Overview
2004 RQ10 is a very small asteroid whose orbit approaches the orbit of Earth but does not cross it. NASA JPL has classified 2004 RQ10 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2004 RQ10 orbits the sun every 930 days (2.55 years), coming as close as 1.04 AU and reaching as far as 2.69 AU from the sun. Based on its brightness and the way it reflects light, 2004 RQ10 is probably between 0.176 to 0.393 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.
The rotation of 2004 RQ10 has been observed. It completes a rotation on its axis every 5.69 hours.
Close Approaches
2004 RQ10's orbit is 0.03 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.
2004 RQ10 has 6 close approaches predicted in the coming decades:
| Date | Distance from Earth (km) | Velocity (km/s) |
|---|---|---|
| Sept. 12, 2032 | 16,764,241 | 9.046 |
| July 13, 2055 | 28,641,566 | 10.933 |
| Aug. 9, 2083 | 7,751,287 | 6.646 |
