'''{{mp|2013 MZ|5}}''' is an [[asteroid]] discovered in 2013 with the [[Pan-STARRS]] telescope. It is classified as a [[Near-Earth Object]] and happens to be the 10,000th one ever discovered.<ref>[http://www.jpl.nasa.gov/news/news.php?release=2013-207 Ten Thousandth Near-Earth Object Unearthed in Space] jpl.nasa.gov</ref> |
|||
'''{{mp|(511002) 2013 MZ|5}} ''', provisional designation {{mp|2013 MZ|5}}, is a sub-kilometer [[asteroid]], classified as a [[near-Earth object]] of the [[Amor asteroid|Amor group]], estimated to measure approximately {{convert|300|m|ft|abbr=off|sigfig=1|sp=us}} in diameter. It was discovered on 18 June 2013, by astronomers with the [[Pan-STARRS]] survey at [[Haleakala Observatory]] on the island of Maui, Hawaii, in the United States.<ref name="MPC-object" /> It was the 10,000th near-Earth object ever discovered.<ref name="NASA-news" /> |
|||
This asteroid is approximately 1,000 feet (300 meters) across. Its orbit is well understood and will not approach close enough to Earth to be considered potentially hazardous. |
|||
== Orbit and classification == |
|||
==References== |
|||
{{mp|2013 MZ|5}} is an [[Amor asteroid]] – a subgroup of near-Earth asteroids that approach the orbit of Earth from beyond, but do not cross it. It orbits the Sun at a distance of 1.3–1.8 [[Astronomical unit|AU]] once every 23 months (707 days; [[semi-major axis]] of 1.55 AU). Its orbit has an [[orbital eccentricity|eccentricity]] of 0.18 and an [[orbital inclination|inclination]] of 29[[Degree (angle)|°]] with respect to the [[ecliptic]].<ref name="jpldata" /> The body's [[observation arc]] begins with its official discovery observation at Haleakala in June 2013.<ref name="MPC-object" /> |

|||
The asteroid has an Earth [[minimum orbital intersection distance]] of {{convert |0.4613 |AU |km |abbr=on |lk=off |sigfig=3 |order=flip}}, which translates into 180 [[Lunar distance (astronomy)|lunar distances]]. It also makes close approaches to Mars. On 28 August 2125, it is projected to pass the Red Planet at a nominal distance of {{convert |0.0910 |AU |km |abbr=on |lk=off |sigfig=3 |order=flip}}. With an [[aphelion]] of 1.83 AU, it is also a [[Mars-crossing asteroid]].<ref name="jpldata" /> |

== 10,000th discovered NEO == |
|||
{{mp|2013 MZ|5}} was the 10,000th [[near-Earth object]] (NEO) ever discovered in June 2013 and considered a significant milestone in exploring the NEO population.<ref name="NASA-news" /> |
|||
== Numbering and naming == |
|||
This [[minor planet]] was [[Minor planet designation|numbered]] by the [[Minor Planet Center]] on 31 January 2018 and received the number {{LoMP|511002|511002}} in the [[LOMP|minor planet catalog]] ({{small|[[Minor Planet Circulars|M.P.C.]] 108621}}).<ref name="MPC-Circulars-Archive" /> As of 2019, it has not been [[List of named minor planets (numerical)|named]].<ref name="MPC-object" /> |
|||
== Physical characteristics == |
|||
=== Diameter and albedo === |
|||
{{mp|2013 MZ|5}} measures approximately 300 meters in diameter for an [[absolute magnitude]] of 20.1 and an assumed [[Astronomical albedo|albedo]] 0.18, which is typical value for [[S-type asteroid|stony asteroids]].<ref name="h" /><ref name="NASA-news" /> A generic magnitude-to-diameter conversion on a wider range of possible albedos (0.30 to 0.05) gives a diameter between 230 and 570 meters.<ref name="h" /> As of 2019, no rotational [[lightcurve]] of {{mp|2013 MZ|5}} has been obtained from [[Photometry (astronomy)|photometric]] observations. The object's effective size, [[rotation period]], [[Poles of astronomical bodies|pole]] and shape remain unknown.<ref name="jpldata" /><ref name="lcdb" /> |
