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 0.668 to 1.493 kilometers in diameter, making it small in absolute terms, but larger than ~97% of asteroids, very roughly comparable in size to the Golden Gate Bridge.
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 June 22, 2020. The IAU Minor Planet Center records 556 observations used to determine its orbit.
