The article published in Science provides information on the development, geology and composition of "planetesimane". As NASA said earlier, Ultima Thule has two columns that make it look like a snowman, although it really is like a pancake. It seems that these two clusters were formed close to each other until they became a pair of orbit, which eventually merged. The larger clove is about 22 x 20 x 7 km and the smaller is about 1
Ultima Thule is also very red. It's much milder than even Pluto and is actually the smallest object of New Horizons. While the team is still 100 percent. It is not convinced that redness is the result of modification of the organic matter on its surface. The article also notes that the object rotates on an axis every 15.92 hours and that its most prominent regions are on the neck side where clusters are connected. It has two bright spots in the biggest crater, as well
In the case of craters, Ultima Thule doesn't have many small ones, which shows that there are not many objects smaller than 1 km (~ 3000 feet) in diameter Kuiper belt. The article also states that New Horizons has not found any satellites, rings or surrounding circumstances. These are just the initial data from the flyby – in the coming months, we must learn more about the flat-rate snowman. The new Horizons probe still transmits data from the event and will do so by 2020. Summer.
