Washington, DC — In the race to discover a proposed ninth planet in our Solar System, Carnegie’s Scott Sheppard and Chadwick Trujillo of Northern Arizona University have observed several never-before-seen objects at extreme distances from the Sun in our Solar System. Sheppard and Trujillo have now submitted their latest discoveries to the International Astronomical Union’s Minor Planet Center for official designations. A paper about the discoveries has also been accepted to The Astronomical Journal. (more…)

Washington, D.C.—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.

Washington, D.C.—There are places in space where the gravitational tug between a planet and the Sun balance out, allowing other smaller bodies to remain stable. These places are called Lagrangian points. So-called Trojan asteroids have been found in some of these stable spots near Jupiter and Neptune. Trojans share their planet’s orbit and help astronomers understand how the planets formed and how the solar system evolved.
