  Transiting Exoplanet Survey Satellite (TESS) observations have revealed a
compact multi-planet system around the sixth-magnitude star HR 858 (TIC
178155732, TOI 396), located 32 parsecs away. Three planets, each about twice
the size of Earth, transit this slightly-evolved, late F-type star, which is
also a member of a visual binary. Two of the planets may be in mean motion
resonance. We analyze the TESS observations, using novel methods to model and
remove instrumental systematic errors, and combine these data with follow-up
observations taken from a suite of ground-based telescopes to characterize the
planetary system. The HR 858 planets are enticing targets for precise radial
velocity observations, secondary eclipse spectroscopy, and measurements of the
Rossiter-McLaughlin effect.
