Ivar is a mid-sized asteroid whose orbit approaches the orbit of Earth but does not cross it. NASA JPL has classified Ivar 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.
Ivar orbits the sun every 929 days (2.54 years), coming as close as 1.12 AU and reaching as far as 2.60 AU from the sun. Ivar is about 9.1 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the San Francisco Bay.
The rotation of Ivar has been observed. It completes a rotation on its axis every 4.80 hours.
Ivar's orbit is 0.11 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.
Ivar has 4 close approaches predicted in the coming decades:
|Date||Distance from Earth (km)||Velocity (km/s)|
|Aug. 6, 2046||26,550,529||7.832|
|Aug. 3, 2074||21,054,469||6.971|
|Aug. 6, 2102||23,479,879||7.314|
|July 21, 2181||24,904,092||6.794|
Ivar's orbit is determined by observations dating back to Sept. 25, 1929. It was last officially observed on Dec. 26, 2021. The IAU Minor Planet Center records 7,473 observations used to determine its orbit.
Scientists have been able to determine this object's shape.
