Unique and Interesting Exoplanets

There are many exoplanets in our universe, all with varying characteristics. Here are just a few of them that have been discovered.

#1: The Ocean Planet – GJ1214b

This planet is likely to be an ocean planet, meaning it is entirely covered with one large ocean (no land). It is located about 40 light-years away from Earth.

#2: The Fast Planet – PSRJ1719-14b

Exoplanet PSRJ1719-14b quickly orbits its star; it takes about 2.2 hours for the planet to complete a full orbit around its sun. However, this is not the planet’s only unique characteristic. In addition to its fast orbit, this exoplanet also has a chance of being made of diamonds, although this has not been proved. Diamond planets form when the pressure and temperature are high enough to turn the carbon on the planet into diamonds. It is about 3,914 light-years away from Earth. 

#3: The Dying Planet – WASP-12b

Despite being around the size of Jupiter, this exoplanet is constantly nearing its star. Eventually, the gravity of its star will pull this planet into the star. Currently, this planet is 870.8 light-years away from Earth.

#4: A Large Planet – TrES-4

This planet is over 70% of the size of the largest planet in our solar system, Jupiter. What makes this planet unique, however, is that it has only %75 of the mass of Jupiter, giving it a much lower density. It is 1562.3 light-years away from Earth.

#5: An Old Planet – Methuselah

Estimations predict Methuselah is about 13 billion years old. Scientists believe that at that point in time (13 billion years ago), the materials to form planets were not actually able to form planets. This exoplanet is about 12,400 light-years away from Earth.

These are just a few of the many amazing exoplanets in our universe, with many more still waiting to be discovered.

Exoplanets and the Transit Method

Have you ever wondered about exoplanets? Exoplanets are the planets outside of our solar system.

There are multiple methods used by astronomers to discover exoplanets. One of them is called the Transit Method. As planets orbit their stars in a mostly circular way, exoplanets will always pass in front of their own star (at least, to our own perspective). During a planet’s transit around its star, its effects will be somewhat similar to an eclipse. The amount of light given off by the star that is visible from Earth will decrease until the planet completes its transit. Using the data like the drop in the star’s brightness and how long the transit was, astronomers are able to make various calculations. Not only are they informed of the exoplanet’s existence, but they also discover the exoplanet’s distance to its star or how long its orbit takes. More than 3000 exoplanets have been discovered using the Transit Method to this date. 

Still, though, there will always be mistakes in using this method as well as any other methods. There may be unseen details or simply missed periods of light differences by astronomers’ telescopes and graphs. There may always be unobservable celestial objects in our universe that may remain undiscovered. All we can do is try to discover as much of it as we possibly can.

I think it is very important that we discover more about this infinitely large universe we live in before other galactic clusters move out of our observable universe. This will eventually happen, as the universe is constantly expanding at an accelerating rate, moving an increasing amount of celestial objects out of our observable universe every moment.
