Gliese 581: Maybe living

This planet is located in Libra, 20 light-years from Earth. Because it is locked by its tidal tide, it is always hot and the other side is always cold. However, between the two hemispheres, there is a long and narrow area that theoretically allows life to exist.

J1407b: Super Saturn

Located 434 light years from Earth, it is located in Centaur. Its large star ring is about 640 times the diameter of Saturn’s ring. If it is in Saturn’s current position, its star ring will occupy the earth’s sky.

Gj 1214b: Water World

No land, the ocean is spread over the entire surface, a bit like the larger and hotter version of Europa

Gliese 436b: Planets that violate the laws of physics

30 light years from Earth, located in Leo. It seems to violate the laws of physics, and although the surface temperature reaches 439 ° C, there is still ice. It turns out that its gravity is so strong that it can keep traces of water vapor in the planet’s atmosphere in the form of solid ice.

Wasp-12b: Planet that devours light

One of the darkest exoplanets known, which is twice the size of Jupiter, is a gas giant that looks as black as charcoal because it captures at least 94% of the visible light entering the atmosphere. Because it is very close to its star, the surface temperature exceeds 2000 ° C

55 Cancri E: Diamond Planet

It comes from Cancer, which is only 40 light-years away, twice the size of the Earth, and nearly 8 times the mass. Due to the pressure and average maximum surface temperature of 2400 ° C, its surface may be covered with diamonds

Hat-P-7b: Planet with a gem rain

Located in Cygnus, about 1000 light years from Earth. Highly precipitated alumina (corundum) is found in the atmosphere, including rubies and sapphires, so one can speculate that the weather on this planet is “with ruby ​​and sapphire rain”

Hd 189733b: Planet under the glass rain

Slightly larger than Jupiter, about 62 light years from Earth, it has a deep and beautiful azure blue, the atmosphere is mainly composed of silicate atoms and particles, and the storm is full of glass. The surface temperature of the planet exceeds 900 ° C, and the wind speed can reach 2 km per second (7 times the speed of sound)

Psr J1719-1483 B: It used to be a star

The planet orbits a pulsar (and possibly a very dense neutron star). It used to be a white dwarf, but it is too close to the main star and loses most of its residual material. Carbon crystallization occurs in an ultra-high gravitational pressure environment, and the fusion reaction stops completely. The classification thus changes from a star to a planet. It is only 19 kilometers in diameter and has a mass of 1.4 times the mass of the sun.

Ogle-2005-Blg-390lb: Frozen Wasteland

Outside the 20000 light year, a red dwarf star runs around Sagittarius. Because it is too far away from the star, its surface temperature is only -220 ° C, covered with thick ice, and there is no life. But there is still a warm core below the surface.

Gj-504b: Pink Planet

This beautiful pink (or magenta) planet is located in Virgo. It is a newly formed planet that still emits heat

Kepler-10c: Giant Earth

Located 560 light years from Earth, in the Dragon, it is a planet with 17 times the weight of the Earth, more than twice the size, running around a planet like the sun. Scientists call it “Giant Earth”

Psr B1620-26 B: Almost as old as the universe

Founded 13 billion years ago, less than a billion years after the Big Bang, this ancient planet has an extraordinary history because it is surrounded by a special energy in a crowded area of ​​more than 100,000 stars. Stellar operation

Tres-2b: darker than coal

It was identified as the darkest exoplanet in 2011, reflecting less than 1% of light (lower than coal). And the light it reflects is dark red, it looks very evil

Tres-4b: Puffy Planet

Located in Hercules, 1400 light years from Earth, it is one of the largest exoplanets ever discovered (1.7 times Jupiter), but because of its extremely low density, it is classified as a “puffy” planet.

Hd 106906: Its formation is still a mystery

300 light-years from Earth, 96 billion kilometers away from the stars (20 times the distance between the Sun and Neptune), the mass is about 11 times that of Jupiter, I don’t know how it was formed. Although it is far from the star, it is still full of natural gas, so its surface temperature is still as high as 1500 ° C

Kepler-78b: Lava Planet

Located in the Swan Constellation, it is about the size of the Earth and has a rocky surface. However, it is only 885139 kilometers away from the star, and its surface temperature reaches 2030 °C, thus becoming a lava planet.

Kepler-438b: The most earth-like planet

At 470 light years from Earth, the Earth Similarity Index (ESI) is 0.88, which is the highest value of exoplanet to date. It operates in the livable area of ​​its star, and liquid water may exist on the surface.

Wasp-17b: reverse motion

About half the mass of Jupiter. More interestingly, it is the first planet to be discovered in retrograde orbit, that is, the direction of the planet’s revolution is opposite to the direction of the rotation of its own star. This is a strange phenomenon that is difficult to explain in the current theory.

2mass J2126-8140: The most lonely planet

The planets orbit around the main star or star, but there may be planets without any main stars. This planet in the Antarctic seems to fit this feature. After research, it is not completely without a main star, but is running around a red dwarf 965 billion kilometers away. This is the longest and widest orbit of the known planet. It is a revolution and requires almost 1 million Earth years.
