2015 KH162
orbits the Sun at a distance of 41.6–83.0 AU once every 491 years and 6 months (179,531 days). Its orbit has an eccentricity of 0.33 and an inclination of 29° with respect to the ecliptic . DISCOVERYIt was first observed on 18 May 2015, in the constellation of Serpens by astronomers at the Mauna Kea Observatories using the Subaru telescope . The discovery was announced by Scott Sheppard , David Tholen and C. Trujillo on 23 February 2016. At the time, this minor planet was at a distance of 59.0 AU from the Sun and had a relatively bright magnitude of 21.4 for its enormous distance

Magnitude (astronomy)
In astronomy , MAGNITUDE is a logarithmic measure of the brightness of an object , measured in a specific wavelength or passband , usually in the visible or near-infrared spectrum. An imprecise but systematic determination of the magnitude of objects was introduced in ancient times by Hipparchus
Hipparchus
. Astronomers use two different definitions of magnitude: apparent magnitude and absolute magnitude. The apparent magnitude (m, or vmag for the visible spectrum) is the brightness of an object as it appears in the night sky from Earth, while the absolute magnitude (Mv, V and H) describes the intrinsic brightness of an object as it would appear if it were placed at a certain distance from Earth. This distance is 10 parsecs for stars and 1 astronomical unit for planets and small Solar System
Solar System
bodies . A minor planet 's size is typically estimated based on its absolute magnitude in combination with its presumed albedo

Minor Planet
A MINOR PLANET is an astronomical object in direct orbit around the Sun
Sun
that is neither a planet nor exclusively classified as a comet . Minor planets can be dwarf planets , asteroids , trojans , centaurs , Kuiper belt
Kuiper belt
objects, and other trans-Neptunian objects . As of 2017, the orbits of 734,274 minor planets were archived at the Minor Planet Center , 496,815 of which had received permanent numbers (for the complete list , see index ). The first minor planet to be discovered was Ceres in 1801. The term minor planet has been used since the 19th century to describe these objects. The term PLANETOID has also been used, especially for larger (planetary) objects such as those the International Astronomical Union (IAU) has called dwarf planets since 2006. Historically, the terms asteroid, minor planet, and planetoid have been more or less synonymous

Small Solar System Body
A SMALL SOLAR SYSTEM BODY (SSSB) is an object in the Solar System that is neither a planet , nor a dwarf planet , nor a natural satellite . The term was first defined in 2006 by the International Astronomical Union . All other objects, except satellites, orbiting the Sun
Sun
shall be referred to collectively as "Small Solar System

Bodies" ... These currently include most of the Solar System

asteroids, most Trans-Neptunian Objects (TNOs), comets, and other small bodies. This encompasses all comets and all minor planets other than those that are dwarf planets . Thus SSSBs are: the classical asteroids with the exception of the dwarf planet Ceres ; the trojans ; and the centaurs and trans-Neptunian objects with the exception of Pluto

Serpens
SERPENS ("the Serpent", Greek Ὄφις) is a constellation of the northern hemisphere . One of the 48 constellations listed by the 2nd-century astronomer Ptolemy
Ptolemy
, it remains one of the 88 modern constellations defined by the International Astronomical Union
International Astronomical Union
. It is unique among the modern constellations in being split into two non-contiguous parts, SERPENS CAPUT (Serpent Head) to the west and SERPENS CAUDA (Serpent Tail) to the east. Between these two halves lies the constellation of Ophiuchus

Apparent Magnitude
The APPARENT MAGNITUDE (M) of a celestial object is a number that is a measure of its brightness as seen by an observer on Earth. The brighter an object appears, the lower its magnitude value (i.e. inverse relation). The Sun, at apparent magnitude of −27, is the brightest object in the sky. It is adjusted to the value it would have in the absence of the atmosphere . Furthermore, the magnitude scale is logarithmic ; a difference of one in magnitude corresponds to a change in brightness by a factor of 5√100, or about 2.512. The measurement of apparent magnitudes or brightnesses of celestial objects is known as photometry . Apparent magnitudes are used to quantify the brightness of sources at ultraviolet , visible , and infrared wavelengths. An apparent magnitude is usually measured in a specific passband corresponding to some photometric system such as the UBV system

