5660 (1974 MA) is a mid-sized asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 1974 MA 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.
1974 MA orbits the sun every 871 days (2.38 years), coming as close as 0.43 AU and reaching as far as 3.15 AU from the sun. Its orbit is highly elliptical. Based on its brightness and the way it reflects light, 1974 MA is probably between 2.092 to 4.678 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to Mount Everest.
The rotation of 1974 MA has been observed. It completes a rotation on its axis every 17.50 hours.
1974 MA's orbit is 0.16 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.
1974 MA has 3 close approaches predicted in the coming decades:
|Date||Distance from Earth (km)||Velocity (km/s)|
|Aug. 4, 2036||24,668,187||29.898|
|Aug. 5, 2067||25,806,316||29.186|
|Aug. 4, 2098||26,685,400||30.091|
1974 MA's orbit is determined by observations dating back to June 26, 1974. It was last officially observed on April 22, 2020. The IAU Minor Planet Center records 284 observations used to determine its orbit.
