Automated Planet Finder

(robotic telescope to find exoplanets using RV method)

The Automated Planet Finder (APF) is a robotic 2.4-meter telescope at Lick Observatory, designed and built to search for extra-solar planets using the radial velocity method, which went into service in 2014. It can examine about 10 stars per night with an HRS spectrometer (Levy Spectrometer) capable of detecting an RV delta of 1 meter per second. It aims to survey stars within 100 ly. Among its discoveries is an apparent super-Earth orbiting Barnard's Star, announced in November 2018.
