Kepler-9 - System
Kepler-9, the first planets confirmed by transit timing variations. The two giants tug each other so hard their transit clocks drift. A smaller inner world, Kepler-9 d, transits as well.

L 98-59 - System
L 98-59, a nearby compact system around a bright red dwarf. The inner planet may be volcanic, and outer worlds sit near the habitable zone. The host is bright enough for detailed JWST spectra.
LHS 1140 - System
LHS 1140, a nearby red dwarf with a rocky habitable-zone super-Earth. LHS 1140 b is a leading target for atmospheric study with JWST. An inner planet, LHS 1140 c, transits the star as well.
LHS 3844 - System
LHS 3844 b, a bare-rock planet with no detected atmosphere. Its dayside phase curve shows heat reradiated straight from the surface. The world orbits in only about 11 hours.
LP 890-9 - System
LP 890-9, also SPECULOOS-2, an ultracool dwarf with two Earth-sized planets. The outer one transits in the habitable zone. The host is one of the coolest stars known to have planets.
NGTS-10 - System
NGTS-10 b, an ultra-short-period hot Jupiter orbiting in about 18 hours. Tides are expected to drag this already-close planet inward. It was found by the Next-Generation Transit Survey.
OGLE-2005-BLG-390L - System
OGLE-2005-BLG-390L b, a cold super-Earth found by gravitational microlensing. It was the first icy, low-mass planet detected far from its star.
OGLE-TR-56 - System
OGLE-TR-56 b, the first planet discovered by the transit method itself. Earlier transiting worlds had already been found by radial velocity.
PDS 70 - System
PDS 70, the first system where planets were seen still forming. Two giants sit inside a gap they have cleared in the protoplanetary disk. Both PDS 70 b and c are still accreting gas.
PH1 - System
PH1, or Kepler-64 b, a planet in a quadruple star system. It orbits one stellar pair while a second binary shines in the distance. Volunteers in Planet Hunters spotted it in Kepler data.
PSR B1257+12 - System
PSR B1257+12, the first confirmed exoplanets. In 1992 pulsar timing revealed three worlds, including a Moon-mass body, around a dead star. The host is a millisecond pulsar, not a living star.
PSR B1620-26 - System
The Methuselah planet PSR B1620-26 b, about 12.7 billion years old. It circles a pulsar and white dwarf in the globular cluster Messier 4. Its orbit around the pair takes roughly a century.
PSR J1719-1438 - System
PSR J1719-1438 b, the so-called diamond planet. This ultra-dense remnant orbits a millisecond pulsar every 2.2 hours and may be crystallized carbon.
Proxima Cen - System
Proxima Centauri, the nearest star to the Sun. Proxima b is an Earth-mass world in the habitable zone, only 4.2 light-years away. The host is a flare-active red dwarf in Alpha Centauri.
Ross 128 - System
Ross 128 b, a temperate Earth-mass planet about 11 light-years away. Its quiet red-dwarf host is a neighbor of Proxima Centauri. It receives a similar amount of starlight to the Earth.
SPECULOOS-3 - System
SPECULOOS-3 b, an Earth-sized planet on a 17-hour orbit around an ultracool dwarf. It is a nearby laboratory for bare, roasted rock. The host is only about 55 light-years away.
TOI-1136 - System
TOI-1136, a young compact six-planet system. The planets are still losing formation heat, so they look puffier than older worlds of the same mass.
TOI-1338 A - System
TOI-1338, a TESS circumbinary system. Planets orbit both members of an eclipsing binary, a Tatooine architecture found after Kepler. The binary eclipses, and planets b and c orbit both stars.
