Planets orbiting two suns, is not just an ordinary statement. It sounds like science fiction, but now scientists believe these strange worlds actually exists in our universe. In recent study scientists found many planets (around 27 planets) that are revolving around the two suns. This discovery creates a new image of planetary system in people’s mind. Planets orbiting two suns feel very unusual because most of the planets in our solar system have only one sun.

Now scientists already confirmed that binary star systems are common in our galaxy, Milky Way. Many stars exist in pairs in our galaxy. It means there could be very strange worlds in the cosmos. Some of these planets have completely different environment than earth. It feels very dramatically, that planets exist in the space where two suns rises in the sky instead of one. Let’s discuss more about these planets orbiting two suns.

Planets Orbiting Two Suns

It involves those planets that are revolving around the two stars instead of one, like our Earth orbits single sun. Scientists call these stars, binary star system. In this system planets revolve in the orbit called circumbinary orbit. In simple words, planet revolves around the two stars that are themselves orbiting each other. This planetary system is very different from our own.

Earlier, scientists thought, it is very difficult that any planet can form in such unstable conditions because gravity from two stars would disturb the formation of a planet. But the latest discovery proved the earlier thoughts are wrong. With the help of powerful telescopes, scientists have found many planets orbiting two suns. One of the most famous examples is Kepler-16, also known as “real-life tatooine”. These planets have very strange climate and seasons because the distance and light from the both stars changes. Sometime planets become hotter and sometimes become colder, it depends on the motion of the stars. How they revolve around each other. It shows these star systems are very different from our own solar system and still many mysteries are waiting to be solved in the universe.

NASA record the scariest sound in space

This discovery starts spreading very quickly because it feels like science fiction movies. Many people relate it with the fictional world like tatooine from Star Wars, where we see two suns in the sky at sunset. Recently scientists discovered 27 possible planets that are liked with binary star systems. For decades scientists only focus on the solar systems that are similar to ours. But now planets orbiting two suns are showing that space may far more complex than we imagine.

How Scientists Identified 27 Possible New Worlds?

Scientists use powerful telescopes, highly advance computers and special observation methods to observe these strange worlds. One of the most common methods used by scientists is transit method to detect far planets in deep space. In this method scientists observe brightness of the stars very carefully and they wait for the tiny drop in brightness. When a planet moves in front of the star, it blocks some light. By studying these repeating dips in the brightness of a star, scientists confirms that a planets moves around the star.

Finding the planets orbiting two suns in deep space is very difficult than a normal planets. Because both stars also move around each other, it creates a complex pattern of light and making the signal difficult to understand. With the help of advance computers and observation of many years, scientists able to separate the movement of stars from the movement of planet and successfully identify the planets orbiting two suns in the deep space. A very famous and powerful telescope called Kepler Space Telescope helps scientists to discover many worlds in the deep space. It found many circumbinary planets including kepler 16. Scientists also use radial velocity method to identify planets in space. In this method scientists study tiny wobbles in the star caused by the planet’s gravity. Sometimes scientists combine many techniques to identify planets. These special observation methods help scientists to detect planets located thousands of light years away from the earth that are not seen directly from the telescope.

Could Life Exist On These Worlds?

Scientists believe that, life could exist on some planets orbiting two suns. But it would depend on many important conditions. To survive on a planet like earth, it needs the right temperature, air, water and a stable environment for life survival. If a circumbinary planet located on habitable region where temperature is not too hot or too cold, then it may have chance for life to exist. Because of two stars, life could face some unusual challenges on those planets. The amount of light reaching on the planet changing continuously. It may cause strange seasons, climate shifts and unpredictable weather. Kepler telescope and James Webb Space Telescope discover many exoplanets. So scientists are interested in studying these planets because these telescopes help to analyze atmosphere, water and oxygen on the planets. Scientists have not found any sign of life on the planets orbiting two suns yet.

How Can A Planet Survive Around Two Stars?

A planet can survive around two stars, if it stays at a safe and stable distance from them. In most circumbinary stars systems, both stars orbits very close to each other. And the planet revolves around them at very far distance. Because of the greater distance combined gravity of both stars don’t act much, it almost act like a single powerful source. This allows the planet to revolve around them in a stable orbit instead of being pulled towards them. If the distance between the planets and the stars is close then the star’s gravity can make its orbit unstable. This result, the planet could be pulled and crash into one of the stars. But if the distance is far enough and orbit is stable then plane can continue moving around both stars for millions or billions of years. By using advance computer simulations and powerful Kepler Space Telescope, scientists discover that the planets orbiting two suns are actually stable.

Could There Be More Of These Worlds?

Many scientists believe the answer is yes.

In fact, now scientists think these worlds may be more common than we think. Because, there are many stars exists in pairs in our galaxy. So there is a great chance that planets around them are formed. As our telescopes improved and more data available, then scientists discover more unusual planetary systems across the galaxy. Some scientists believe that our current technology only reveals a small fraction of data of what exists in our galaxy. These planets are very difficult to detect because their movements are so complex and light from two stars make very hard to observe from telescope. Now scientists use new and more advance telescopes like James Webb Space Telescope that can help to study distant planetary systems with more details. Scientists believe future discoveries may reveal earth size planets revolving around two suns with habitable conditions where water may exist.

Conclusion

 In this article, we discuss about the planets orbiting two suns. Earlier, if anyone talks about a planet with two suns, it sounds us like a science fiction movie. But now scientists discover around 27 worlds having two stars and they also believe future discoveries could reveal many more. These circumbinary planets show that a planetary system can forms in a way that human never expected. They challenge our old ideas and theories about stability, habitability and how different types of worlds are common in our universe. Through this unique discovery, we get a massage that with our most advance technology, still we cannot fully understand the universe and the universe is full of mysteries waiting to be explored. Every new technology discovers something that completely change our way of thinking towards the universe.
