アエトラ (小惑星)
1. 132 AethraDiscovered by James Craig Watson in 1873, 132 Aethra is an M-type main-belt asteroid. It has a rather eccentric orbit that sometimes brings it closer to the Sun than the planet Mars. It was the first such Mars-crosser asteroid to be identified. As a Mars-crosser asteroid, Aethra is the lowest numbered asteroid to not have proper orbital elements due to recurring perturbations by Mars. With an original observation arc of only 22 days, 132 Aethra was a lost asteroid between 1873 and 1922.
