Key Facts


315615 (2008 CZ184) is a very small asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified 2008 CZ184 as potentially hazardous because its orbit does not bring it close to Earth.

2008 CZ184 orbits the sun every 1,520 days (4.16 years), coming as close as 2.11 AU and reaching as far as 3.07 AU from the sun. Based on its brightness and the way it reflects light, 2008 CZ184 is probably between 0.64 to 1.43 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to the Golden Gate Bridge.

No Close Approaches

2008 CZ184's orbit is 1.12 AU from Earth's orbit at its closest point. This means that there is a 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

2008 CZ184's orbit is determined by observations dating back to Oct. 5, 2002. It was last officially observed on Jan. 7, 2016. The IAU Minor Planet Center records 73 observations used to determine its orbit.

Accessibility and Exploration

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