Beschreibung:

1I/ʻOumuamua as shown here imaged with the 4.2 meter William Herschel Telescope on the Canary Islands is seen as a point of light in the centre of the image. Background stars appear linear because the telescope was centred on tracking the object through 5 minutes.^[1]1I/ʻOumuamua (Weryk 2017 ^[2]), is the second known discovery of matter of interstellar origin within the Solar System ^[3] the first known interstellar planetesimal ^[4] and the first known interstellar object to enter the Solar System at a speed that resulted in a trajectory not orbital (ie. hyperbolic), ^[5] this being an interstellar speed of ^[6] 26.33 +/- 0.01 km/s ^[7] approximately Δ 26 kilometers per second. ^[8]
