   May 3, 2024 · Oort cloud, immense, roughly spherical cloud of icy small bodies that are inferred to revolve around the Sun at distances typically more than 1,000 times that of the orbit of Neptune, the outermost known major planet. Named for the Dutch astronomer Jan Oort, who demonstrated its existence, the Oort.

   The Oort Cloud is a huge area of space that encompasses our solar system where long-term comets are believed to originate. An event causes them to be sent on their way towards the inner solar system, our planet Earth and the Sun. The Oort Cloud theory's creator was Jan Hendrik Oort, a Dutch astronomer ...

   What is an oort cloud?

   • The Oort cloud represents the last true remnants of the formation of the solar system. When our system formed, it contained trillions of tiny bits of rock and ice that never got to form a planet. But as the planets formed, they stirred up the debris and flung them into the outermost edges of the solar system.

   What is the origin of the Oort Cloud?

   • The Oort cloud must have been created from icy planetesimals that originally accreted in the outer part of the protoplanetary disk and were then scattered far away by the gravity of the incipient giant planets.

   How far is the Oort cloud from the Sun?

   • The Oort Cloud is a spherical layer of icy objects surrounding our Sun, a star, and likely occupies space at a distance between about 2,000 and 100,000 astronomical units (AU) from the Sun. Long-period comets (which take more than 200 years to orbit the Sun) probably come from the Oort Cloud, which is sometimes described as a “cometary reservoir."

   How far does the oort cloud extend?

   • How far the Oort cloud extends into space is not known, although Marsden’s results suggest that it is almost empty beyond 50,000 AU, which is about one-fifth of the distance to the nearest star.

   May 3, 2024 · A year earlier the Dutch astronomer Jan Oort had proposed the existence of a much-more-distant spherical reservoir of icy bodies, now called the Oort cloud, from which comets are continually replenished. This distant source adequately accounted for the origin of long-period comets—those having periods greater than 200 years.
