It orbits very close to the Sun, having the eighth smallest semi-major axis of any minor planet in the Solar System. At its closest, it is only 0.26 AU km mi on on from the Sun, but more than 100 minor planets have a smaller perihelion distance. Despite being officially classified as a near-Earth object, 2013 JX 28 has a MOID (minimum orbit intersection distance) with Earth of ~0.067 AU, making it highly unlikely to ever hit Earth. For comparison, the Moon orbits Earth at about 1/26th this distance. Physical characteristics 2013 JX 28 has an absolute magnitude (H) of 20.1, which means it is rather small, with the size being approximately 300 meters based on an assumed albedo of 0.15. Its albedo is not known, so a size estimate is not certain. Assuming the albedo is between 0.05 and 0.25, it is somewhere between 260–580 meters in diameter.Absolute Magnitude (H) NASA/JPL http://neo.jpl.nasa.gov/glossary/h.html https://web.archive.org/web/20010302182040/http://neo.jpl.nasa.gov/glossary/h.html dead 2001-03-02 2014-02-15 163693 Atira, an asteroid with an orbit similar to 2013 JX 28, for comparison, has an absolute magnitude of 16.28 and is notably larger. Close approaches As a near-Earth object, 2013 JX 28 often comes within 0.1 AU km mi on off] of Earth. On 29 April 2014, it traveled to 0.0843 AU from Earth, about 33 times further than the Moon. Below is a list of close approaches until 2100 where 2013 JX 28 travels closer than 0.1 AU to Earth. date distance (AU) 2000-04-20 0.0913 2007-04-25 0.0682 2014-04-29 0.0843 2034-04-21 0.0888 2041-04-25 0.0680 2048-04-29 0.0849 2068-04-21 0.0863 2075-04-26 0.0676 2082-04-30 0.0890 References External links 2013 JX28 2013 JX28 # Category:Minor planet object articles (unnumbered) 20060525 20130511
