There are 7 Worlds that you never heard of what are they
On May 2 1016 astronomers from ESO Lacia Observatory detected that a dim and cool star faded slightly at regular intervals indicating that several objects were passing between the star and the earth. The observation was made using the Trappist Telescope. As early as February 2, 1017, Nasa held a press conference and announced the discovery of a seven planet exoplanet system located in the habitable zone and can potentially have water on its surface. In this video, you'll get Can know how much water there is on these planets. Whether or not they are potentially habitable. What makes them similar to earth? And most importantly, why do they still exist without bumping into each other? Even though they should have collided according to scientific calculations. Let's figure it out right now Now. The trap is one star with first discovered in 1999 by john geese and his team. Its name comes from a small telescope called transiting planets and plantations that was used to detect it Some 39.46 light-years away from earth. It isn't ultra-cool, a red dwarf of spectral glass NBA is only slightly bigger than Jupiter. And its mass is about 8% of the sun's mass. Which makes it even cooler and dimmer. The store's radiant Is 12.1% of the sun's radius is estimated to be between 5.4 and 9.8000000000 years. Taking the storms age into account is very important for understanding if the surrounding planets can be potentially habitable Trapped one is about twice as old as the solar system which was formed about 4.5000000000 years ago. On May 2 1016 astronomers from ESO Lacia Observatory detected a dim and cool storm indicating that several objects were passed Between the store and the earth. The observation was made using the Trappist telescope. A detailed analysis revealed that there are three planets resembling Venus and Earth orbiting the star 2016 scientists used Nasa's Hubble telescope to discover that these planets mostly Likely don't have an atmosphere of prevailing hydrogen. Hence, these planets can be rocky and possibly have water on their surface. As early as February 2, 1017, scientists can announce the discovery of four more planets at a press conference by Nasa. Thus, it became clear There are seven earth-sized planets in the system telescope, transiting planets, and planet testimonial small telescope and chilly and other ground telescopes were used to detect and characterize planets. Astronomers claim that three of these planets are in the theoretically habitable zone Hey. Proximity to their store. The largest planets G and B are about 10% larger than earth. The small Was planets D and H are about 25% smaller than our planet. Researchers determined that the farthest planet from the store orbits at the store every 19 days telescope. This is still much shorter than the orbit of mercury Which goes around the sun every 88 days. But because the trap is one is so faint. It outputs only .05% of the amount of energy of the sun and may be covered in ice. The amount of energy per unit area that one Asteroid belt between Mars and Jupiter receives from our son is the closest one to the star with an orbital period of a day and a half its orbital radius is almost 100 times smaller than that of the earth. The Trappist one planets are so close together that if you could stand on the surface of the one you might see some of the neighboring planets hovering above. Scale wines the structure of this planetary system resembles the satellite system of Jupiter. More than the structure of the Solar system. Start to trap us one is a small and relatively cool red dwarf star belonging to spectral class M. They are the most common stellar objects in the universe. And makeup 70 to 90% of all observed stars System. Roughly the size of the earth. Three of them are in the habitable zone. Meaning they're a distance from their parent's store allows them to have liquid water on their surface. And this can most surely indicate that red dwarfs have many Earth-like planets. After all To be the primary candidates for potentially hosting live outside the solar system. After discovering the therapist one system researcher tried to study its stability using computer simulations with different initial conditions. However, the simulated planet's almost always collided about half a 1 million years after their origin. Literally destroying the entire system. When assessing the planetary system's stability, the researchers concluded that there is a stabilizing factor. The researchers found out that the time it took for each planet to complete a circle around its store was crucial. The thing is their orbital periods make up a surprisingly accurate progression. For every two orbital cycles, the farthest planet from the store is complete. The closest one to it orbits the star three times. The next one four times And 24 times respectively. Thus, achieving a two to three resonance. Where the planet's orbital cycles reach a two to three ratio. It works like clockwork. There is no long-run and chain-like it in other planetary systems Works. In other words, each planet orbits the star in alignment with its neighbors in the system. Therefore, this unique property allows the entire system to exist for a long period of time. Allowing scientists To observe it. The trap is one system containing a total of seven earth-sized planets. Three of them therapists 1D E and F are in a potentially habitable zone suited for having liquid water on the surface planet's one B and C or two Close to their parent's star and one is too far away. The measured density combined with planetary compositional models suggests that the surface of the trap is one planet that is far from being a barren rocky desert apparently they contain a significant amount of volatiles and water The volume of the ladder reaching up to 5% in some of the planet's masses. This is a pretty high percentage for comparison purposes, water constitutes only 0.02% of earth smash is the only planet in the system that is slightly denser Than earth. This could mean that it may have a denture iron core. Lack of thick atmosphere. Oceans, or an icecap. This planet turned out to be much rockier than all the other planets of the system. In terms of size, density, and the amount of stellar flux. This planet is more similar to To earth than all the others. According to the habitable exoplanets catalog, therapist one E is one of the most potentially habitable exoplanets discovered so far. The trap is one E is confirmed to have a compact hydrogen-free atmosphere. Like those of our solar systems rocky plants Further raise the chances of habitability. Hydrogen is a powerful greenhouse gas. So if there was enough to be easily detected it would mean that the surface of the trap is one E would be inhospitable. Since such an atmosphere is not present it raises the chances for the plants To have a more earth-like atmosphere instead. Trappist one F is the fifth farthest planet from its parent's star in the seven planet system it hasn't diameter close to that of the earth but is much lighter weighing only 0.36 earth masses Most likely indicates a significant amount of water or other light substances in its composition celsius is the third farthest planet from the star. With an average surface temperature of +15° And slightly smaller dimensions compared to earth. Its radius was as much shorter than the earth's radius. And its massif only 0.33 earth matters the closest planets of the system to the parents store most likely have a rocky cool And are surrounded by a much denser atmosphere than earth. According to density measurements, planet B can either have a small core or more likely contain a significant amount of water or other volatile than its composition has the smallest radius and mask on Its cousin. The surface temperature is estimated to be at a life-threatening -104°C one eight orbits star every 19 days. This is still much shorter than the orbit of mercury. But because Travis is so faint. It only outputs.05 The amount of energy of the sun planet age receives a lot less heat than mercury and may be covered in ice.
