|This is the Most Extreme Planet in the Universe|
Here what I mean by extreme planets are planets that have advantages that stand out and are different from the others, there are the hottest, coldest, oldest and youngest planets and many others. And on this occasion I will discuss about the most extreme planets in the universe outside our galaxy.
So what are the planets? Come with me, we'll find out!
Maybe we already know that Mercury is the hottest planet in our solar system, with temperatures reaching 430 degrees Celsius. But it turns out, Mercury is nothing compared to the planet KELT-9B. This planet is very large with a mass of 2.5 times the sun. Unfortunately, scientists have not been able to measure how far KELT-9B is from its parent star, due to difficulties and tool limitations.
What is clear, the average temperature on the planet is estimated at 4,300 degrees Celsius! The heat seemed unimaginable.
The Coldest Planet
We used to know that Pluto was often referred to as the coldest place. But Pluto is not the coldest planet ever. Planet OGLE-2005-BLG-390Lb or Planet OGLE is a planet orbiting a red dwarf star as its parent.
The planet, which is often referred to as Hoth, is a frozen planet with temperatures reaching -223 degrees Celsius. With such extreme temperatures, OGLE has no atmosphere because all layers of air freeze into ice. The size of this planet is almost the same as the earth, which is clear this planet is colder than your ex's heart.
When a star explodes, it can create a brown dwarf. The size of the brown dwarf itself is larger than the planet in general. DENIS-P J082303.1-91201b is a planet that is still being debated by scientists because of its very large size. The planet DENIS has a mass 28.5 times heavier than Jupiter and 9063 times heavier than Earth! that means this planet has a jumbo size and is very large.
There are the largest planets, of course there are the smallest. Kepler 37-b is the smallest planet ever discovered by NASA. It is smaller than Mercury but slightly larger than the Moon. The planet also orbits its parent star at a very close distance, closer than the distance between Mercury and the Sun. It is confirmed that this planet has a very hot temperature, so it is impossible to find water or life there.
The age of the universe is estimated at 13.8 billion years, only 1.1 billion years older than the planet PSR B1620-26b. Yes, this planet is the oldest planet in the universe so far. To be precise, the planet PSR is 12.7 billion years old. The planet is even older than its two parent stars, a neutron star and a white dwarf.
The youngest planet
V830 Tauri is an imperfect planetary system. He is only 2 million years old. The parent star of this planetary system is the same size as the Sun, but has not yet fully formed. In the next few million years, this system could form its own solar system or be eaten up by the massive gas within it.
WASP-12b is a planet orbiting very far from its parent star. WASP-12b was discovered via the Hubble telescope. However, this gas planet is slowly being eaten by its parent star. WASP-12's atmosphere is reduced by at least 189 thousand trillion tons per year. As a result, the age of the planet is only 10 million years.
Next is the darkest planet ever. TrES-2b is a planet that has no light on it. The size of this planet itself is like the planet Jupiter. Why is the planet so dark? Investigate, TrES-2b is formed from the evaporation of sodium and potassium compounds, as well as titanium oxide gas which absorbs all kinds of light. This planet can only reflect 1% of all light. So dark, the color of this planet is blacker than charcoal.
|Super Saturn J1407-b|
Saturn is the most unique planet in our galaxy because it is the only planet surrounded by such a beautiful ring. Well out there, there are planets that are very similar to Saturn, even have rings too.
Super Saturn J1407-b is a planet that has a mass 20 times heavier than Saturn and its ring size is 200 times larger! The diameter of the ring reaches 180 million kilometers. That distance is further than the distance from the sun to the earth.
On Earth, humans celebrate a birthday once a year. But just like that we must feel very old! How about you celebrate your birthday every 10 hours! That's what would happen if you lived on SWEEPS-10, the fastest planet ever.
The location of this planet is very close to its parent star, with a very large gravitational force. Because it is only 1.2 million km from the parent star, the planet's revolution cycle is only 10 hours! That is, 1 year on Earth is equal to 10 hours on the planet SWEEPS-10.
Well, that's my discussion of the most extreme planet in the universe. Of course, it doesn't stop here. In the coming years there will be more discoveries made by scientists and of course there will be other extreme and certainly more unique planets.
Looks like our discussion has ended here, okay, thank you for reading my writing about outer space, hopefully the information from my writing can add to your knowledge about outer space which is very broad.
