Kilometer


A kilometer (km) is a unit of length in the metric system, used to measure long distances. One kilometer equals 1,000 meters or about 0.62 miles. Kilometers are commonly used to measure distances between cities, in road signs, and in running or walking events. For example, a marathon is 42.195 kilometers long. The symbol for kilometer is "km". Most countries around the world use kilometers instead of miles for speed and distance, especially in transportation. Because it covers a large distance, the kilometer is not used for measuring small objects but is perfect for travel and mapping.


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.
