Scientists spotted two of most distant objects found in our solar system
One of them may be a super Earth, according to the Swedish-led studies
Their speed and brightness suggest the objects are unlikely to be stars
The studies have already drawn scepticism from other astronomers who say they are likely to be something known as super-cool brown dwarfs
The paper has yet to be peer reviewed, but it presents some interesting conjecture. Our solar system may be far more interesting than thought.
