APOD 1.6

       This image is very interesting. I have always known that throughout the universe there are other objects than planets and stars, such as comets and asteroids. Typical knowledge that I have however leads me to believe that they are very scarse, such as Haley's comet. This image places gives me a better perspective of the actual amount of asteroids there are in such a close proximity to Earth. The word close, being used very vaguelly. Thanks to Neowise and their infared imaging, we have a better knowledge of the number of asteroids. As light is a difficult determinant to exactly calculate the number of asteroids. Some asteroids are non-reflective and others are extremely reflective. The suns heat is stored in the asteroid, allowing infared radars to detect the presence of an asteroid.
