Solar System Exploration: Small Body (NASA)


Small Solar System body (SSSB) is an object in the Solar System that is neither a planet, nor a dwarf planet, nor a natural satellite. The term was first defined in 2006 by the International Astronomical Union (IAU).

All other objects, except satellites, orbiting the Sun shall be referred to collectively as “Small Solar System Bodies” … These currently include most of the Solar System asteroids, most Trans-Neptunian Objects (TNOs), comets, and other small bodies.

    • Image: Jupiter-family comet 46P Wirtanen
      on January 18, 2019 at 12:21 pm

      The ghostly green glow at the very top of this image reveals the presence of 46P Wirtanen – a relatively small comet with an estimated diameter of 1.2 kilometers. Had the path of history taken a different course, we would have much more than estimates about this Jupiter-family comet. […]

      on January 16, 2019 at 6:00 pm

      Columbia University scientists, in collaboration with researchers from Harvard, have succeeded in developing a chemical process to absorb infrared light and re-emit it as visible energy, allowing innocuous radiation to penetrate living tissue and other materials without the damage caused by high-intensity light exposure. […]

      On October 19th, 2017, the Panoramic Survey Telescope and Rapid Response System-1 (Pan-STARRS-1) in Hawaii announced the first-ever detection of an interstellar object, named 1I/2017 U1 (aka. 'Oumuamua). In the months that followed, multiple follow-up observations were conducted to learn more about this visitor, as well as resolve the dispute about whether it was a comet and an asteroid.
