GJ 504b - TOP 10 SPECIAL EXPOPLANETS

10 Special Exoplanets

It’s fascinating times for astronomers. In 2009, NASA sent the Kepler Space Observatory space. This satellite studies from a track around the Earth our Milky Way, sending masses of distant stars and planets to astronomers. Already more than 2,000 so-called exoplanets (planets that rotate around a star than our sun) have already been studied. The exoplanets all got a number. There are strange guys between those exoplanets, and some of them were dealt with with an appropriate nickname. Below is a list of 10 special celestial bodies.

The pink planet

Exoplanet GJ 504b is a pink planet, which is still nagged by the heat of its origin. The pink planet is not only pink, it is also very big. GJ 504b has about the volume of Jupiter, but it weighs four times more. A pink cozy thicker among the exoplanets thus.

Metusalem, the oldest among the exoplanets

Metusalem - TOP 10 SPECIAL EXPOPLANETS

Exoplaneet PSR 1620-26b, also called Metusalem (according to the Bible he was 969 years old), is the oldest known planet in the Milky Way. Observations show that this exoplanet is no less than 13 billion years old. Compared to Metusalem, our own earth, which is “only” 4.5 billion years old, is another teenager. Metusalem originated “almost” one billion years after the creation of the universe, the so-called Big Bang. To visit Metusalem you need to spend 12,400 light years on the zodiac sign Scorpio.

The diamond planet

Exoplaneet 55 Cancri e - TOP 10 SPECIAL EXPOPLANETS

A planet that consists almost entirely of diamond? Yes, she exists! You must travel to the zodiac sign Cancer. Exoplanet 55 Cancri-e is about twice as big as our planet. Diamond digging on this exoplanet is not a good idea, given its surface temperature of over 2,000 degrees Celsius. The diamond planet moves at incredible speed around her sun. In only 18 hours time there is 55 years left at 55 Cancri-e!Also nice to mention, this planet has been given the official name “Janssen”, to Dutch optician Zacharias Janssen, often referred to as the telescope inventor .

The fastest planet

PSR J1719 14b - TOP 10 SPECIAL EXPOPLANETS

However, the greatest speed devil among the exoplanets is number PSR J1719-14b. Exoplanet PSR J1719-14-b revolves around a so-called pulsar. That is a rotating neutron star, which we observe the radiation on earth as fast pulses of light. The exoplanet moves so fast around the pulsar that takes one year on PSR J1719-14b only two hours. A great job to keep your birthdays on this planet …

The darkest exoplanet

Why Tres-2b is so dark, scientists are not out of date. The exoplanet is heavier than cabbage, and reflects almost no light from the stars nearby. Astronomers agree that this is the darkest planet discovered so far. Tres-2b is a giant planet that is about the same size as Jupiter. On her surface, it’s about 1000 degrees hot – not really an environment to spend your vacation!

Waterworld

GJ 1214b - TOP 10 SPECIAL EXPOPLANETS

Water sports enthusiasts would get their heart on exoplanet GJ 1214b, nicknamed ‘Waterworld’. This exoplanet is larger than the earth and has its own atmosphere. According to observations, number GJ 1214b would consist of 75% water. The planet could be an ocean planet whose surface is completely covered with water. Unfortunately, for the time being, you will not be able to spend your vacation on Waterworld with your swimsuit and surfboard. The exoplanet is in the zodiac sign Snake carrier, on a messy 40 light year of our solar system.

The giant among the exoplanets

WASP 17b - TOP 10 SPECIAL EXPOPLANETS

In the constellation Scorpio you can hardly look next to the WASP-17b giant exoplanet set. The diameter of this giant is twice the diameter of Jupiter and 22 times greater than the diameter of the earth. So far, it is the largest known exoplanet. It is striking that the mass of the exoplanet is less than half the mass of Jupiter. Thus, the WASP-17b must be a very “inflated” planet, consisting mainly of gas.The WASP-17b is not only washed out of the bumps but also in the opposite direction. The exoplanet follows a retrograde job around her star: her movement is opposed to the swing of her sun.

The coldest exoplanet

OGLE 2005 BLG 390Lb - TOP 10 SPECIAL EXPOPLANETS

Whoever likes to keep cool, may feel at home on the OGLE-2005-BLG-390Lb exoplanet. Although, a surface temperature of -220 ° C can not be called directly. This exoplanet is the coldest astronomers discovered to date. Looking for life on OGLE-2005-BLG-390Lb makes little sense, because at such a temperature even the toughest form of life keeps it looking. The coldest exoplanet is located in the zodiac sign Sagittarius, in 20000 light years of the earth.

The Apocalypse survived

V391 Pegasi planet 1 - TOP 10 SPECIAL EXPOPLANETS

A remarkable exoplanet set is V391 Pegasi-b in the constellation Pegasus. This exoplanet revolves around a star that has evolved into a ‘red giant’. A star swells at the end of her life into a so-called red giant, with her volume increasing hundreds of times. Our fate is also awaiting this fate. When our sun becomes a red giant, she will “sluice” the planets Mercury and Venus. The surface of our earth will deteriorate and all water in the oceans will evaporate. V391 Pegasi-b is an example of an exoplanet that survived this Apocalypse. At least, the planet itself has survived. Any life forms did not seem to be a chance. Do not worry, our own sun will definitely last for five billion years …

Kepler-452b: the older cousin of the earth

Kepler 452b - TOP 10 SPECIAL EXPOPLANETS

In 2015, astronomers in the constellation of Zwaan discovered the Kepler-452b exoplanet network. It is an exoplanet where liquid water can be found on the surface, an important condition for the emergence of life. Kepler-452b is a bit bigger than the Earth and has a 385-day turnaround around her star. This star is 1.5 billion years older than our sun. Exoplanet-452b could thus continue for an older cousin of our planet. Researchers are very interested in Kepler-452b. After all, an older cousin can raise something. The evolution of the remote exoplanet can teach us a lot about the future that our own globe is waiting for.
