About a month ago was detected Oumuamua, a highly elongated asteroid coming from outside our Solar System.
This is the first time such an “interstellar traveller” is detected : its orbital eccentricity is the highest ever measured in our Solar System, meaning this asteroid travels through our galaxy, the Milky Way.
It was named “ ’Oumuamua ”, the Hawaiian for “scout” – a messenger from the past.
The asteroid’s alien nature is reflected in its bizarre properties : Oumuamua is about 180 meters long but only 30 metres wide, and travels at a up to 88 km/s – a much higher speed than our Solar System’s asteroids’.
The paper was published yesterday in Nature. Make sure to visit its Wikipedia page or the NASA article about it!
