Gas Giant
HD 189733 b has extreme temperature differences between its day and night sides (~650°C dark side to ~930°C sunlit side) and displays a distinctive blue color. This hostile world experiences some of the most violent weather in the known universe.
May rain molten glass sideways in howling winds. The blue color comes from silicate particles in the atmosphere that scatter blue light!
Super-Earth
Since 55 Cancri e orbits its star incredibly quickly (just 18 hours!), scientists believe that its surface is covered with oceans of molten lava. This super-Earth is larger than our planet but smaller than gas giants.
It takes just 18 hours to orbit its star fully! That means a "year" on this planet is shorter than a day on Earth. Imagine celebrating your birthday every 18 hours!
Gas Giant
Kepler-16b orbits two stars in a binary system, making it a real-life version of Tatooine from Star Wars! Despite the complex gravitational forces, it maintains a stable orbit around both suns.
It has 2 sunsets! From this planet's surface, you would see two suns setting at different times, just like Luke Skywalker's view from Tatooine in Star Wars!
Gas Giant
TrES-2b is the darkest exoplanet ever discovered, reflecting less than 1% of the light that hits it. This makes it darker than coal or even black acrylic paint! The extreme darkness is still a mystery to scientists.
TrES-2b is darker than coal! It absorbs 99% of light that hits it, making it nearly invisible. Scientists think exotic atmospheric chemistry causes this extreme darkness.
