Overview
2011 BE38 is a small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2011 BE38 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2011 BE38 orbits the sun every 1,560 days (4.27 years), coming as close as 0.76 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, 2011 BE38 is probably between 0.568 to 1.271 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
2011 BE38'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.
2011 BE38 has 2 close approaches predicted in the coming decades:
| Date | Distance from Earth (km) | Velocity (km/s) |
|---|---|---|
| April 3, 2058 | 20,289,938 | 19.737 |
| April 3, 2092 | 25,730,437 | 20.462 |
Images and Observations
2011 BE38's orbit is determined by observations dating back to Jan. 28, 2011. It was last officially observed on Jan. 24, 2015. The IAU Minor Planet Center records 158 observations used to determine its orbit.
