In our entire solar system, the planet Venus is the most dangerous of all planets. The surface temperature of Venus has the potential to melt lead and turn it completely into liquid form. Venus is not the closest planet to the sun but still, it is the hottest planet in our solar system due to its thick atmosphere and runaway greenhouse effect. The acidic atmosphere of Venus is as thick as water. The atmospheric temperature of Venus is so strong that it can melt most metals used to make spacecraft.

Living on Venus would be very much similar to Hell on Earth. But, if Venus is the most dangerous planet in our solar system, What are the most dangerous exoplanets in the universe we have discovered so far?
5 Planet OGLE-TR-56 b
In 2002 planet OGLE-TR-56 b was discovered in the Sagittarius constellation, The distance of this planet from the Earth is about 5,000 light-years away. This dangerous planet was found to have moved too close to its own star to be hospitable to living organisms. It takes about 28 hours to complete one circle of its host star.
The Surface temperature of this fiery world reaches 1,650 degrees celsius. Planet OGLE-TR-56 b is about 1.4 times bigger than the largest planet in our solar system (Jupiter). This planet is located very close to its star so it is hotness creates rain showers of hot iron liquid falling to the surface.
4 Planet TrES-2b
The distance of planet TrES-2b from the Earth is about 750 light-years away, located in the Darco constellation. It is the darkest planet in the Darco constellation. It was discovered in 2006. The planet TrES-2b is similar to our largest planet Jupiter and its star also matches our Sun. The planet is so dark that its reflective power is less than the black acrylic paint.
Due to its extremely high temperature of more than 982 degrees celsius, it lacks reflective clouds. Its atmosphere has vaporized sodium, gaseous titanium oxide, or potassium-like light-absorbing chemicals. Even these light-absorbing chemicals cannot fully explain the extreme blackness of this fiery world. Moreover, it is not fully pitch black. The extreme hotness of this planet burns much like coal.
3 Planet KELT-9 b
The distance of this planet from the Earth is about 670 light-years, it is located in the Cygnus Constellation, identified as one of the hottest planets known. Its discovery was made in 2007 and is double the size of our Jupiter. The star of this planet is 3 times bigger and double hot as our sun.
The Planet KELT-9 b is so near to its star that it takes just 36 hours to complete an orbit. Its unimaginable daytime temperature reaches 4,315 degrees celsius. The extreme hotness of this planet allows its own hydrogen atmosphere to boil and escape toward its nearby star. Scientists think that at this rate, In 200 Earth years the planet will lose its entire atmosphere.
2 Planet Proxima B
Over 4 light-years away lie our closest-known extra-solar neighbor. The discovery of the planet Proxima b was made in 2016 and the size of this planet is almost the same as our Earth and lies right outside our solar system. Initially, scientists thought that the planet can support life after seeing orbiting the exoplanet in the habitable zone of its star.
Recently observed while releasing dangerous solar flares red dwarf, Proxima Centauri is the star of this exoplanet. Astronomers think that they have spotted the largest flare ever recorded from the star Proxima Centauri. The intensity of the solar flare was powerful that the Proxima Centauri became 14,000 times brighter within 10 seconds. And the star was blasted with dangerous and deadly radiation.
1 Planet OGLE-BLG-390Lb
On the back side of these hot planets, there is a cold rocky exoplanet at the center of our own galaxy with a very thin atmosphere. This frigid world was thought to support life, however, we now think that could not be far away from the truth. Its cold temperatures are as low as -220 degrees celsius. That is even not equal to the lowest temperature ever recorded here on Earth which is -98.7 degrees celsius.
Here in this frigid world liquid water can not exist. This planet is 5 times as massive as our Earth and orbits its host star in about 120 months. The universe is filled with combative planets that might not support life. In the near future, these hostile planets help us redefine life. While they seem unsupportive to us, these planets could be growing life that we have yet to understand.
