(307261) 2002 MS 4 (provisional designation 2002 MS 4) is a large trans-Neptunian object in the Kuiper belt, which is a region of icy planetesimals beyond Neptune.It was discovered on 18 June 2002 by Chad Trujillo and Michael Brown during their search for bright, Pluto-sized Kuiper belt objects at Palomar Observatory.
The Kuiper belt is a ring of small icy worlds, similar to the asteroid belt but far larger, extending from Neptune's orbit at 30 AU out to about 55 AU from the Sun. [145] Much in the same way that Jupiter's gravity dominates the asteroid belt, Neptune's gravity dominates the Kuiper belt. Over the age of the Solar System, certain regions of the ...
Urbain Jean Joseph Le Verrier (French: [yʁbɛ̃ ʒɑ̃ ʒozɛf lə vɛʁje]; 11 March 1811 – 23 September 1877) was a French astronomer and mathematician who specialized in celestial mechanics and is best known for predicting the existence and position of Neptune using only mathematics.
These irregularities could, however, be resolved if the gravity of a farther, unknown planet were disturbing its path around the Sun. In 1845, astronomers Urbain Le Verrier in Paris and John Couch Adams in Cambridge separately began calculations to determine the nature and position of such a planet.
The Imaging Science Subsystem made up of a wide-angle and a narrow-angle camera is a modified version of the slow scan vidicon camera designs that were used in the earlier Mariner flights. The Imaging Science Subsystem consists of two television-type cameras, each with eight filters in a commandable filter wheel mounted in front of the vidicons.
Neptune's rings had been observed from Earth many years prior to Voyager 2 's visit, but the close inspection revealed that the ring systems were full circle and intact, and a total of four rings were counted. [4] Voyager 2 discovered six new small moons orbiting Neptune's equatorial plane, dubbed Naiad, Thalassa, Despina, Galatea, Larissa and ...
Rings of Neptune imaged by the James Webb Space Telescope's NIRCam instrument. The rings of Neptune consist primarily of five principal rings.They were first discovered (as "arcs") by simultaneous observations of a stellar occultation on 22 July 1984 by André Brahic's and William B. Hubbard's teams at La Silla Observatory (ESO) and at Cerro Tololo Interamerican Observatory in Chile. [1]
New Horizons may also take a picture of Earth from its distance in the Kuiper belt, but only after completing all planned KBO flybys and imaging Uranus and Neptune. [223] [224] This is because pointing a camera towards Earth could cause the camera to be damaged by sunlight, [225] as none of New Horizons' cameras have an active shutter mechanism ...
