(208996) 2003 AZ84

1. 본문

(208996) 2003 AZ84 is a trans-Neptunian object and a plutino, meaning it orbits in a 2:3 resonance with Neptune, similar to Pluto. It's located in the outer regions of the Solar System, specifically within the Kuiper Belt.

Here's a breakdown of its key characteristics:

• Size and Shape: It has an elongated shape, with its longest axis measuring approximately 940 kilometers. Estimates of its diameter vary, with measurements ranging from roughly 468 to over 900 km.
• Potential Dwarf Planet: Due to its size, 2003 AZ84 is considered a possible dwarf planet.
• Orbit: It has a moderately eccentric orbit, inclined by about 13.6 degrees to the ecliptic. It orbits the Sun every 247.50 years (90,400 days), with its distance varying between 32.41 AU and 46.41 AU.
• Orbital Resonance: It is in a 2:3 orbital resonance with Neptune. This means that for every three orbits Neptune completes, 2003 AZ84 completes two.
• Discovery: It was discovered on January 13, 2003, by astronomers Chad Trujillo and Michael Brown during the NEAT survey at Palomar Observatory.
• Possible Moon: 2003 AZ84 has a possible moon.
• Rotation Period: There are different measurements on the rotation, one being approximately 13.42 hours.
• Surface Features: Stellar occultation data suggests a possible topographic feature, described as a chasm.
