Asterank provides a queryable database containing information on over 2,000 exoplanets and unconfirmed "objects of interest" collected through NASA's Kepler Project. The Kepler spacecraft detects planets outside our solar system (a.k.a. exoplanets) by observing the decrease in light caused when a planet passes in front of a star. The Asterank Kepler Project database is updated nightly from the Kepler Data Explorer. Because Asterank's database runs on MongoDB, queries must adhere to Mongo's JSON format.
