Can the number of planets live up to billions?

According to scientists, the stars in the Milky Way are close to one to three possible planets.

>> 60 billion planets can support life

Billions of planets have life on the Milky Way

Astronomers have come to this conclusion after calculating the number of planets located at a distance away from the star just enough to have warm temperatures and water oceans, from which there will be life.

Researcher Steffen Kjaer Jacobsen of the University of Copenhagen (Denmark) said: 'According to the data and information we have, most of the planets in the habitable area will be planets. snakes can have liquid water and survive. '

Every star in the Milky Way has 1 to 3 planets that may exist.

This finding is based on a data from NASA's space satellite Kepler (USA) , which previously confirmed the existence of about 1,000 planets orbiting stars in the Milky Way and has identified about 3,000 planets may have life.

Many stars in the Milky Way are in a system of 2 to 6 planets, but scientists believe there are still many planets not yet discovered by Kepler, which are only suitable for detecting large planets. has orbit close to the star.

In order to determine the location of these 'undiscovered' planets, scientists have adopted a mathematical concept that existed 250 years ago called Titius-Bode's law , which was used to discovering Uranus's existence before officially discovering through telepathy.

This law states that there is a certain ratio between the solar orbiting cycles of planets in the same system . Therefore, if we know the time it takes for a planet to orbit a star, we can calculate the time of the remaining planets and thereby estimate their position in the system. In addition, it can determine the actual number of planets of a solar system.

'We decided to use this method to calculate the position of the planets in 151 systems, where Kepler satellites only detected 3 to 6 planets,' Jacobson said.

'Titius-Bode's law proved accurate for 124 planetary systems. In this way we have tried to judge if there are any other planets in the systems. But we only calculate based on the planets you can see through Kepler '.

Accordingly, scientists predict a total of 228 planets in 151 systems and conclude that each system has an average of 1 to 3 planets in the habitable zone. This means that in the Milky Way there are billions of stars in a system of planets where water and life exist.

Scientists have come up with a list of 77 'undiscovered' planets, most likely to be discovered when they pass through the star in their system.
