The Oort Cloud

I thought that this rappers name looked familiar.

The Oort cloud was named after Jan Oort, a dutch scientist who hypothesized about it.

Here is what Wikipedia has to say about it:

The Oort cloud (pronounced /ˈɔrt/ ort, alternatively the Öpik-Oort Cloud IPA: [ˈøpik]) is a hypothetical spherical cloud of comets which may lie roughly 50 000 AU, or nearly a light-year, from the Sun.[1] The distance places the cloud at nearly a quarter of the distance to Proxima Centauri, the nearest star to the Sun. The Kuiper belt and scattered disc, the other two known reservoirs of trans-Neptunian objects, are less than one thousandth the Oort cloud's distance. The outer extent of the Oort cloud defines the gravitational boundary of our Solar System [2].
