Overview
2008 SV11 is a small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2008 SV11 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2008 SV11 orbits the sun every 1,540 days (4.22 years), coming as close as 0.71 AU and reaching as far as 4.50 AU from the sun. Its orbit is highly elliptical. Based on its brightness and the way it reflects light, 2008 SV11 is probably between 0.566 to 1.265 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.
The rotation of 2008 SV11 has been observed. It completes a rotation on its axis every 32.40 hours.
Close Approaches
2008 SV11'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.
2008 SV11 has 2 close approaches predicted in the coming decades:
| Date | Distance from Earth (km) | Velocity (km/s) |
|---|---|---|
| April 3, 2127 | 13,356,057 | 20.457 |
| April 7, 2165 | 19,962,916 | 21.915 |
Images and Observations
2008 SV11's orbit is determined by observations dating back to Sept. 25, 2008. It was last officially observed on Sept. 10, 2021. The IAU Minor Planet Center records 594 observations used to determine its orbit.
