Is there a 6th Earth, is there a second Earth in the universe?

So far, it hasn't been found.

To date, astronomers have discovered about 300 planets orbiting stars outside our solar system, but all of these extrasolar planets, like Jupiter, are huge planets shrouded in gas, which are not at all suitable for life on Earth. However, scientists have always believed that there must be countless "solar systems" in the vast universe, and there must be planets similar to the earth waiting to be discovered by human beings.

Yes, I found one a few years ago, and there is an introduction in popular science magazines, so if you are interested, you can subscribe to ,.. or somethingAs for that one, it is speculated that the plants on it are red and blue, which is related to the wavelength of the color light they absorb, and the reason why it is called"Second Earth"Its mass, gravity, revolution, rotation, and atmospheric composition are similar to those of the Earth (compared to other planets), and its cosmic environment is also very similar ,..But it will take more than 50 years to reach it at the speed of light, so it will be a matter for the next generation to go there.

There is only one Earth, and the other planets adapted to human habitation

1.Earth is one of the eight planets in the solar system, the third in order of near and far from the sun, and it is also the terrestrial planet with the largest diameter, mass and density in the solar system, 100 million kilometers away from the sun. The Earth rotates from west to east while revolving around the Sun.

Now 4.046 billion years old, it has a natural satellite, the Moon, and the two form a celestial system, the Earth-Moon System. It originated from the primordial solar nebula 4.6 billion years ago.

2.The Earth's equatorial radius is kilometers, the polar radius is kilometers, the average radius is about 6371 kilometers, and the equatorial circumference is about 40076 kilometers. The surface area of the earth is 100 million square kilometers, of which 71% is oceans and 29% is land.

At the moment, there is only one. But other possibilities are not ruled out.

b Earth is a planet in the Sail Solar System that scientists have speculated.

It is said that the bearth is exactly the same as our earth, as far from the sun, and the same size, and the same water, and the same life, except that the people of the earth can never see it, because it is on the opposite side of the earth, and the sun is separated from it.

There is a theory that on the other side of the sun there is a bearth, rich in matter and also suitable for the survival of man. And does this bearth really exist?

According to the theory of astronomy, the existence of a celestial body will inevitably have a gravitational connection with the surrounding celestial bodies, just like the sun and the earth, there is a huge gravitational connection between them, so the result of the sun and the earth attracting each other, is it getting closer and closer? Of course not, this is also related to the centrifugal force generated by the rotation of the earth around the sun, as if we use a rope to tie an object and rotate rapidly, at this time, because the centrifugal force is equal to the pulling force of the rope, the object will always adhere to the same orbit around the center, and the same b earth must always remain in the same orbit as the earth, and must have the same mass as the earth in order to meet the condition that gravity and centrifugal force are equal, but according to Bode's law, in the orbit of the earth around the sun, only one planet is allowed to exist. Therefore the bearth is a hail of the year that does not exist.

At present, human beings have discovered more than 100 exoplanets, of course, there are planets similar to the Earth's cosmic environment, but whether there is life or not can not be detected. In the vast universe, there must be a second earth.

That's just a guess and it's not confirmed. What I do know is that, according to the law of electrons and anti-electrons, people have put forward the idea of two more earths, one is the state fighting the earth, and the other is anti-earth.
