Small Solar System Body (SSSB) is an object in the Solar System that is neither a planet, a dwarf planet, nor a natural satellite. The term was first defined in 2006 by the International Astronomical Union (IAU). This encompasses all comets and all minor planets other than those that are dwarf planets. Thus SSSBs are: the comets; the classical asteroids, with the exception of the dwarf planet Ceres; the trojans; and the centaurs and trans-Neptunian objects, with the exception of the dwarf planets Pluto, Haumea, Makemake, and Eris and others that may turn out to be dwarf planets. — Wikipedia
Minor Planet is an astronomical object in direct orbit around the Sun (or more broadly, any star with a planetary system) that is neither a planet nor exclusively classified as a comet. Before 2006, the International Astronomical Union (IAU) officially used the term minor planet, but during that year’s meeting it reclassified minor planets and comets into dwarf planets and small Solar System bodies (SSSBs). Minor planets include asteroids (near-Earth objects, Mars-crossers, main-belt asteroids and Jupiter trojans), as well as distant minor planets (centaurs and trans-Neptunian objects), most of which reside in the Kuiper belt and the scattered disc. — Wikipedia

- Space Rocks! - NASA engineers had quite a New Years celebration in 2019 when New Horizons successfully executed a flyby of a tiny object named 2014 MU69 while moving at 32,000 miles per hour. The planetesimal 2014 MU69 is better known by it’s nickname Ultima Thule, and it’s located way out past Pluto in a region of the … Continue reading Space Rocks!

NASA’s Eyes is a freely available suite of computer visualization applications created by the Visualization Technology Applications and Development Team at NASA’s Jet Propulsion Laboratory (JPL) to render scientifically accurate views of the planets studied by JPL missions and the spacecraft used in that study. Eyes on Astroids provides real-time visualization of every known asteroid or coment that is classified as a Near-Earth Object (NEO). You can also explore most of NASA’s asteroid and comet missions (past and present), from Galileo , to Lucy and DART.– Wikipedia

A Jupiter-sized world just 7.5 light-years away is cloudy, chemically complex and, it turns out, more like home than anyone expected. Using the James Webb Space Telescope, Brittany Miles, assistant astronomer at the University of Arizona's Steward Observatory, led a team that spent 11 hours staring at WISE 0855, the coldest known brown dwarf, collecting a spectrum of its light every 15 minutes.

A nearby star system with two suns could potentially support an Earth-sized planet in a region where liquid water could exist, according to a new paper examining the dynamics of the system.

In the early history of our solar system, scientists theorize that a Mars-sized object called Theia smashed into the infant Earth, vaporizing massive amounts of rock and blasting it into space. Some of that material coalesced into the moon, where NASA's Artemis program is returning humans, preparing for Mars and shaping the future of space exploration.
