143678 (2003 SA224) is a mid-sized asteroid whose orbit approaches the orbit of Earth but does not cross it. NASA JPL has classified 2003 SA224 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.
2003 SA224 orbits the sun every 774 days (2.12 years), coming as close as 1.11 AU and reaching as far as 2.19 AU from the sun. Based on its brightness and the way it reflects light, 2003 SA224 is probably between 1.395 to 3.119 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to Mount Everest.
The rotation of 2003 SA224 has been observed. It completes a rotation on its axis every 35.00 hours.
2003 SA224's orbit is 0.15 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.
2003 SA224 has 4 close approaches predicted in the coming decades:
Date | Distance from Earth (km) | Velocity (km/s) |
---|---|---|
March 10, 2042 | 23,505,717 | 7.759 |
March 10, 2078 | 22,794,611 | 8.231 |
March 12, 2114 | 26,540,718 | 9.059 |
March 13, 2167 | 28,778,730 | 7.516 |
2003 SA224's orbit is determined by observations dating back to Oct. 9, 1979. It was last officially observed on June 22, 2023. The IAU Minor Planet Center records 1,802 observations used to determine its orbit.
