There is one known planet orbiting HAT-P-67A. HAT-P-67b is a gas giant planet transiting its parent star every 4.8 days, at an orbital distance of 0.065 astronomical units (9,700,000 km). It is one of the largest and lowest density planets known as of 2024. [7] [8] Transit light curve of HAT-P-67b [5]
HAT-P-38b is a hot Saturn that takes over 4 days to circle its host star in a relatively circular and tight orbit; it has a separation of 0.0519 astronomical units. HAT-P-38b has 26.6% the mass of Jupiter, which is similar to that of Saturn. However, tidal heating from HAT-P-38 causes the planet to bloat to 82.5% the radius of Jupiter.
The sizes are listed in units of Jupiter radii (R J, 71 492 km).This list is designed to include all planets that are larger than 1.6 times the size of Jupiter.Some well-known planets that are smaller than 1.6 R J (17.93 R 🜨 or 114 387.2 km) have been included for the sake of comparison.
The distance separating the planet and its star is just 7% of the distance between Earth and the Sun, and the planet receives 1.6 times more energy from its star than Earth does from the Sun.
HD 149026 b was the first of its kind: [20] HD 149026 b's low volume means that the planet is too dense for a Saturn-like gas giant of its mass and temperature. It may have an exceptionally large core composed of " metals ", or elements heavier than hydrogen and helium: [ 1 ] the initial theoretical models gave the core a mass of 70 times Earth ...
HAT-P-7b (or Kepler-2b) is an extrasolar planet discovered in 2008. It orbits very close to its host star and is larger and more massive than Jupiter. Due to the extreme heat that it receives from its star, the dayside temperature is predicted to be 2,630–2,880 K (4,270–4,720 °F; 2,360–2,610 °C), while nightside temperatures are 2,211–2,238 K (3,520–3,569 °F; 1,938–1,965 °C).

HD 189733 b is an exoplanet in the constellation of Vulpecula approximately 64.5 light-years (19.8 parsecs) away [7] from the Solar System.Astronomers in France discovered the planet orbiting the star HD 189733 on October 5, 2005, by observing its transit across the star's face. [1]
HAT-P-6 also named Sterrennacht [10] is a star in the constellation Andromeda, located approximately 895 light years or 274 parsecs away from the Earth. It is an F-type star, implying that it is hotter and more massive than the Sun. The apparent magnitude of the star is +10.54, which means that it can only be visible through the telescope.
