Hidalgo is a large asteroid with an orbit between Jupiter and Neptune. NASA JPL has not classified Hidalgo as potentially hazardous because its orbit does not bring it close to Earth.
Hidalgo orbits the sun every 5,010 days (13.72 years), coming as close as 1.95 AU and reaching as far as 9.52 AU from the sun. Hidalgo is about 38.0 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Houston.
The rotation of Hidalgo has been observed. It completes a rotation on its axis every 10.06 hours.
Hidalgo's orbit is 1.15 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.
Hidalgo's orbit is determined by observations dating back to Oct. 31, 1920. It was last officially observed on Jan. 17, 2021. The IAU Minor Planet Center records 1,822 observations used to determine its orbit.
Scientists have been able to determine this object's shape.
