Interstellar object confirmed to be from another solar system

Astronomers have named interstellar asteroid 'Oumuamua and found it to be rich in organic molecules

Astronomers are now certain that the mysterious object detected hurtling past our sun last month is indeed from another solar system. They have named it 1I/2017 U1('Oumuamua) and believe it could be one of 10,000 others lurking undetected in our cosmic neighbourhood.

The certainty of its extraterrestrial origin comes from an analysis that shows its orbit is almost impossible to achieve from within our solar system.
