Norwan is a mid-sized asteroid whose orbit approaches the orbit of Earth but does not cross it. NASA JPL has classified Norwan 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.
Norwan orbits the sun every 717 days (1.96 years), coming as close as 1.07 AU and reaching as far as 2.06 AU from the sun. Based on its brightness and the way it reflects light, Norwan is probably between 1.058 to 2.366 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. Pentagon.
The rotation of Norwan has been observed. It completes a rotation on its axis every 35.90 days.
Norwan's orbit is 0.16 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.
Norwan has 3 close approaches predicted in the coming decades:
|Date||Distance from Earth (km)||Velocity (km/s)|
|Sept. 10, 2049||24,650,652||6.231|
|Sept. 13, 2102||24,383,851||5.693|
|Sept. 14, 2155||24,523,227||5.536|
Norwan's orbit is determined by observations dating back to May 1, 1982. It was last officially observed on July 25, 2019. The IAU Minor Planet Center records 1,049 observations used to determine its orbit.
