As science progresses, as the power of space telescopes increases, new stars and planets appear.
A study has revealed that there are at least 6 billion Earth-like planets in our galaxy.
Earth-like planet refers to a planet that has a system similar to our solar system. There are a few other planets in this system that revolve around the Sun in this system. A planet like our Earth is about the same distance from the Sun as our Earth. The diameter of the planet should also be close to our earth. This planet has rocks and plains.
When these factors are available, there will be water and air. This can make the planet's temperature and weather conditions conducive to life. Life there does not have to be like life on earth. It can take any form, but in the presence of these factors the possibility of life there becomes stronger. This type of planet is called G-type planet in scientific terms.
Astronomers estimate from data from NASA's powerful telescope that the number of G-type planets in our galaxy, such as our Earth, could be as high as 6 billion.
"According to my calculations, the number of Earth-like planets in a G-type solar system is zero point eight percent," said Michelle Connie Moto, an astronomer at the University of British Columbia and author of the study. These are the planets that could be the focus of our future space exploration.
According to a conservative estimate, there are 400 billion stars in our galaxy, which have their own solar system and many planets revolve around them. Of these 400 billion stars, 7% are those that meet the G-type definition. This means that there are about 6 billion Earth-like planets in our galaxy alone.
The closest planet to Earth is Mars, which is 55 million kilometers away from the Earth. It takes 150 to 300 days for a rocket to reach this planet, depending on the rotation of Earth and Mars in their own orbits.
It could take hundreds or thousands of years to reach a planet like Earth from another solar system outside our solar system, because they are orbiting at infinite distances and humans can still reach speeds of more than a few thousand miles per hour. Has not been able to.
