Telescope to monitor a single start for two years to find transiting exoplanets.

Description

Prototype nanosatellite capable of monitoring a single, bright, sun-like star for two years. Previously called ExoplanetSat, it develop into a suite of nanosatellites, each focusing on one bright star at a time. The science motivation is to search for transiting exoplanets orbiting the brightest sun-like stars in the sky.

Results

ASTERIA made a marginal detection of the known transiting exoplanet 55 Cancri e (∼ 2 R⊕), measuring a transit depth of 374 ± 170 ppm. This is the first detection of an exoplanet by a CubeSat.
