Asteroid 2012 KT42
The Planetary Spectroscopy group at MIT primarily study asteroids, both in the asteroid belt and those that approach the Earth (as well as others, where available!). We use reflectance spectroscopy to classify objects based on their spectral properties as well as doing more detailed studies of their composition.
We use a number of telescopes for our studies, including the Infrared Telescope Facility and the Keck Telescopes on Mauna Kea, telescopes on Kitt Peak in Arizona, and the Magellan telescopes in Chile. We have even published results using data from the Wallace Observatory here in Massachusetts!
