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.
2MASS J16262785-2625152 - System
2MASS J16262785-2625152, a cool M-dwarf of 1.00 solar masses, and KOINTREAU-4 b, a 15.3-Jupiter-mass companion, at 182 AU from its star.
2MASS J19383260+4603591 - System
2MASS J19383260+4603591, and 2MASS J19383260+4603591 b, a 1.86-Jupiter-mass companion, with an orbital period of 1.11 years, on an eccentric orbit (e ≈ 0.33).
2MASS J21252752-8138278 - System
2MASS J21252752-8138278, a cool M-dwarf of 0.64 solar masses, and 2MASS J21252752-8138278 b, a 12.0-Jupiter-mass companion, at 7,493 AU from its star, and an equilibrium temperature near 1,616 K.
2MASS J22362452+4751425 - System
2MASS J22362452+4751425, an orange K-type dwarf of 0.60 solar masses, and 2MASS J22362452+4751425 b, a 12.5-Jupiter-mass companion, at 230 AU from its star.
2MASS J22501512+2325342 - System
2MASS J22501512+2325342, a cool M-dwarf of 0.43 solar masses, and 2MASS J22501512+2325342 b, a 30.0-Jupiter-mass companion, at 518 AU from its star, and an equilibrium temperature near 1,600 K.
4 UMa - System
4 UMa, an orange K-type dwarf of 1.23 solar masses, and 4 UMa b, a 7.90-Jupiter-mass companion, with an orbital period of 270 days, at 0.877 AU from its star, on an eccentric orbit (e ≈ 0.45).
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.
55 Cnc B - System
55 Cnc B, a cool M-dwarf of 0.26 solar masses, and 55 Cnc B b, a 3.5-Earth-mass planet, with an orbital period of 6.8 days, at 0.044 AU from its star.
6 Lyn - System
6 Lyn, an orange K-type dwarf of 1.32 solar masses, and 6 Lyn b, a 1.88-Jupiter-mass companion, with an orbital period of 2.52 years, at 2.028 AU from its star.

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.
75 Cet - System
75 Cet, a Sun-like G-type star of 1.92 solar masses, and 75 Cet b, a 2.48-Jupiter-mass companion, with an orbital period of 1.91 years, at 1.912 AU from its star, on an eccentric orbit (e ≈ 0.09).
