The Loneliest Planet: How Is Life On Rogue Planets?
From what it is, to what it might be like to live there, join me as we explore The Loneliest Planet: HOw is LIfe on Rogue Planets? I know what you're thinking, "wait, what is a rogue planet?" Out there, somewhere in the universe, are planets that are both just like all the others in the universe, and yet are infinitely different. These are known as Rogue Planets. And they're called that for a very simple reason. It's because these planets, for whatever reason, were born to the universe...without being tied to a star. Confused? I'll explain. If you believe in the big bang version of the creation of the universe, then you believe that when the "boom" of matter" happened, it flung everything out into the universe at large, and is even still expanding to this day. Galaxies formed via gravitational forces via the stars and planets that were made. Yet, the force apparently "kicked out" many planets, and they're now roaming the universe at large. There's even speculation that a rogue planet is just outside our solar system. The idea of other planets being just outside our realm is rather enticing, but it's also scary. Because a new planet suddenly appearing could throw our solar system into chaos. And if it's going fast enough as it hurdles through space, it could even crash into another planet. Maybe even Earth. There are some scientists who believe that the Earth has already collided with a rogue planet. And it was this collision that created the moon that we see above us. Showing that even in great destruction, there can be wonderful creation. Now the question should be asking is, "well how do we know that these Rogue Planets exist?" A very sound question given our more "rooted" place in the universe as well as how we are able to look at the stars and galaxies around us. Basically, we noticed some oddities as we looked at the stars themselves. In 2011, a study was published via scientists from Osaka University. They looked at over 50 million stars and noticed over 170 anomalies that didn't make sense at first. Objects that were bending light in a way that most objects don't. As they looked deeper, they realized that the majority of these objects were bending lights from stars or other objects, making them stand out from the crowd if you will. But ten of these objects were revealed to be not be anywhere close to any stars. What's more, they were as large as planets, and sometimes even as large as certain types of stars! It was here that we truly found Rogue Planets, and realized that they were moving through space at great speeds despite not having a tether to a parent star. So how do they move then? Well, not unlike virtually every object in the Milky Way Galaxy, they are tethered loosely by the galaxy itself, which has a gravity field that keeps the stars and planets in line so that they "go with the flow" of the galaxy if you will while not shooting out into other galaxies or deep space. The problem with Rogue Planets though is that because they don't have a closer tether to orbit around (like the Earth does with the sun) it's only loosely guided by the pull of the galaxy itself, and thus hurdles through unknown reaches of space. In many ways, a Rogue Planet is the "loneliest planet" in the universe. Not because it may not have life on it (which we'll get to in a bit), but because unlike virtually every other planet in the known universe, it doesn't get the light of a sun to show off its beauty, or get the warmth of the star to help make it more than what it is. And because it's a Rogue Planet (based on our knowledge of planets and their relationships to their stars) scientists believe that the whole entity is cold, frozen, and dark. Now, we noted a little bit earlier that these Rogue Planets were "kicked out" of their systems and that they're going through space at a good clip, but how fast are they going exactly? Well, we honestly don't know, because it's really hard to find and track these planets, however, we can do some comparisons based on a certain other thing we know can go rogue...a star. That's right, stars have gone rogue in the past and we've been able to track them, and when they go throughout space without a tether, they can reach speeds of up to 1.5 million miles per hour. So does that mean a Rogue Planet can go that fast? Sure, it could, but more than likely, it goes a lot faster. Why is that? Do recall that stars and planets may have similar sizes at times, but that doesn't mean they have the same mass. A star always has more mass than a planet, and so since Rogue Planets are smaller than stars and have less mass, that means that it takes less time and effort to move through space. So, knowing this fact based on basic physics, scientists have calculated that Rogue Planets could barrel through space at a rate of 10-30 million miles per hour.
