Jakarta – Along with the advancement of science and technology, the existence of celestial objects in outer space has never stopped being researched. Including presence planet other than Earth in the solar system.
One of the discoveries by astronomers is the number of exoplanets or planets outside our Solar System. However, not to be inhabited, the planet found is actually a terrible planet. What are the planets in question?
9 Terrible Planets Astronomers Found:
1. Planet TOI-1431b atau MASCARA-5b

This planet is 490 light years from Earth. Why is it called terrible? Because this is one of the hottest planets ever discovered.
The temperature during the day reaches 2,700 degrees Celsius, and at night 2,300 degrees Celsius. So hot, metal can evaporate on the planet.
2. Planet HD 189733 b
The gas planet found by this astronomer is called terrible because its temperature during the day can reach 965 degrees Celsius.
Even the most extreme, on this planet is the presence of winds that can blow at a speed of 7,242 km / h, or six times the speed of sound.
3. Planet HD 209458 b

The name is similar to the previous planet, but this planet has many components that can support life such as water, water vapor, methane, and carbon dioxide.
Even so, this planet is very dangerous for life because it is so close to its star that its atmosphere boils.
4. Planet HD 149026b

In addition to the planet MASCARA-5b, there is one planet that was also found to be the hottest and densest planet. The planet is HD 149026b.
The heat on the surface of this planet can reach 2,037 degrees Celsius or three times hotter than the surface of Venus, which is the hottest planet in the solar system.
So hot, the planet absorbs all the heat from its star and can barely reflect light.
5. Planet Wasp-76b
this planet can be the hottest and coldest. Because it is so close to its star, the planet’s daytime temperature can reach 4,000 degrees Celsius, hot enough for metal to vaporize.
But on the other side which is always dark because it’s not facing the star, the temperature is 1,000 degrees cooler so the metal can condense and drip like rain.
6. Planet GJ 1214b
Unlike the others, this planet has a structure that is covered by water. But instead of getting colder, the planet has a hot surface ranging from 120 to 280 degrees Celsius. That’s because the planet is only 2 million km from its star.
7. Planet 55 Cancri e

Scientists and astronomers once thought the planet was filled with diamonds and graphite. But after research, it turns out that 55 Cancri e has a temperature of around 2,704 degrees Celsius. Beneath its thick atmosphere, the planet is thought to have a vast sea of lava.
8. Planet COROT-7b
This planet is said to be similar to the planet Earth because of its structure as a rocky planet. However, because it is rocky, the rain that falls on this exoplanet is in the form of small pebbles.
This is because its atmosphere is made up of the same materials as rock, including iron, silicon monoxide, sodium, and potassium.
9. Planet PSR B1257+12 b, c dan d

These three exoplanets are actually remnants of the solar system before the star PSR B1257+12 exploded and a supernova occurred. Now the star PSR B1257+12 emits a very strong beam of radiation that can be detected from Earth. This planet is known to be terrible because it is always bombarded with deadly radiation.
Well that’s 9 scary planet discovered by astronomers. Interesting isn’t it, detikers?
