced by the nanometer in the SI system, the ångström remains widely used in scientific literature to describe very small lengths.
