Ninkasi is a small asteroid whose orbit approaches the orbit of Earth but does not cross it. NASA JPL has classified Ninkasi 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.
Ninkasi orbits the sun every 586 days (1.60 years), coming as close as 1.14 AU and reaching as far as 1.60 AU from the sun. Based on its brightness and the way it reflects light, Ninkasi is probably between 0.665 to 1.486 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.
The rotation of Ninkasi has been observed. It completes a rotation on its axis every 21.10 hours.
Ninkasi's orbit is 0.15 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.
Ninkasi has 7 close approaches predicted in the coming decades:

Ninkasi's orbit is determined by observations dating back to Feb. 17, 1978. It was last officially observed on Jan. 16, 2021. The IAU Minor Planet Center records 728 observations used to determine its orbit.
