• Classified as a Near Earth Asteroid (NEA)
• Not a Potentially Hazardous Object
• See orbit simulation

Overview

2002 JR100 is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2002 JR100 as a "Near Earth Asteroid" due to its orbit's proximity to Earth, but it is not considered potentially hazardous because computer simulations have not indicated any imminent likelihood of future collision.

2002 JR100 orbits the sun every 324 days (0.89 years), coming as close as 0.65 AU and reaching as far as 1.20 AU from the sun. 2002 JR100 is about 0.0 kilometers in diameter, making it a small to average asteroid, comparable in size to a school bus or smaller.

Close Approaches

2002 JR100'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 JR100 has 35 close approaches predicted in the coming decades:

Images and Observations

2002 JR100's orbit is determined by observations dating back to May 14, 2002. It was last officially observed on July 31, 2019. The IAU Minor Planet Center records 149 observations used to determine its orbit.

Accessibility and Exploration

2002 JR100 can be reached with a journey of 386 days. This trajectory would require a delta-v of 8.629 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 46,606 potential trajectories and launch windows to this asteroid.