Scattered Disc
The SCATTERED DISC (or SCATTERED DISK) is a distant circumstellar disc in the Solar System
Solar System
that is sparsely populated by icy minor planets , a subset of the broader family of trans-Neptunian objects . The scattered-disc objects (SDOs) have orbital eccentricities ranging as high as 0.8, inclinations as high as 40°, and perihelia greater than 30 astronomical units (4.5×109 km; 2.8×109 mi). These extreme orbits are thought to be the result of gravitational "scattering" by the gas giants , and the objects continue to be subject to perturbation by the planet Neptune
Neptune
. Although the closest scattered-disc objects approach the Sun
Sun
at about 30–35 AU , their orbits can extend well beyond 100 AU. This makes scattered objects among the most distant and coldest objects in the Solar System

Ecliptic
The ECLIPTIC is the circular path on the celestial sphere that the Sun
Sun
appears to follow over the course of a year ; it is the basis of the ecliptic coordinate system . The term also refers to the plane of this path, which is coplanar with Earth\'s orbit around the Sun
Sun
(and hence the Sun's apparent orbit around Earth
Earth
). The ecliptic is not normally noticeable from Earth's surface because Earth

List Of Minor-planet Groups
A MINOR-PLANET GROUP is a population of minor planets that share broadly similar orbits. Members are generally unrelated to each other, unlike in an asteroid family , which often results from the break-up of a single asteroid. It is customary to name a group of asteroids after the first member of that group to be discovered, which is often the largest

List Of Minor Planets
This is a list of numbered minor planets in the Solar System, in numerical order. As of July 2017 there are 496,815 numbered minor planets, and 237,441 unnumbered . Only 21,009 or approximately 4% of all numbered minor planets are currently named , mostly for people and figures from mythology and fiction . The Jupiter trojan (3708) 1974 FV1 is currently the lowest-numbered unnamed minor planet. Minor planets also include dwarf planets of which 5 have been officially recognized by the IAU with potentially hundreds more to follow in the future

Near-Earth Object

Solar System
body whose orbit brings it into proximity with Earth
Earth
. By definition, a solar system body is a NEO if its closest approach to the Sun
Sun
(perihelion ) is less than 1.3 astronomical unit (AU). NEOs include more than fourteen thousand near- Earth
Earth
asteroids (NEAs), more than one hundred near-Earth comets (NECs), and a number of solar-orbiting spacecraft and meteoroids , large enough to be tracked in space before striking the Earth. It is now widely accepted that collisions in the past have had a significant role in shaping the geological and biological history of the Earth. NEOs have become of increased interest since the 1980s because of increased awareness of the potential danger some of the asteroids or comets pose, and mitigations are being researched

Jupiter Trojan
The JUPITER TROJANS, commonly called TROJAN ASTEROIDS or just TROJANS, are a large group of asteroids that share the planet Jupiter 's orbit around the Sun
Sun
. They are named for heroes in the ancient Greek tales of the Trojan War . Relative to Jupiter, each Trojan librates around one of Jupiter's two stable Lagrange points : L4, lying 60° ahead of the planet in its orbit, and L5, 60° behind. Jupiter
Jupiter
trojans are distributed in two elongated, curved regions around these Lagrangian points with an average semi-major axis of about 5.2 AU. If you draw a line from Jupiter
Jupiter
to each group of asteroids (one group that follows Jupiter
Jupiter
in its orbit, and others that move ahead of it in its orbit), and then draw lines from Jupiter and both groups to the Sun, you will have two equal-sided triangles
