If you've read science fiction, maybe you'll read some stories about "on the other side of the solar system, there's another planet the same size as Earth, but obscured by the sun orbiting." Is this true?
No. No way. This is absolutely impossible.
This would be a flattering theme in science fiction. On the other side facing the sun, in the same orbit, there is another mysterious world, but it is located directly opposite the sun and is always obscured by the sun. We hardly knew it existed, but now they were assembling their fleet to attack us. We must invade another earth before attacking us, stealing our water, eating all our cheese, or kidnapping our beloved Nigella Lawson and Alton Brown to become the culinary kings of their planet.
So, will this happen? Will there be a planet with a stable orbit behind the Sun? The answer, as you might have guessed, is absolute — impossible.
This thinking is wrong. If some powerful and powerful spaghetti is magically crafted into another planet, thrown into an orbit, it will be largely blocked by the sun and invisible to us. But the Sun and Earth are not the only ones in our solar system. As the Earth orbits the Sun, it also allows us to orbit slower or faster due to the weak influence of the surrounding planets.
So, when we're pulled closer by Jupiter in orbit, the other planet will be in a position directly opposite the Sun. In this way, we will speed up a little so that we can go around the sun and be able to see it. Many years later, as these different movements accelerate, we will see that planet more and more in the sky, and we will be in orbit about to catch up with it.
Eventually, our orbits will intersect with each other, and after that there will be a collision. If we're lucky, maybe two planets will pass each other and then produce new, safer, and more stable orbits around the sun. But if we're not lucky enough, it's clear that in this case the two planets will collide, forming a new giant Earth that wipes out everything on both planets.
Could it be that there were originally two "half" Earths, and then they collided and got the Earth we have now. Or four Earths with 1/4 of their own population, and then they collide and a large Earth appears. Or there are 64 1/64 parts of the Earth, and together they will form a VoltreEarth!
Now, I'll make things seem a little more serious and add some science to your imagination. There are places in the universe where objects can share the same stable orbit. These sites are called Lagrange points, which are points in which a stable position is created for the third object under the gravitational force of two objects. The best locations are the L4 and L5 in Lagrange Point. L4 is located about 60° in front of a planet in orbit, and L5 is located about 60° behind that planet.
Illustration of five Lagrange points
In relation to the helio-Terrestrial system, the DSCOVR (Deep Space Climate Observatory) moves at L1 points in the orbital graph. The picture is not rendered at the actual scale.
A small enough planet-related object can stay in a stable position for about a billion years. Jupiter has many Trojan asteroids at L4 and L5 points in his orbit that have been at a steady distance from the planet itself. And that means, if your gas giant planet is massive enough? You will not be outside the direction of the stable orbit of the planet, there are many terrestrial planets.
It's really an interesting idea. Unfortunately, under the combined action of Earth's gravity, the existence of this hidden planet has become completely impossible. What's more, when someone tells you that there is a hidden planet behind Earth, remember the following words: No. No way. This is absolutely impossible.
