10 Dangerous Planet in the Universe
- SciTechDaily
It is located in the direction of the Sagittarius constellation and is about 4,800 light-years away from Earth.
On this planet, you get all the fun of toxic gases, and extreme winds of a gas planet combined with the high temperatures of Mercury or Venus. What you get is a planet where it literally rains liquid, melting iron.
6. Upsilon Andromeda b
Upsilon Andromedae b is one strange exoplanet that rotates around the star Upsilon Andromedae A, which is 44 light-years away from Earth. The exoplanet is too close to its sun, completing an orbit in just 4.6 days
Here's a theory about the planet Upsilon Andromeda b:
The heat from the star Upsilon Andromedae hits the side of exoplanet Upsilon Andromedae b that is facing the sun, causing the air to heat up. When that air becomes hot enough, the wind transports it to the opposite end of the exoplanet.
At the same time, the wind transports the cooler air at the opposite end to the side facing the sun. Then the process continues. The continuous switch means that the side shielded from the sun has a reliable flow of hot air while the side facing the sun has much cooler air
7. WASP-121b
WASP-121b is one weird exoplanet. To begin, it is not spherical but looks more like a football. The shape is not what makes WASP-121b deadly.
Instead, the problem is the exoplanet’s nearness to its star. WASP-121b is so close to its star that temperatures hover around 2,540 degrees Celsius (4,600 °F). Solid or liquid objects cannot form there, and everything just remains in a gaseous state.
This includes its metallic atmosphere, which is filled with iron and magnesium gases. Worse, the exoplanet is losing this atmosphere to its star, just like KELT-9b.
Curiously, the closeness to its star is the same reason that WASP-121b is stretching out of shape. The star is able to exert a heavy gravitational pull on the exoplanet. WASP-121b cannot resist the pull because it has a weak gravitational force. It manages to partly resist, though, causing it to bend out of shape
