DMPP-8 b

DMPP-8 b, a gas giant of ~0.26 Jupiter masses (~81 Earth masses), circles an F-type star with a 63-day period at 0.31 AU. Radius ~0.96 Jupiter (~11 Earth radii), it’s a warm giant added March 2026 via radial velocity. Part of DMPP’s focus on ablated planets, it may show signs of atmospheric erosion. The system’s […]

DMPP-7 b

DMPP-7 b is a hot gas giant with ~0.19 Jupiter masses (~61 Earth masses), orbiting an F-type star in the Dispersed Matter Planet Project survey. Its tight 5-day orbit at 0.06 AU makes it a puffy, irradiated world with estimated radius ~0.8 Jupiter (~9 Earth radii). Added to the archive March 2026, it exemplifies close-in […]

GJ 1137 b

GJ 1137 b is a sub-Jupiter gas giant with ~0.45 Jupiter masses (~143 Earth masses), orbiting the K2 dwarf GJ 1137 at 93 light-years. Its 145-day period places it near the optimistic habitable zone, where a thick hydrogen envelope might support exotic life forms or habitable moons. Refined via extended RV data spanning 2005-2026, amid […]

KMT-2024-BLG-0176L b

KMT-2024-BLG-0176L b is a gas giant exoplanet with 0.76 Jupiter masses, orbiting its unknown-type host star every 4.7 years at 1.32 AU. Detected through microlensing in 2026 by the Korea Microlensing Telescope Network, it lies toward the Milky Way’s bulge, far from the habitable zone in a likely cold, distant environment. Microlensing events like this […]

KOINTREAU-4 b

KOINTREAU-4 b is an enormous gas giant exoplanet boasting 15.3 Jupiter masses, orbiting an M-type red dwarf at a projected separation of about 180 AU with a long orbital period. Detected through adaptive optics imaging in the 2026 KOINTREAU survey of ultracool dwarfs in ρ Ophiuchi, its wide orbit challenges formation theories, possibly indicating capture […]

KOINTREAU-3 b

KOINTREAU-3 b is a massive gas giant exoplanet with 3.4 Jupiter masses, orbiting a K-type star every 9,883 years at a staggering 342 AU—over 300 times Earth’s distance from the Sun. Discovered via direct imaging in 2026 as part of the KOINTREAU survey targeting young stars in Taurus, its extreme separation suggests formation via disk […]

HD 164604 c

HD 164604 c is a massive gas giant exoplanet, weighing about 9.5 Jupiter masses (over 3,000 Earth masses), orbiting a K-type star every 14.8 years at around 5.6 AU. Far beyond the habitable zone, its cold environment rules out liquid water, but it joins an inner giant sibling, suggesting a dynamic system with possible gravitational […]

GJ 887 d

GJ 887 d is a Neptune-like exoplanet with a mass over 6 Earths, orbiting a nearby red dwarf every 50.8 days at 0.212 AU. Positioned near the inner edge of the habitable zone, its equilibrium temperature around 250-300K could support liquid water with a thick atmosphere, though its gaseous nature likely precludes rocky surfaces. Confirmed […]

TOI-4507 b

Discovered in 2025, TOI-4507 b is a Neptune-like super-puff exoplanet orbiting a young F-type star (700 million years old) every 104.6 days at 0.456 AU. With a mass of 20-30 Earth masses and radius of 0.73 Jupiter radii (about 8.2 Earth radii), its density is remarkably low at around 0.3 g/cm³, challenging planetary formation theories. […]

PSO J318.5-22

PSO J318.5-22, discovered in 2013 by Pan-STARRS, is a rogue gas giant ~6 times Jupiter’s mass floating alone in space—no orbit around any star. Formed like a planet but ejected from its system, it glows from leftover heat (1,200°F/650°C surface). No habitable zone without a star, but its auroras might light up like Jupiter’s. This […]
