With an estimated age of 13 billion years, the planet is twice as old as Earth's 4.5 billion years. It's as old as a planet can be, in that it formed around a young Sun-like star just 1 billion years after the birth of our universe in the Big Bang , the ancient planet having a remarkable history because resides in an unlikely and difficult area. It orbits a peculiar pair of stars burned into the crowded core of a cluster of more than 100,000 stars.

#15 Kepler-438b – The most Earth-like planet in terms of radius and mass.

Kepler-438b has an Earth Similarity Index (ESI) of 0.88, the highest known for a confirmed exoplanet to date, making it currently the most Earth-like planet in terms of radius and mass. The planet was announced as orbiting within the habitable zone of Kepler-438, a region where liquid water could exist on the planet's surface.

#16 Wasp-17b – Moving in the opposite direction

WASP-17b is one of the largest exoplanets discovered and contains at least half the mass of Jupiter. What is most interesting about this planet is that it retrogrades its orbit, which means that this planet moves in the opposite direction of its parent star.

#17 Tres-2b – Darker than charcoal

Being one of the darkest known exoplanets, it reflects less than 1% of any light that hits it (less than coal, for example). And the reflected light is slightly red, which gives the planet an evil red color.

#18 Hd 106906 – Your Formation Remains a Mystery

Being an exoplanet located 300 light-years from Earth in the constellation Crux . It orbits its star at a distance of 60 billion miles (approximately 96 billion kilometers), which is 20 times the distance between the Sun and Neptune, estimated to be about eleven times the mass of Jupiter, and it is unknown how. this planet formed or how it came to orbit so far away from its star.

Despite being so far from the heat of its star, this gas giant still has a scorching surface temperature of 1500 °C (2732 °F) and still glows in the infrared spectrum from the residual heat left over from its formation.

Hangurand A lava planet

Being similar to our planet Earth. This exoplanet is in the constellation Cygnua , in which the strangest thing about it, though, is how close it is to its host star: it's only 885,139 kilometers away, it's 40 times closer to its star than Mercury is. of the Sun and its temperature is estimated to be around 2030 °C (3680 °F), even though the planet may be the size of Earth, but “it can be imagined as a lava planet rather than a planet similar to the Sun”. Earth".

Fabur Being a rocky planet, but it is so close to the parent star that its surface is melted. To give you an idea, it is 23 times closer to the sun itself than Mercury is to ours, in which this distant 480 light-years from Earth, temperatures there can reach 2,200 degrees Celsius, enough to vaporize rocks. To complete the somewhat infernal scenario, imagine the possibility of a shower of stones and countless volcanoes erupting.

Composed of an unknown substance, Trisalis , B2 is darker than the blackest coals you've ever seen: it reflects less than one percent of the light it receives. According to the researchers, this gas giant 750 light-years from us may have in its atmosphere some chemical elements that absorb light, but even so, its blackness remains a mystery.

In which its system is composed of three suns - one yellow, one orange and one red, as if we were on a moon of this planet, since it is a gas giant, and the formation of planets will take a lot of work to explain How was it possible for a star like this to appear in the midst of three gravitational fields , in which you would travel 149 light years to enjoy a triple sunset?

It is the planet Adanur , on which and is marked for death: it will be devoured by the parent star itself "only" 10 million years from now, even though it is so close to the sun that its atmosphere is evaporating, and the lost material is consumed by the star, located 600 light-years from Earth, and it takes only a year there, lasting little more than an Earth day.

Demosthenes ( STScl ))

PSBR B1620-26 b was given the nickname Methuselah because of its longevity: it is 12.7 billion years old (the Earth is about 4.5 billion, and the Universe is 13.7 billion), that is, the ancient planet formed shortly after the Big Bang .

With its discovery showing that the planets of that galaxy that could support life may have appeared much earlier than we thought, with few of the Methuselah system being 5,600 light-years from Earth, and orbiting a binary system composed of a pulsar and a white dwarf.

Believe it or not, if there was a bathtub big enough, the HAT-P-1b would float in it. Situated 450 light-years from here, where its density is one-quarter the density of water, it is less than that of a cork, where it is about half the mass of Jupiter but nearly twice as massive as Jupiter. than our neighbor, where that includes it in a category of bloated planets, which also defy existing theories.

Imagine if every time you went to sleep, a year passed, on the planet SWEEPS-10 it's like this: every ten hours, a new year. Mercury, which is the closest planet to our sun, takes 88 days to orbit it, in which SWEEPS-10 belongs to a new class of exoplanets, characterized by "ultra-short-periods", which last less than an Earth day.

Located more than 20,000 light-years from Earth, close to the center of the Milky Way, rocky OGLE-2005-BLG-390Lb is a far cry from its parent star, a red dwarf. For this reason, the temperature on its surface is estimated to reach minus 220 degrees Celsius. Under these conditions, substances such as ammonia and methane, which for us are common in the liquid state, can appear in the solid state.

Tsuki traveled through some galaxies when he could see that some worlds were experiencing difficulties, with the provenance that it was even more difficult to find habitable worlds.

What wouldn't a human being do for an entire diamond planet? Orbiting the pulsar PSR J1719-1438, the huge gemstone was formed due to the very high pressure to which it is subjected (the pulsar performs 10 thousand rotations per minute) .

If it weren't for the fact that some worlds couldn't inhabit life, where they couldn't be inhabited, what use was it to rain diamonds since they were rains that cut the flesh, where life could be cut, if those who survive were turned into diamonds.

At that time when, under these conditions, carbon crystallizes, forming diamond, if we ever want to get there, we will have to travel 4,000 light-years, but we have no way of getting in, due to atmospheric pressure.

We know that planets revolve around their host star or stars, but is there any planet without its host star? Then we should name 2MASS J2126-8140 which is situated in the constellation of Octans .

Well, this exoplanet is not exactly without a host star, its host star being a red dwarf star that is 965 billion kilometers away from the exoplanet, in which it has the longest and widest orbit for an object of known planetary mass, in which to find such a low-mass object so far from its parent star, in what was a solar system, from a large disk of dust and gas, which is totally toxic.

Even though the problems would come through space, but no one knew where it really came from, the following happened.

Since the beginning of space exploration and colonization through space, there have been space migrations, towards various planets in space.

This happened due to globalization, fraternization and the free right to come and go through the stars, such as the free exit towards space, then, there was the emergence of a space strain that had one of the patients that soon spread through all these galaxies and the space outside.

The Missouri patient was hospitalized and diagnosed with primary amoebic meningoencephalitis, a rare and usually fatal infection, the disease causing inflammation of the meninges of the brain and spinal cord, but spreading too quickly due to the mutations, then, they saw that above all, they were the carriers of contagious diseases.
