The solar system has a new most-distant member, bringing its outer frontier into focus.
New work from Carnegie’s Scott Sheppard and Chadwick Trujillo of the Gemini Observatory reports the discovery of a distant dwarf planet, called 2012 VP113, which was found beyond the known edge of the solar system. This is likely one of thousands of distant objects that are thought to form the so-called inner Oort cloud. What’s more, their work indicates the potential presence of an enormous planet, perhaps up to 10 times the size of Earth, not yet seen, but possibly influencing the orbit of 2012 VP113, as well as other inner Oort cloud objects.
Aurora is a natural phenomenon occurring in the night sky around the Polar Regions, caused by atmospheric gases interacting with solar particles to create streamers, folds, or arches of colored light. On Earth, these are northern or southern lights. However, auroras are not only the beautiful part of Earth in our solar system. They are also found on Saturn, i.e. 6th planet of our solar system.
