Weird Object: Asteroid 90 Antiope

• arclein

n Antiope's region, asteroids are always dark, displaying the spectral signature of carbonaceous material. These asteroids are also renowned for their skimpy, low-density construction (1.3 g/cm³), just barely heftier than water ice, but with a pitch-black surface that reflects a mere 6 percent of incoming sunlight. They are all darker than the lunar "seas" on our Moon and much blacker than asphalt.
