Now scientists are preparing to gather more information about the possibilities of life. Scientists say that most of these planets revolve around their stars just like the Earth. The most special of these planets is, KOI-7923.01. The size of this planet is like 97% of the Earth.
Planets are divided into 2 categories:

Scientists have divided these planets into 2 categories. Planets made of gases like the first planet Earth's shapes and rocks and the other Neptune or Varuna According to the scientists, in the universe, there is possibility of building up to 75% of rocky planets from Earth.
Why is KOI-7923.01 Important:

Of the 20 new planets, the KOI-7923.01 planet has been considered a very special to the scientists. The reason for this is that it is similar in size to 97% of the Earth. Not only this, it completes the orbiting of its star in 395 days.
But the special thing is that its star is very cold and it is located very far from its star, due to this, the planet is also very cold. It is believed that there can be a tundra state like here on Earth. Although it is quite cold but still hot enough for life.
