  We present the target selection for the Breakthrough Listen search for
extraterrestrial intelligence during the first year of observations at the
Green Bank Telescope, Parkes Telescope and Automated Planet Finder. On the way
to observing 1,000,000 nearby stars in search of technological signals, we
present three main sets of objects we plan to observe in addition to a smaller
sample of exotica. We choose the 60 nearest stars, all within 5.1 pc from the
sun. Such nearby stars offer the potential to observe faint radio signals from
transmitters having a power similar to those on Earth. We add a list of 1649
stars drawn from the Hipparcos catalog that span the Hertzprung-Russell
diagram, including all spectral types along the main sequence, subgiants, and
giant stars. This sample offers diversity and inclusion of all stellar types,
but with thoughtful limits and due attention to main sequence stars. Our
targets also include 123 nearby galaxies composed of a
"morphological-type-complete" sample of the nearest spirals, ellipticals, dwarf
spherioidals, and irregulars. While their great distances hamper the detection
of technological electromagnetic radiation, galaxies offer the opportunity to
observe billions of stars simultaneously and to sample the bright end of the
technological luminosity function. We will also use the Green Bank and Parkes
telescopes to survey the plane and central bulge of the Milky Way. Finally, the
complete target list includes several classes of exotica, including white
dwarfs, brown dwarfs, black holes, neutron stars, and asteroids in our Solar
System.
