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.

Warped space-time to help WFIRST find exoplanets
on March 31, 2020 at 1:51 pm
NASA's Wide Field Infrared Survey Telescope (WFIRST) will search for planets outside our solar system toward the center of our Milky Way galaxy, where most stars are. Studying the properties of exoplanet worlds will help us understand what planetary systems throughout the galaxy are like and how planets form and evolve.

The hypothesis that the solar system originated from a gigantic cloud of gas and dust was first floated in the second half of the 18th century by German philosopher Immanuel Kant and further developed by French mathematician Pierre-Simon de Laplace. It is now a consensus among astronomers. Thanks to the enormous amount of observational data, theoretical input and computational resources now available, it has been continually refined, but this is not a linear process.
Supermassive black holes shortly after the Big...

They are billions of times larger than our Sun: how is it possible that, as recently observed, supermassive black holes were already present when the Universe, now 14 billion years old, was "just" 800 million years old? For astrophysicists, the formation of these cosmic monsters in such a short time is a real scientific headache, which raises important questions on the current knowledge of the development of these celestial bodies.
Asteroid Ryugu likely link in planetary formation
on March 17, 2020 at 2:12 pm
The solar system formed approximately 4.5 billion years ago. Numerous fragments that bear witness to this early era orbit the sun as asteroids. Around three-quarters of these are carbon-rich C-type asteroids, such as 162173 Ryugu, which was the target of the Japanese Hayabusa2 mission in 2018 and 2019. The spacecraft is currently on its return flight to Earth. Many scientists, including planetary researchers from the German Aerospace Center (Deutsches Zentrum für Luft-und Raumfahrt; DLR), […]
How the moon formed: New research sheds light on...
on March 10, 2020 at 12:45 pm
How the Earth got its moon is a long debated question. The giant impact theory – which states that the moon formed from the a collision between the early Earth and a rocky body called Theia—has become the front runner among the explanations. But the details around how this happened are blurry and there are many observations that scientists are still struggling to explain.
