... The volume of the nucleus of P/Halley was larger than expected. Given the apparent magnitude of the comet before it reaches the sun, the Bond and geometric albedos work out to ≈ 0.05 and ≈ 0.03, respectively, which makes P/Halley one of the darkest known objects in the solar system. The implication ...
