Overview
154988 (2004 XN35) is a small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2004 XN35 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.
2004 XN35 orbits the sun every 675 days (1.85 years), coming as close as 0.48 AU and reaching as far as 2.53 AU from the sun. Based on its brightness and the way it reflects light, 2004 XN35 is probably between 0.558 to 1.247 kilometers in diameter, making it larger than ~97% of asteroids but small compared to large asteroids, very roughly comparable in size to the Golden Gate Bridge.
Close Approaches
2004 XN35's orbit is 0.15 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 XN35 has 6 close approaches predicted in the coming decades:
| Date | Distance from Earth (km) | Velocity (km/s) |
|---|---|---|
| April 25, 2069 | 26,201,964 | 23.446 |
| Nov. 26, 2089 | 27,401,687 | 19.183 |
| April 29, 2093 | 25,999,206 | 21.280 |
| Dec. 2, 2113 | 22,721,900 | 21.836 |
| Dec. 8, 2137 | 28,266,096 | 25.764 |
| Dec. 1, 2174 | 23,673,736 | 20.839 |
