Key Facts

Overview

555632 (2014 BZ57) is a dwarf planet whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified 2014 BZ57 as potentially hazardous because its orbit does not bring it close to Earth.

2014 BZ57 orbits the sun every 102,000 days (279.26 years), coming as close as 36.85 AU and reaching as far as 48.43 AU from the sun. Based on its brightness and the way it reflects light, 2014 BZ57 is probably between 270.742 to 605.397 kilometers in diameter, making it one of the largest objects, very roughly comparable in size to the U.S. state of Pennsylvania.

No Close Approaches

2014 BZ57's orbit is 36.00 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

2014 BZ57's orbit is determined by observations dating back to Dec. 11, 2002. It was last officially observed on March 27, 2023. The IAU Minor Planet Center records 263 observations used to determine its orbit.

Accessibility and Exploration

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