Astronomers have found the possible sibling of a planet sharing the same orbit of a distant star.The researchers detected a cloud of debris that might be sharing the planet's orbit, which could be the building blocks of a new planet or the remnants of one already formed.The discovery would be the strongest evidence yet that two exoplanets - planets outside our solar system - can share one orbit, if it is confirmed.Restriction: Do not obscure courtesy straps.
