Overview
65674 (1988 SM) is a small asteroid whose orbit approaches the orbit of Earth but does not cross it. NASA JPL has classified 1988 SM 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.
1988 SM orbits the sun every 784 days (2.15 years), coming as close as 1.09 AU and reaching as far as 2.24 AU from the sun. Based on its brightness and the way it reflects light, 1988 SM is probably between 0.587 to 1.312 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
1988 SM's orbit is 0.13 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.
1988 SM has 4 close approaches predicted in the coming decades:
| Date | Distance from Earth (km) | Velocity (km/s) |
|---|---|---|
| Aug. 31, 2046 | 20,247,002 | 6.835 |
| Sept. 6, 2061 | 28,050,616 | 9.695 |
| Sept. 2, 2119 | 19,953,833 | 6.908 |
| Sept. 2, 2192 | 19,324,828 | 7.206 |
Images and Observations
1988 SM's orbit is determined by observations dating back to Sept. 29, 1988. It was last officially observed on March 26, 2022. The IAU Minor Planet Center records 333 observations used to determine its orbit.
