Discover the mystery of 'Second Earth'

Kepler-452b, the most Earth-like planet discovered so far, may be warmer, wider, and have surface water.

New mysteries to discover "Second Earth"

The US Aeronautics and Aeronautics Agency today announced the discovery of Kepler-452b, which is regarded as the "Second Earth", with many characteristics suitable for the development of life as the planet.

1. Time on Kepler-452b is similar to Earth

One year on the "Second Earth" - the time for Kepler-452b to turn around the mother star is 385 days, just over 20 days compared to a year on Earth.

This is a noticeable difference from other planets near Earth like Venus . One year of Venus is Earth's 88 days, and one year on Neptune - the planet further in the Solar System, is 185 years of Earth.

2. It has spent billions of years flying in suitable areas around its mother's stars

Kepler 452 - Kepler-452b's mother star, about 1.5 billion years older than our Sun. If a planet is too close to its mother, it will be too hot to form life. If it is too far, it will be too cold, it cannot form life.

Kepler-452b keeps an ideal distance from its mother star in billions of years. According to Jon Jenkins, the analysis data of the Kepler space probe shows that this means that it is most likely suitable for life that arises on the surface, or at least, that every life exists.

3. There may be active volcanoes and surface water

It is possible that Kepler-452b has the right temperature for water to exist in liquid form on the surface. This is necessary to support life.

According to John Coughlin, researcher at the SETI Institute, California, USA, the Kepler project team has collaborated with geologists to find out the structure of the planet. Based on its size and age, this seems to be a rocky planet , meaning that volcanoes are active below the surface.

4. Humans are able to live in a strong gravitational place in Kepler-452b

The new planet is slightly larger than the Earth, estimated to have a force twice as strong as the planet. However, according to Kepler project scientists, this does not mean that it is not suitable for living on it.

Jenkins said people can " adapt " to that gravity, even the body will "become more muscular and muscular over generations."

"People are willing to adapt to heavy weight - human beings are born to do this. The human body is capable of excellent repair itself. So over time, people can adapt."

5. Flora grows

Kepler-452's mother star is bigger than our Sun. The light and heat that it receives from its mother not only makes it warmer than the Earth, but also means that the flora can grow there.

Plants photosynthesize, creating an atmosphere for people to breathe. Accordingly, if building vegetation is large enough, producing enough air for humans and animals living in Kepler 452b.

" The face light from why the Kepler master is almost the same as our Sun. Therefore, plants can have the same photosynthesis. It must be very similar to Earth, " Jenkins said.

6. Tanned skin

"Kepler 452b recognizes the same spectrum and light intensity as we get on Earth. Therefore, if this planet is a rocky planet and has an atmosphere, plants can grow. We even You can even go on vacation there, drying your tan, " said Daniel Brown, astronomer, Trent University, Nottingham.

Scientists are conducting a lot of research on the planet, to find out what can be developed on Kepler 452b.

7. Travel to "Second Earth"

Kepler-452b is warm, can have water and life, however, it is 1,400 light-years away from us . A light-year is the distance a beam can move for a year. Light moves about 670 million miles (1,078 million kilometers) an hour. Light from the Sun takes up to 8 minutes to reach Earth.

If a spacecraft carrying people to Kepler 452b, it would take 25.8 million years to get there. This is an unbelievable time for humans, unless we find a way to improve the speed of the spacecraft in the future.
