Comets have been in the news lately. The Philae Lander from ESA's Rosetta spacecraft touched down on Comet 67 P, and other comets, such as Comet Siding Spring and ISON have come close to Mars in the last year. Comets have a lot less gravity than our Earth, so this made it very challenging for the Philae Lander to land on 67 P. As 67 P gets closer to the Sun, then it is hoped that the Philae Lander on 67 P will receive more sunlight and then will finally wake up, and start talking to Earth. Asteroid Bennu will also discussed.
