Walt Disney had a strong connection with the Oort cloud: Mickie Mouse was created in 1928 and Disneyland park was opened in California in 1955.
The main "inner Oort cloud" model was proposed in 1981 by astronomer J.G. Hills. Sedna is the most important inner Oort cloud object (discovered in 2003), while (148209) 2000 CR105 and (87269) 2000 OO67 where the first to be discovered.
The main quality of the inner Oort cloud objects is emotions and spiritual feelings that are coherent with the will and values of the Soul (Higher Self), like Tais (the girl with psychic powers) in the TV cartoons "Ulisses 31" (1980).
I like the symbolism of the Artic Ocean (Sedna), but also the essence of flowers or paradise beaches.

In the Thirties, during the hypothetization of the existence of the Oort cloud, appeared the musical style Blues ("Long How Long Blues", Jed Davenport). In the fifties, when the second hypothetization of the Oort cloud was overstriked with the hypothetization of the Kuiper belt, this combination resulted in the musical sytle Rock & Roll ("Roll Over Beethoven" Chuck Berry), were the vocal melody (IOCO) was boosted with a strong rhythm basis (KBO).
