Astronomers have discovered many planets outside our solar system.
The planets are not only found, but also very interesting to be studied.
Of the many planets, there are some unique planets, lo. Let's see!
The Coldest Planet
The coldest planet ever found in the universe is the Planet OGLE-2005-BLG-390Lb.
This planet has a size of Earth and is considered the world of ice because the entire surface is covered by ice.
The temperature on this planet can reach minus 200 degrees Celsius, lo. How come?
Because the parent star is very small and can not provide heat to the planet.
The size of its parent star is 5 times smaller than the Sun.
The Biggest Planet
The largest planet in the universe is Planet 2MASS J08230313-4912012 b.
This planet has a size of 28.5 times larger than the planet Jupiter or about 313.5 times larger than Earth.
Well, that's great, yes! No wonder it is considered the largest planet.
The material of the planet is a gas, not a rock like Earth.
The planet is 67.7 light-years from Earth.
The Lightest Planet
Well, if the planet is the lightest Planet HAT-P-1.
The size of this gas planet is about half the planet Jupiter.
Although bigger than Earth, but it turns out the planet is very light, lo.
Even astronomers say if there is a big water in the universe, this planet can float and not drown.
The Planet with the Most Widespread Ring
There are several ringed planets found by astronomers in the universe.
But this one planet is unique, lo.
Named J1407b, the planet has a very large and sooooooo big ring.
Even the ring layer is bigger than the planet itself.
The width of the planet's ring is 200 times larger than that of Saturn.
The Most Hot Planet
Planet Kelt-9b is the hottest planet in the universe.
Needless to say again, this planet is definitely not habitable.
Because the temperature can reach about 4,300 degrees Celsius.
Even on the dark side the temperature is still hot, which is about 3,700 degrees Celsius.
This planet can be very hot because of the position of its parent star is very close.
Once orbiting, this planet takes only 1.5 days, compared with Earth that takes 365 days.
The Most Remote Planet of its Mother Star
Planet HD 106906b is the planet that has the most distant distance with its parent star.
Its distance to its star is about 90 billion kilometers or about 20 times farther than Neptune's distance to the Sun.
The size of the planet is also large, which is 11 times larger than the planet Jupiter.
Well, that's some of the unique planets that exist in the universe.
Cool to read all of this at one place! Thanks for share!
