16 Cyg B - System
16 Cygni B b, a giant with eccentricity near 0.7. The distant stellar companion 16 Cygni A is the usual suspect for pumping that extreme orbit.

2MASS J12073346-3932539 - System
2M1207 b, the first planetary-mass object ever imaged. It orbits a young brown dwarf, wide enough to be seen directly in infrared light. The 2004 image was taken with the Very Large Telescope.
47 UMa - System
47 Ursae Majoris, one of the first Sun-like stars found to host Jupiter-like planets on year-long orbits rather than a scorched hot Jupiter.
51 Eri - System
51 Eridani b, a young Jupiter analog imaged in a debris disk. Its methane-rich atmosphere looks more like Jupiter's than most imaged giants.
51 Peg - System
51 Pegasi b, the first planet found around a Sun-like star. This 1995 hot Jupiter won Michel Mayor and Didier Queloz the 2019 Nobel Prize in Physics.
55 Cnc - System
Nearby 55 Cancri, a five-planet system about 41 light-years away. Inner world 55 Cnc e is a lava super-Earth and a prime target for JWST. The host also has a distant red-dwarf companion.
70 Vir - System
70 Virginis b, a massive eccentric giant announced in 1996. It was one of the first exoplanets and briefly a candidate for a habitable moon host.
AU Mic - System
AU Microscopii, a young nearby red dwarf still wrapped in a debris disk. Its transiting planets are puffy worlds that have barely finished forming.
Barnard's star - System
Barnard's Star, the nearest single star to the Sun. Its low-mass planets are among the closest known worlds beyond the Solar System. The star is famous for its rapid motion across the sky.
CI Tau - System
CI Tauri c, a giant planet on a 25-day eccentric orbit. The host is only about 2 million years old and still surrounded by a protoplanetary disk.
CoRoT-1 - System
CoRoT-1 b, the first exoplanet whose changing phases were seen in visible light. The orbiting hot Jupiter brightens and fades like a moon. The signal is the planet's own changing brightness.
CoRoT-7 - System
CoRoT-7 b, the first super-Earth found to transit and a leading candidate for the first rocky exoplanet, baked on an orbit of less than a day.
GJ 1002 - System
GJ 1002, a nearby quiet red dwarf with two Earth-mass planets in the habitable zone, among the closest temperate worlds known. Both planets were found by radial-velocity monitoring.
GJ 1132 - System
GJ 1132 b, a nearby rocky planet that may have lost and then rebuilt an atmosphere. It is a key JWST target for secondary atmospheres. The red dwarf is only about 41 light-years from the Sun.
GJ 1214 - System
GJ 1214 b, the archetype sub-Neptune. This nearby mini-Neptune has a famously flat transmission spectrum, hiding water, haze, or both. The red-dwarf host is only about 48 light-years away.
GJ 273 - System
GJ 273, Luyten's Star, a nearby red dwarf only 12 light-years away. Its planets include a world near the inner edge of the habitable zone. Radial velocities revealed the planets.
GJ 357 - System
GJ 357, a nearby red dwarf with a transiting hot Earth and an outer habitable-zone planet. The outer world does not transit. The system is about 31 light-years from the Sun.
GJ 367 - System
GJ 367 b, an iron-rich world on an ultra-short orbit. A year lasts about eight hours, and the high density points to an exposed iron core. The density is higher than Earth's.
