More on Hidalgo
Asteroid - planetoid, or minor planet, small body orbiting the sun.
944 Hidalgo is an unusual asteroid, and has the longest orbital period (13.77 years) of any asteroid in the traditional asteroid belt.
Hidalgo
Asteroid 944, perhaps 20 km in diameter, with the largest known orbit (a = 5.8 AU), second highest inclination to the ecliptic (42°.5), and second highest eccentricity (e = 0.66) of any known minor planet. Period 13.7 years.
944 Hidalgo has a highly elliptical orbit which carries it from the main asteroid belt between Mars and Jupiter to out beyond Saturn. Some think that 944 Hidalgo is actually an extinct comet.

In contrast to the examples of Phaethon and Hidalgo is Chiron, which following its discovery in 1977 was classified as an asteroid, (2060) Chiron.
The European Space Agency has plans for an asteroid mission called Don Quixote, which would send two spacecraft - Sancho and Hidalgo - on different trajectories to the same asteroid. Sancho would arrive first and go into orbit at a safe distance.
But some asteroids, such (3200) Phaethon and (944) Hidalgo, have highly inclined and/or elliptical paths, suggesting they may be defunct cometary nuclei. Rotational periods of asteroids range from 2.
