Ino is a large asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified Ino as potentially hazardous because its orbit does not bring it close to Earth.
Ino orbits the sun every 1,660 days (4.54 years), coming as close as 2.17 AU and reaching as far as 3.32 AU from the sun. Ino is about 125.8 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the U.S. state of Connecticut.
The rotation of Ino has been observed. It completes a rotation on its axis every 6.15 hours.
Ino's spectral type C (Tholen) / Xk (SMASSII) indicates that it is likely to contain iron, nickel, and cobalt.
Ino's orbit is 1.19 AU from Earth's orbit at its closest point. This means that there is an extremely wide berth between this asteroid and Earth at all times.
Orbital simulations conducted by NASA JPL's CNEOS do not show any close approaches to Earth.
Ino's orbit is determined by observations dating back to Jan. 20, 1879. It was last officially observed on July 4, 2023. The IAU Minor Planet Center records 4,279 observations used to determine its orbit.
