Strangest Celestial Bodies in the Universe - 1


November 10th, 2019

By: Haris Ahmad[1]

There are many strange objects in the universe. Be it planets or galaxies or even objects that we don’t understand about. In this blog, I will uncover some of the strangest objects in the universe that most people don’t know about. Before starting, I’ll explain some terms to you for basic understanding. Astronomically speaking, only the planets in the Solar System are classified as planets; but the planets that are beyond/outside of the Solar system are called ‘Exo-planets’.

Moreover, any object in the universe, be it a star, planet, moon, or asteroid can be called a celestial body. Thus, any natural body in space is called a celestial body.


The first celestial body I will talk about is the Exo-planet 'J1407-b', which is a hot gas giant, located 400 light-years away from us. It has a diameter of 129341.77 km. The strange aspect of this planet is its huge rings.

This planet has rings, those are approximately 200 times bigger than Saturn’s rings. Scientists still cannot understand how this planet got rings that big. Saturn is surely jealous of this planet's ring system. However, they won't stay for long and will disappear in a few hundred thousand years. 

Furthermore, another Exo-planet named as HD 106906-b that exists in the Crux  constellation that is approximately 300 light-years from Earth, is known as the loneliest planet in a planetary system in the universe because of the fact that that it is 650 AU (Astronomical units) away from its parent star named as HIP 59960. This is a huge number because 1 AU is equal to the distance from Sun to Earth. Scientists still can't understand how this planet formed being such distant from its parent star and how does it orbit its parent star from such a distance.

The next celestial body I am going to uncover is also an Exo-planet. The name of this planet is TrES-2b.

It is a scorched gas giant and has a diameter of 178301.05 km. The strange thing about this planet is that it reflects less than 1% of the light that hits its atmosphere making it the darkest planet in the universe. Believe it or not, if you were to see this planet in front of you in real life, you would see a huge scorching ball of gas darker than coal. In the words of Dr. David Kipping (one of a scientist who discovered this planet) “Some have proposed that this darkness may be caused by the huge abundance of gaseous sodium and titanium oxide. But more likely there is something exotic there that we have not thought of it before.”

Moreover, another strange planet I'll explain is an Exo-planet that is located 40 light-years away from us. Some even call it a girl’s best friend because it is a huge diamond (Just Joking). The name of this planet is 55 Cancri-E.

It orbits its star at a distance of 22.27 million km, which is very close. Scientists say that when this planet formed, it comprised mostly of Carbon, but due to the intense pressure and heat from its parent star, the carbon got compressed into a diamond. If you were to possess all the diamond this planet has, you would be able to earn 26 nonillion dollars (That is 30 zeros). However, sadly the market for diamonds will crash and it won't be worth anything. 


Furthermore, the next strange planet is Wasp-12b. It is a scorched gas giant. It has a diameter of 248220.22 km.

It is very close to its parent star, which is why its star is literally eating it alive. The star is slowly sucking down the mass of the planet and has also distorted it into the shape of an unnatural egg. For a comparison with Mercury, this planet orbits its star at almost 250, 000 (Rounded up for example purposes) whilst Mercury orbits the sun at 57 million km. Therefore, now you may have got an idea of how close this planet is and how hot it may be. 

The last planet I am going to talk about is Wasp-17b, which is the largest planet in the known universe. It is a strangely large planet and is very similar to Jupiter, but the difference is that it is 1.9 times larger than Jupiter making it unusually large.

It doesn't end here though, the orbit of this planet also makes it stranger. It has a retrograde orbit, which means that it orbits its parent star in the opposite direction. Thus, the secret behind this planet remains a rare stellar mystery. The parent star of this planet may also wobble a bit due to its ginormous size and mass.
