Home As the top of the chart shows, three asteroids of different sizes can look similar when viewed in visible-light. The bottom half of the chart illustrates what an infrared telescope would see when viewing the same three asteroids. Because infrared detectors sense the heat of an object, which is more directly related to its size, the larger rock appears brighter.
