6178 (1986 DA) is a mid-sized asteroid whose orbit approaches the orbit of Earth but does not cross it. NASA JPL has classified 1986 DA 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.
1986 DA orbits the sun every 1,720 days (4.71 years), coming as close as 1.17 AU and reaching as far as 4.46 AU from the sun. 1986 DA is about 2.3 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to Mount Everest.
The rotation of 1986 DA has been observed. It completes a rotation on its axis every 3.50 hours.
1986 DA's orbit is 0.18 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.
1986 DA has 2 close approaches predicted in the coming decades:
Date | Distance from Earth (km) | Velocity (km/s) |
---|---|---|
April 7, 2038 | 29,624,848 | 4.858 |
April 6, 2076 | 29,004,937 | 4.901 |
1986 DA's orbit is determined by observations dating back to July 17, 1977. It was last officially observed on Dec. 25, 2022. The IAU Minor Planet Center records 1,115 observations used to determine its orbit.
