The New Horizons spacecraft is racing toward an encounter with the most-distant object ever visited by humans. Ultima Thule is a member of the Kuiper Belt, a collection of icy, rocky bodies at the edge of our planetary system, well beyond the orbit of the most distant planet, Neptune. New Horizons made history in 2015, when it became the first spacecraft to visit Pluto. The encounter will occur on New Year’s Day.Read More New Horizons Races Toward Encounter with Ultima Thule — Most Distant World Ever Studied
Astronomers have found the most distant dwarf planet in our Solar System yet discovered. Known as VG18, this distant world is being called Farout by astronomers, due to it great distance from the Sun, roughly 120 times further away from our parent star as the Earth. Observations reveal this body, roughly 500 kilometers (or 300 miles) in diameter, has a pink surface, suggesting the world is covered in ice. Astronomers in Hawaii discovered the world while searching for a ninth planet, which some astronomers believe waits to be found in the far reaches of the Solar System.Read More Farout!
