Kuiper Belt are presumed to be remnants from the formation of the solar system about 4.6 billion years ago. The Kuiper Belt extends from about 30 to 55 AU and is prob-ably populated with hundreds of thousands of icy bodies larger than 100 kilometers (62 miles) across and an estimated trillion or more comets.
In Depth | Kuiper Belt – NASA Solar System Exploration
The Kuiper Belt represents an enormous, donut-shaped volume of space in the outer solar system. While there are many icy bodies in this region that we broadly refer to as Kuiper Belt Objects (KBOs) or trans-Neptunian objects (TNOs), they're fairly diverse in size, shape, and color.
Gravity Assist: The Kuiper Belt with Alan Stern
2018年1月31日 · In this episode of Gravity Assist, Jim Green talks with New Horizons Principal Investigator Alan Stern about what we’ve learned about Kuiper Belt object 2014 MU69 and the remarkable story of how -- against all odds -- the New Horizons team captured MU69’s fleeting shadow on Earth as the object passed in front of a distant star.
New Horizons Successfully Explores Ultima Thule
2019年1月1日 · NASA's New Horizons spacecraft flew past Ultima Thule in the early hours of New Year's Day, ushering in the era of exploration from the enigmatic Kuiper Belt, a region of primordial objects that holds keys to understanding the origins of the solar system.
Hubble to Conduct Largest-Ever Survey of Kuiper Belt
2019年4月2日 · At the present time, the properties of the Kuiper Belt’s unique population of binary systems can only be accurately measured with Hubble. SwRI leads this large HST project focused on characterizing the binary and color properties of over 200 unique KBOs.
New Horizons Spacecraft Homing in on Kuiper Belt Target
2018年12月31日 · After a 13-year journey, the piano-sized spacecraft has covered a distance of four billion miles to reach Ultima Thule in the Kuiper Belt — a donut-shaped region of ancient, rocky bodies beyond the orbit of Neptune.
In Depth | Haumea – NASA Solar System Exploration
Dwarf planet Haumea is a member of a group of objects that orbit in a disc-like zone beyond the orbit of Neptune called the Kuiper Belt. This distant realm is populated with thousands of miniature icy worlds which formed early in the history of our solar system about 4.5 billion years ago.
In Depth | Pluto – NASA Solar System Exploration
Dwarf planet Pluto is a member of a group of objects that orbit in a disc-like zone beyond the orbit of Neptune called the Kuiper Belt. This distant realm is populated with thousands of miniature icy worlds, which formed early in the history of our solar system about 4.5 billion years ago.
The Exploration of Neptune and Triton
Neptune and its captured moon Triton are unexplored with modern spacecraft instrumentation. Observations of these objects are urgently needed to address planet formation and the evolution of ice giant planets, icy satellites, Kuiper Belt Objects, and the solar system itself.
