Asteroid Albedos & Consequences for Detection by NEA Survey Programs Contributed by

This article explores the difficulties of detecting dark asteroids with low albedos in NEA survey programs. It highlights the trade-off between detection size limit and survey speed, emphasizing the challenges of searching for coal-like objects against the vastness of space.

  2. Astronomy: Sky Surveys • Great idea! But not so simple in practice… • It’s a big solar system out there! • Trade off between detection size limit and survey speed/effectiveness. • Asteroids are dark… much like asteroid Eros (10 km x 30 km) shown here (it really is here, even if you cannot see it) • with albedos of a few percent, think looking for lumps of coal set against the black vastness of space! Eros’ Albedo: 5%
