YZ Cet - System
YZ Cet, a cool M-dwarf of 0.14 solar masses, and YZ Cet b, a 0.7-Earth-mass planet, with an orbital period of 2.0 days, at 0.016 AU from its star, and an equilibrium temperature near 471 K, on an eccentric.
rho CrB - System
rho CrB, a Sun-like G-type star of 1.00 solar masses with 3 confirmed companions (rho CrB e, rho CrB b, rho CrB c) on NASA archive orbits.
tau Cet - System
Tau Ceti, the nearest single Sun-like star. Its compact super-Earths make this neighbor a long-standing target in the search for nearby worlds.
ups And - System
Upsilon Andromedae, the first multi-planet system found around a main-sequence star. Three giants on mutually tilted, eccentric orbits tug one another.
