Femtometer

A femtometer (fm) is a unit of length in the metric system, equal to one-quadrillionth of a meter (1 fm = 10⁻¹⁵ meters). It is also known as a fermi, named after the physicist Enrico Fermi. Femtometers are used to measure extremely small distances at the subatomic level, such as the size of protons, neutrons, and atomic nuclei. For example, the radius of a proton is about 0.84 femtometers. This unit is commonly used in nuclear physics and particle physics, but it's far too small for everyday measurements.

Earth’s Distance from the Sun

The average distance between the Earth and the Sun is known as an Astronomical Unit (AU).

• 
  

  It is approximately 149.6 million kilometers (about 93 million miles).

  
  
• 
  

  This distance varies slightly throughout the year because Earth’s orbit is elliptical—closest at perihelion (~147.1 million km) and farthest at aphelion (~152.1 million km).

  
  
• 
  

  The astronomical unit is a fundamental standard for measuring distances within our solar system.

  
  

Key facts:

• 
  

  Average distance ≈ 149.6 million km (1 AU)

  
  
• 
  

  Varies due to elliptical orbit

  
  
• 
  

  Basis for measuring planetary distances

  
  

Understanding Earth’s distance from the Sun is essential for studying seasons, climate, and orbital mechanics.
