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.

Hit-and-run heist of water by terrestrial planets...
on September 19, 2018 at 12:15 pm
A study simulating the final stages of terrestrial planet formation shows that 'hit-and-run' encounters play a significant role in the acquisition of water by large protoplanets, like those that grew into Mars and Earth. The results will be presented by Christoph Burger at the European Planetary Science Congress (EPSC) 2018 in Berlin. […]

For some time, scientists have known that Mars was once a much warmer and wetter environment than it is today. However, between 4.2 and 3.7 billion years ago, its atmosphere was slowly stripped away, which turned the surface into the cold and desiccated place we know today. Even after multiple missions have confirmed the presence of ancient lake beds and rivers, there are still unanswered questions about how much water Mars once had. […]
