Overview
2014 SS1 is a very small asteroid whose orbit approaches the orbit of Earth but does not cross it. NASA JPL has classified 2014 SS1 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2014 SS1 orbits the sun every 1,130 days (3.09 years), coming as close as 1.02 AU and reaching as far as 3.22 AU from the sun. Based on its brightness and the way it reflects light, 2014 SS1 is probably between 0.121 to 0.272 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a basketball court.
The rotation of 2014 SS1 has been observed. It completes a rotation on its axis every 16.63 hours.
Close Approaches
2014 SS1'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.
2014 SS1 has 4 close approaches predicted in the coming decades:
| Date | Distance from Earth (km) | Velocity (km/s) |
|---|---|---|
| Aug. 13, 2079 | 5,349,500 | 7.670 |
| Sept. 29, 2116 | 11,596,217 | 8.892 |
| Oct. 4, 2150 | 13,424,334 | 9.621 |
| July 31, 2181 | 17,201,048 | 10.313 |
Images and Observations
2014 SS1's orbit is determined by observations dating back to Sept. 10, 2014. It was last officially observed on June 24, 2017. The IAU Minor Planet Center records 288 observations used to determine its orbit.
