What is behind the sun? Are there any other planets behind the sun?
1 Answer
No, but there are some interesting related facts...
Explanation:
We have probably discovered all of the objects in our solar system that we would call planets.
When you say 'behind the sun', that would require some kind of orbit synchronised with our own, since the Earth is not stationary.
About the closest possibility to such an occurance would be a 'counter Earth' at a location known as L3 - the Langrangian point behind the sun (from our perspective) where the gravitational and 'centrifugal' forces would be balanced.
There are two drawbacks to such a theory:
-
L3 is unstable.
-
Now we have been able to make observations
from space, we can see that there is no such planet at L3.
Interestingly, while two of the other Langrangian points L1 and L2 are also unstable, there are two which are stable, namely L4 and L5. The L4 and L5 points associated with the Earth-Sun orbit contain interplanetary dust and at least one asteroid, that goes around the sun with us.
