Top 5 Planets Too Dreadful to Visit
The mystery behind all planets has always captivated mankind and the discoveries to come will keep adding to our gathered knowledge of the cosmos.
There are some planets out there that are too dreadful to visit just in case man has the ability or the means to visit them. And so we are counting down the top 5 planets that are scary enough to keep you away.
1. Gliese 581c
A planet 20 light years from Earth and located in the direction of the constellation of Libra, Gliese 581c is theoretically the most likely to support colonization. It is most likely tidally locked, meaning one side of the planet is always facing its host star (a red dwarf) while the other side is in constant darkness. It is at such a distance that standing on the star side of the planet will completely melt you while the dark side will freeze you immediately.
Great, Gliese 581c is a planet that is hell on one side and a dark freezer on the other half.
2. HD 209458 b
Located 150 light years away from planet Earth in the Pegasus Constellation, HD 209458 b is the first exoplanet to be discovered in transit of its orbiting star. It is thirty percent larger than Jupiter while its orbit is 1/8 of Mercury distance from the sun. Naturally, its temperature is extremely high about 1832 degrees Fahrenheit.
This gas planet under the extreme heat and great pressure has faced evaporation of different atmospheric gasses that stream escape its gravitational field including hydrogen, carbon and oxygen so going into this exotic planet will kill you.
3. TRES-2b
The gas giant TrES-2b is the darkest planet ever found. TrES-2b orbits the star GSC 03549-02811, which is located about 750 light-years away in the direction of the constellation Draco. The planet orbits at a distance of about 3 million miles from its host star. Yet it is coal-black and does not reflect any light. Being less reflective than coal or the blackest acryllic paint makes it by far the darkest planet ever discovered. It would look like a near-black ball of gas with a red tinge to it.
TrES-2b star's intense light heats the planet to a temperature of more than 1,800° Fahrenheit - much too hot for ammonia clouds to form. Instead, its extreme atmosphere contains light-absorbing chemicals like vaporized sodium and potassium, or gaseous titanium oxide. But none of these chemicals can really prove the blackness of TrES-2b.
4. COROT-3b

COROT-3b is a planet 2200 light years away that orbits an F-type star in the constellation of Aquila. It is the most massive and densest exoplanet up-to-date. It is 21.66 times the size of Jupiter and about 25 times that planet's mass. This makes COROT-3b about as twice as dense as lead.
A human walking the surface of such a planet would be crushed because of the degree of pressure. With a mass 20 times that of Jupiter, a human would weigh almost 50 times what they weigh on Earth. And that can crush the skeletal system instantly.
5. WASP-12b
An exoplanet 871 light years away found within the constellation of Auriga, WASP-12b is a planet being slowly pulled apart by its mother star. It orbits so near the star that its tidal forces are stripping away its upper atmosphere at a rate of nearly two hundred quadrillion tons each year, turning it into a nearly egg-shaped ball of superheated carbon.
Leading astronomers suspect that deep below the turbulent shield, this giant planet might contain rocks made of diamond or graphite.

Very interesting! But if I think about the distances I wonder if "we" (or part of "us") will ever leave our own solar system ... Imagine that for example 871 light years away means that if we could watch this planet we would see things which did happen 871 years ago. :)
Yes, that is right.
@darthnava
Have you ever looked into the Flat Earth Theory?
Heard of it, but not sure.
This is such interesting information. I wonder on the first planet (Gliese 581c), would there be a belt of temperature where humans could actually survive? In between the intense heat and cold...
Maybe but it is only a theory.
