This planet, called TrES-2b, only reflects about 1% of light that hits it, and is located extremely close to its star, and that's not all. Since it's located so close to its star, it is tidally locked. This means that on one side of the planet, it's always night.

Extremely rich and water, and known as a "super-Earth" due to it being larger than Earth but has a mass and radius significantly less than those of the gas giants in the Solar System. But, the water on Gliese 1214b is definitely not something that you would want to be drinking, as the pressure and temperatures keep this water in a plasma state, meaning that it has basically become electrically charged gas. All of this falls to the bottom of the atmosphere to create a deadly "ocean" of sorts, becoming a pressure cooker, you could say.

PSO J318.5-22 is definitely a strange planet. This is because it is known as a "free-floating planet". Rather than a star or brown dwarf, it orbits the galaxy. Some have proposed it to be a failed star, while the International Astronomy Union has proposed to call is a sub-brown dwarf, meaning that it was formed the same way as a star or brown dwarf, but mass below the amount of mass that limits the thermonuclear fusion of deuterium, which is how a star or brown dwarf form.

The reason that this planet is strange, is because it speeds up and slows down its orbit around its sun. This is due to the fact that there is an "invisible planet" that is continually pulling on Kepler-19b, and this leads to the phenomenon of it speeding up, and slowing down.

In the picture shown above, HD 189733b is shown passing in front of its parent star. This is the first Exoplanet to do so. However, due to how close it is, bad things may occur. A great example of this happened to HD 189733b. The parent star unleashed an extremely powerful flare, and HD 189733b did not fare well. Massive quantities of hydrogen blast from the exoplanetary atmosphere were discovered by Hubble.

The main problem with this planet, is that it may or may not exist. Studies have shown that the movements it has made are conflicting with the idea of it being an Exoplanet. Scientists have also discovered that sometimes it drifts off into the dust surrounding it. I just thought it looked very cool.
