5 Terrifying Planets You Don’t Want To Visit

Some 3,500 exoplanets —planets that orbit stars other than our own Sun— have been discovered since the first confirmed sighting in 1995. Of the planets discovered beyond our solar system, here are five of the most extreme:

WASP-12b – The incinerator
Located at a distance of 871 light years, it is the hottest known planet in the Milky Way galaxy. WASP-12b is 40 percent more massive than Jupiter and it’s so close to its star (about 2.1 million miles) that it takes little over 24 Earth hours to complete one revolution around the star. By contrast, Earth is about 93 million miles from the sun. Because of its sheer closeness and the extreme tidal forces it experiences because of its host star, WASP-12b exoplanet has a surface temperature of 2,200˚C. To put it in perspective, the planets’ surface is about half the temperature of the surface of our sun and twice as hot as lava. It goes without saying that anyone stepping on the planet will be incinerated in a flash.  But the planet has very short life span. WASP-12b is losing mass to its host star at an alarming rate.  Scientists at NASA estimate that the planet has about 10 million years left before it is completely eaten up but its host star.

COROT exo-3b - The crusher
What’s bizarre about this planet is that it has about the same size of Jupiter, but has 21.6 times Jupiter’s mass. That makes it denser than lead. The degree of pressure put upon a human walking the surface of such a planet would be insurmountable—you will weigh almost 50 times what you weigh on Earth. This amount of stress would crush a human beings skeletal system almost instantly.  Though scientists have not ruled out that the COROT-exo-3b may be a brown dwarf, or failed star. Brown dwarfs burn lithium but are not massive enough to generate the thermonuclear fusion of hydrogen and helium that powers real stars. Planets do none of that. 

OGLE-2005-BLG-390Lb –  The Freezer
This planet, with an unglamorous name, orbits a red star five times less massive than the Sun and located at a distance of about 20,000 light years, not far from the centre of our Milky Way galaxy.  Its relatively cool parent star and large orbit implies that the likely surface temperature of the planet is 220 degrees Centigrade below zero, too cold for liquid water.  The planet is estimated to be about five times Earth's mass. Though the planet is not so much notable for its size or possible composition—but for the fact that such a relatively small exoplanet was detected at such a relatively large distance from its star. Prior to this, "small" exoplanets were detected very close to their stars.

51 Pegasi b - A relentless rain of molten iron
In 1995 astronomers announced that they had discovered a planet, 51 Pegasi B, in orbit around its star, 51 Pegasi — the first exoplanet found orbiting a star similar to the Sun.  Nick-named Bellerophon, in honor of the Greek hero who tamed the winged horse Pegasus, this gas giant is over 150 times as massive as earth and made mostly of hydrogen and helium.  The problem is that Bellerophon roasts in the light of its star at over 1800 degrees F (1000 degrees C). Bellerophon’s star is over 100 times closer to it than the Sun is to Earth. And here is the icing on the cake: Scientists believe that clouds on this planet rain a relentless fury of molten iron. 
 
PSR J1719-1438 b –  An assault of  X-rays and gamma rays
PSR J1719-1438 is the densest planet ever discovered. It’s most likely composed largely of crystalline carbon, but with a density far greater than diamond.  Here is how it’s dangerous:  The planet orbits a millisecond pulsar – rapidly rotating neutron stars – which spins on itself every 5.8 milliseconds and emits strong magnetic field. Scientists say that these fields will lead to the emission of a vast amount of X-rays and gamma rays that would kill any living being foolish enough to get close.

What's your take on these "extreme planets? And are we ever going to live in them ? Please share with us your views.

Snehil Verma NATIONAL CENTRE FOR EXCELLENCETIPPS

So are all these proven.. or have the scientists assumed the planets to have this potential.. if it is real then its truly fascinating.

NAVYA MALHOTRA SWARAJ INDIA PUBLIC SCHOOL

These planets are intriguing ....even if we have to go to another planet , we would find planets with a habitable atmosphere...I don''t think we would ever go.....surely research work will continue

Ritvik Baweja Bal Bharati Public School

It''s no point of going to these planets now without any proper evidence reports but yes due to the rapid developments in the field of technology and space travel one day would definitely come when achieving this feat would be possible.

Hargun Kochhar GYAN BHARTI SCHOOL(SAKET)

Omg! do these planets really exist.....so fascinating ,we for sure will never have to go to these planets.

Vaasu Bisht DPS Indirapuram

There planets are great place to explore but with present technology its impossible to visit sure planets, but i am sure that future technology will make exploration more easy and we will be able to visit such terrifying planets.

Aryan Erry DAV SCHOOL (GURGAON_14)

All these planets are just a small part of the vast universe. These terrifying exo-worlds are just the ones which top astronomers have detected in our galaxy. Who knows, there maybe more planets like this or even more terrifying ones

The Times of India Student edition, a customized student newspaper exclusively for the students, packs a powerful punch in terms of content that leads to a smarter and superior learning experience. The information is crafted such that it finds use in classroom discussions, thus making it relevant and current. It truly gives education a new dimension by fostering the simple habit of reading which in turn paves the way for a confident, informed and aware individual.

On a significant scale Times NIE comprises diverse interesting activities and events that boost the child’s passion for learning, while revealing hidden talent.

While you are aware that The Times of India is among the leading English Newspapers across the world, it has consummated its position as an everlasting winner. With several international awards and recognitions to its credit, The Times of India and Times NIE have validated an enduring tradition of setting the highest benchmarks in every respect. We have been awarded with the two most prestigious awards, Times NIE - World’s No.1 NIE program and The Times of India, Student Edition - World’s No.1 Newspaper for the youth in 2006 by the celebrated World Association of Newspapers (WAN). In 2008 we were honoured by the International Newspaper Marketing Association (INMA), yet another international recognition for ‘Youth Audience Development’. In 2013 we were again honoured by the celebrated World Association of Newspapers (WAN) as the ‘Times NIE - World’s Best Youth Engagement Program’.

Times NIE has grown remarkably over the last three and a half decades, touching millions of children across more than 16 Indian cities. Our absolute commitment towards the fledgling generation remains undiluted and our greatest strength lies in the school partnership and commitment.
