WHAT DOES OORT CLOUD MEAN IN ENGLISH?
The Oort cloud or Öpik–Oort cloud, named after Dutch astronomer Jan Oort, is a spherical cloud of predominantly icy planetesimals believed to surround the Sun at up to 50,000 AU. This places the cloud a quarter of the distance to Proxima Centauri, the nearest star to the Sun. The Kuiper belt and the scattered disc, the other two reservoirs of trans-Neptunian objects are less than one thousandth of the distance. The outer limit of the Oort cloud defines the cosmographical boundary of the Solar System and the region of the Sun's gravitational dominance. The Oort cloud is thought to comprise two regions: a spherical outer Oort cloud and a disc-shaped inner Oort cloud, or Hills cloud. Objects in the Oort cloud are largely composed of ices, such as water, ammonia, and methane. Astronomers conjecture that the matter composing the Oort cloud formed closer to the Sun and was scattered far into space by the gravitational effects of the giant planets early in the Solar System's evolution.

Therefore, objects on the outer fringe of the Oort cloud (i.e., around 100,000 AU)
are only weakly attracted by the Sun and may drift away into interstellar space. As
a result, the outer limit of the Oort cloud is not specifically defined. Objects that ...
