The 3 Most Mind-Bending Planets You've Never Heard Of

Blood Brother is no stranger when it comes to extracting inspiration from science, space-time, and mankind's everlasting yearn for answers to life and what lays beyond our solar system.

We decided to compile a short list of some of the weirdest planets we know of, and their atmospheric behaviour.


It's raining rocks!

COROT-7b is a rocky exoplanet which orbits VERY close to its host star. It's 489 light years away from Earth, and actually has the shortest orbital period on record of any planet with 20 hours. Temperatures on the side of daylight run up to 2600ºc, which is more than enough to not only make the rocks melt, but then also evaporate them into the air where they become actual clouds of rock. At the same time, the nighttime side of the planet cools down to about 1800ºc, and this is where it gets mental.

Once daylight passes and the clouds of rock are now on the cool side of the planet, they start raining magma. The magma-rain cools down during the falling process and before it hits the ground becomes rock. Yes rock. Rock-rain is a thing. The rock-rain hits the ground where it rests until it gets melted again the next day and this cycle repeats itself indefinitely.


HD 189773-b
The most aggressive atmosphere ever

This illustration shows HD 189733b, a huge gas giant that orbits very close to its host star HD 189733. The planet's atmosphere is scorching with a temperature of over 1000 degrees Celsius, and it rains glass, sideways, in howling 7000 kilometre-per-hour winds. At a distance of 63 light-years from us, this turbulent alien world is one of the nearest exoplanets to Earth that can be seen crossing the face of its star. By observing this planet before, during, and after it disappeared behind its host star during orbit, astronomers were able to deduce that HD 189733b is a deep, azure blue — reminiscent of Earth's colour as seen from space.

HD 189773-b is a beautiful exoplanet slightly larger than Jupiter located 63 light years from us. The blue and white ripply appearance of the planet is due to the fact that it's mostly made up of silicate particles. Imagine rain made of sand or glass... And it rains at 930ºc.  Oh did I mention the winds there reach up to 5,400mph? That's 7 times faster than the speed of sound.

Essentially stepping foot on this planet would be instant death by millions of tiny pieces of 930º glass blowing through your body simultaneously, at the speed of a mile a second.

Just for some context, if the same storm occurred here on Earth at the same wind speed, the storm would travel round the whole world in 5 hours, completely wiping out everything in its path along the way.

HD 131399Ab
What's better than one sun? Three


This new finding discovered in July 2016 broke a bunch of records. HD 131399Ab revolves around 3 suns at once, is 4 times larger than Jupiter and hangs out 340 light years from Earth. It also boasts an unusually long orbit time, one year revolution of the exoplanet around its 3 suns takes 550 of our Earth years. On top of that, as the planet spins quite slowly, the 3 suns only descend from the sky in about half of this time, meaning a sunset would only typically occur once every 225 years.

As this is still a new finding, information of the planet's characteristics are somewhat scarce. Although we estimate the planet to be about 16 million years old, and the temperature to be around 577ºc, making it one of the coldest exoplanets on record.

The coolest part about this planet requires imagination. Every 100-140 years, all 3 suns are visible on a single day creating possibly one of the most beautiful skylines in the known universe. And you'd have 3 shadows!


I just wish we had 3 moons. Imagine.
