Key Facts

Overview

455502 (2003 UZ413) is a dwarf planet whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified 2003 UZ413 as potentially hazardous because its orbit does not bring it close to Earth.

2003 UZ413 orbits the sun every 89,600 days (245.31 years), coming as close as 30.31 AU and reaching as far as 48.05 AU from the sun. Based on its brightness and the way it reflects light, 2003 UZ413 is probably between 366.906 to 820.427 kilometers in diameter, making it one of the largest objects, very roughly comparable in size to Great Britain.

The rotation of 2003 UZ413 has been observed. It completes a rotation on its axis every 4.14 days.

No Close Approaches

2003 UZ413's orbit is 29.30 AU from Earth's orbit at its closest point. This means that there is an extremely wide berth between this asteroid and Earth at all times.

Orbital simulations conducted by NASA JPL's CNEOS do not show any close approaches to Earth.

Images and Observations

2003 UZ413's orbit is determined by observations dating back to July 29, 1954. It was last officially observed on Oct. 23, 2020. The IAU Minor Planet Center records 335 observations used to determine its orbit.

Accessibility and Exploration

This asteroid is not considered a viable target for human exploration by the NHATS study.
