2008 SR1 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2008 SR1 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2008 SR1 orbits the sun every 1,330 days (3.64 years), coming as close as 0.83 AU and reaching as far as 3.91 AU from the sun. Based on its brightness and the way it reflects light, 2008 SR1 is probably between 0.232 to 0.518 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.
2008 SR1's orbit is 0.03 AU from Earth's orbit at its closest point. This means that there is an wide berth between this asteroid and Earth at all times.
2008 SR1 has 4 close approaches predicted in the coming decades:
|Date||Distance from Earth (km)||Velocity (km/s)|
|Sept. 9, 2019||14,001,330||15.774|
|Sept. 28, 2081||29,669,074||23.108|
|Sept. 23, 2154||17,814,564||20.666|
|Sept. 9, 2165||11,132,580||16.228|
2008 SR1's orbit is determined by observations dating back to Sept. 23, 2008. It was last officially observed on Oct. 31, 2019. The IAU Minor Planet Center records 233 observations used to determine its orbit.
