More Apophis news: New data from the Herschel Space Telescope suggests that the asteroid is bigger and less reflective than previous believed.

Instead of 900 feet across, they now estimate it has a diameter of about 1070 feet. And knowing that the asteroid has a lower albedo means that astronomers will be better able to gauge the effect of solar radiation on Apophis’s orbit.
