Overview

612356 (2002 JX8) is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2002 JX8 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2002 JX8 orbits the sun every 247 days (0.68 years), coming as close as 0.53 AU and reaching as far as 1.00 AU from the sun. Based on its brightness and the way it reflects light, 2002 JX8 is probably between 0.149 to 0.668 kilometers in diameter, making it larger than 90% of asteroids but tiny compared to large asteroids, very roughly comparable in size to the U.S. Capitol building.

Close Approaches

2002 JX8's orbit is 0.02 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.

2002 JX8 has 26 close approaches predicted in the coming decades:

Images and Observations

2002 JX8's orbit is determined by observations dating back to May 4, 2002. It was last officially observed on May 2, 2023. The IAU Minor Planet Center records 102 observations used to determine its orbit.

Accessibility and Exploration

2002 JX8 can be reached with a journey of 354 days. This trajectory would require a delta-v of 10.42 km/s. To put this into perspective, the delta-v to launch a rocket to Low-Earth Orbit is 9.7 km/s. There are 870 potential trajectories and launch windows to this asteroid.
