All measurements are the circumference of the object based on the accepted equatorial radius.
The Observable Universe measurement is based on the cosmic light horizon being 46 billion light years in every direction. ((pi * 2) * 46 10^6 ly) * (5.87849981 × 10^12)
Due to the rounding of certain numbers during the calculation of the circumferences, there may be some errors in the final figure.

There used to be a theory about this, if I understand what you're saying. That there is another planet in earths orbit, always on the opposite side of the sun, so that we don't see it. But space probes and other tests debunked the theory.
but nothing has actually gone behind the sun and looked so there might be chances i see a lot of videos... and pretty much i have underestand that there can be hundreds and hundreds of planets just in the milky way.. i have no idea but i hate science but i'm very curious when it comes to space and this thing..
In order for another planet to have the same geosynchronous orbit around the sun as the earth, but be on the other side of the sun, it would have to be exactly the same size and exactly the same mass as earth. Otherwise it's orbit would be faster or slower than ours, and the two would have collided eons ago. What you describe is not possible under the physical laws of this universe.
