A rocky, hot, and Earth-sized planet, discovered orbiting near our sun some time ago. From this discovery, our scientists and astronomers predict that alien life outside our solar system can be traced from that place.
This planet is called GJ1132b. Today, scientists are closely observing it, and it is confirmed that the planet has a thick, water-rich atmosphere.
Let us discuss a bit about the planet, here are 4 facts,
1. The planet was discovered in 2015 and is in another solar system
Planet that staying digadang have similarities with this Earth, was first discovered by scientists in 2015 ago. At that time, the planet is still predicted to consist only of stone and iron. And predicted to have a very hot temperature like an oven.
The planet is slightly larger than Earth, which has a size 1.2 times the size of the planet we live in.
GJ1132b orbits to its own 'sun', a dwarf star named Gliese 1132. Its distance to the main star is quite close to the Earth's distance to the Sun. Scientists predict that the planet gets radiation 19 times higher than we do on Earth.
2. The planet has a thick atmosphere
Recent recent studies, which show that the planet shows a thick atmosphere that allows for the existence of life, as well as the amount of water that is quite abundant like on Earth.
However, the temperature of the Planet is too hot to be inhabited by humans. According to scientists, the surface temperature of GJ1132b lies between 136 degrees Celsius to 306 degrees Celsius.
Although hot, the planet is very fitting for the substance of the atmosphere that protects it. In addition, the size of the planet also makes there a lot of interior composition in it. Starting from the rocks to the water very much.
3. Atmospheres The planet is found using a sophisticated way
Scientists led by Dr. John Southworth of Keele University, studied the atmospheres of the Planet using the method of planetary transit variation in our Solar System. This is done by looking at the amount of sunlight that should shine on the planetary system.
Of course if there is a planet that crosses our sun, there will be little sunlight that is dispelled by the size of the planet. In the case of GJ1132b, 0.3 percent of the light decreases every 1.6 days.
This is seen through the European Southern Observatory's MPG / ESO telescope in Chile, which is 2.2 meters in size. From this tool is seen GJ1132b planet passed 9 times.
4. The planet is very close
This time scientists are studying more about the planet. And the most stunning news of this research is that the distance is close enough to the planets of similar findings.
Compared to other planets or stars found in the universe, the planet GJ1132b is only 39 light-years away. Illustration of distance can be seen in the picture above.
Scientists finally describe this planet as one of the most important planets ever found outside our solar system. [idc]
