Feb 28, 2019 · This workshop brings together experts to establish the current understanding of Main Belt asteroid science, as well as to debate future directions for investigation. The workshop stimulates discussions about accretion, chemistry, collisions, dynamics, geophysics, and meteorites. The workshop is limited to approximately 100 attendees. Main ...
The torpedo belt was part of the armoring scheme in some warships between the 1920s and 1940s. It consisted of a series of lightly armored compartments, extending laterally along a narrow belt that intersected the ship's waterline. In theory this belt would absorb the explosions from torpedoes, or any naval artillery shells that struck below ...
Asteroids, including those in the asteroid belt, have been suggested as possible sites of space colonization. [1] Motives include the survival of humanity, and the specific economic opportunity for asteroid mining. Obstacles include transportation distance, temperature, radiation, lack of gravity, and psychological issues.
Belt armor is a layer of heavy metal armor plated onto or within the outer hulls of warships, typically on battleships, battlecruisers and cruisers, and aircraft carriers . The belt armor is designed to prevent projectiles from penetrating to the heart of a warship. When struck by an artillery shell or underwater torpedo, the belt armor either ...
Jan 18, 2008 · The main belt region is shown in red, and contains 93.4% of all the objects. For reference, Mars orbits out to 1.666 AU, and Jupiter between 4.95 and 5.46 AU. The diagram was created by Piotr Deuar [1] using orbit data for 120437 numbered minor planets from the Minor Planet Center orbit database, dated 8 Feb 2006.
Jan 1, 2014 · The P asteroids peak at about 4 AU, and the D asteroids at 5.2 AU; they are probably richer in low-temperature materials such as carbon compounds, complex organics, clays, water, and volatiles and represent the transition between the rocky asteroids of the main belt and the volatile-rich comets in the Kuiper Belt and the Oort Cloud.
The Oort cloud ( / ɔːrt, ʊərt / ), [1] sometimes called the Öpik–Oort cloud, [2] is theorized to be a vast cloud of icy planetesimals surrounding the Sun at distances ranging from 2,000 to 200,000 AU (0.03 to 3.2 light-years ). [3] [note 1] [4] The concept of such a cloud was proposed in 1950 by the Dutch astronomer Jan Oort, in whose ...
