Attometer

An attometer (am) is a unit of length in the metric system, equal to one-quintillionth of a meter (1 am = 10⁻¹⁸ meters). This unit is extremely small, even smaller than a femtometer, and is used in theoretical physics to describe distances at the quantum level, such as within particles or in advanced models of spacetime. However, attometers are rarely used in practice because most known physical structures, including subatomic particles, are still larger than this. The attometer mainly appears in scientific equations or hypotheses dealing with concepts beyond current experimental capabilities.

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.
