Overview
2007 PR25 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2007 PR25 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2007 PR25 orbits the sun every 999 days (2.74 years), coming as close as 0.30 AU and reaching as far as 3.61 AU from the sun. Its orbit is highly elliptical. Based on its brightness and the way it reflects light, 2007 PR25 is probably between 0.106 to 0.237 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a basketball court.
Close Approaches
2007 PR25's orbit is 0.01 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.
NASA Sentry has assessed impact risk for 1 very close approach scenarios. Here are the top scenarios ordered by probability of impact:
| Date | Probability of Impact (%) | Impact Energy (Mt) |
|---|---|---|
| Aug. 19, 2118 | 0.00000 | 469.7 |
Images and Observations
2007 PR25's orbit is determined by observations dating back to Aug. 13, 2007. It was last officially observed on Aug. 20, 2007. The IAU Minor Planet Center records 43 observations used to determine its orbit.
