Overview
2004 LY5 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2004 LY5 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2004 LY5 orbits the sun every 905 days (2.48 years), coming as close as 0.41 AU and reaching as far as 3.26 AU from the sun. Its orbit is highly elliptical. Based on its brightness and the way it reflects light, 2004 LY5 is probably between 0.123 to 0.274 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a basketball court.
Close Approaches
2004 LY5'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.
2004 LY5 has 6 close approaches predicted in the coming decades:
| Date | Distance from Earth (km) | Velocity (km/s) |
|---|---|---|
| June 28, 2056 | 22,379,756 | 22.737 |
| June 15, 2061 | 19,497,576 | 30.537 |
| Jan. 28, 2074 | 29,097,656 | 27.150 |
