Astronomers have found a mile stone for the discovery of another earth, they have discovered two Planets, orbiting a star. And these two planets are the size of the Earth!
These planets have been named Kepler 20e and Kepler 20f. In the picture, you can see that our maternal planet is just like the size of the earth. The diameter of 20e is 11,100 km and the diameter of 20f is 13,200 km. The diameter of the Earth for comparison is 12,760 km. These two planets are the smallest planets discovered outside of the Solar System. The smallest planet previously found was Kepler 10b, which was 40% larger than Earth.
But make it clear that both of these planets are of the Earth’s shape but not like the Earth. Their maternal star Kepler 20 is like our sun, but it is a little bit cold and slightly cold. This star is 950 light-years away from us. But these two planets are nearer to Earth than the planet Earth and the Sun in orbit of Kepler 20. Their class is 76 lakh km and 166 lakh km with their maternal star. This class is so close to its maternal star that the surface temperature of these planets reaches up to 760 degree Celsius and 430 Degrees Celsius respectively. Of these, cooler planet Kepler 20f is also sufficient to melt tin or zinc.
It will be a hurry to pack suitcases for the journey of these planets, although it will take millions of years to go from rocket to these. We just do not know the mass of these planets. But due to the size of these planets, their mass will be similar to Earth.
This proves that Kepler Space Observatory is capable of discovering planets like Earth in space. This campaign is progressive in the right direction.
It also shows that our solar system is not alone in itself. We know many stars who have their own planet but all the planets found so far were great and their search was easy. But Kepler 20e and Kepler 20f are like Earth and this is a great discovery.
There are also three additional planets in the Kepler-20 division, which is larger than Earth, their name is Kepler 20b, c and d, their diameter is 24,000,40,000 and 35,000 km respectively, which is less than Neptune and Uranus, despite this is the Giant Planet . We know their mass, their mass is 220.127.116.11 and 20 times more than the Earth respectively. You can call them great grandfather.
All of these planets are fairly close to their stars. The most exotic planet is Kepler 20f, but this system is comparatively comparable to the orbit of Mercury. This system is different from our solar system. In our Solar System, the low mass of planets are inside, and the more massive planets are out, but in Kepler 20 it is alternate, the larger the planet – the small planets – the larger the planet – the smaller planet …
How do we know all this?
Kepler Observatory is in space, he inspects a small part at a time. Its view panel has 100,000 stars, which also has Kepler 20. When a planet orbiting a star goes in front of its maternal star, there is a slight decrease in the light of that star, it is called infection (eclipse). The larger the planet, the more light will stop. This reduction of light catches the observatories of Kepler and its size becomes known by the amount of light decreased, in this way we have known the size of these planets.
Kepler 20 star system
When this planet orbits its stars, then they diverge their maternal stars from their gravity. This deviation can also be measured with the light of that star, this deviation is seen with the Dapler effect coming in its light. This Dappler deviation shows how much the planet’s gravity is impacting on that star, and this gravity depends on the planet’s mass. In the Kepler 20 system, we have been successful in measuring the gravitational effect put by its large planets, from which we only know the mass of its large planets. But Kepler 20e and 20f are so small that we are unable to measure their gravitational effects.
Make another fact clear that we know the existence of these planets, we do not have any picture of these planets. The picture presented is based on imagery. The existence of these planets is indirect proof that means they are influenced by the impact on their maternal star. These methods are universal, so we can say that the existence of these planets is uncertain.
The discovery of these planets is a step in the right direction. Our direction is that in the gold-plate region of a star where water can live in its liquid state, the earth-like rocky planet is discovered! Hope to find such a planet in the near future. And this day is not far away.
