Key Facts


543375 (2014 BX64) is a very large asteroid whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified 2014 BX64 as potentially hazardous because its orbit does not bring it close to Earth.

2014 BX64 orbits the sun every 98,200 days (268.86 years), coming as close as 39.69 AU and reaching as far as 43.63 AU from the sun. Based on its brightness and the way it reflects light, 2014 BX64 is probably between 183.889 to 411.188 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. state of Maryland.

No Close Approaches

2014 BX64's orbit is 38.70 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 BX64's orbit is determined by observations dating back to Jan. 14, 2002. It was last officially observed on Oct. 23, 2020. The IAU Minor Planet Center records 178 observations used to determine its orbit.

Accessibility and Exploration

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