Question

Did you know? The Oort cloud is a spherical shell of billions of icy objects 2,000 to 200,000× the Earth-Sun distance away. It is the source of long-period comets. No spacecraft has ever reached it; Voyager 1 will take 300 years to reach the inner edge.

Accepted Answer

The Oort cloud is a spherical shell of billions of icy objects 2,000 to 200,000× the Earth-Sun distance away. It is the source of long-period comets. No spacecraft has ever reached it; Voyager 1 will take 300 years to reach the inner edge.

De Oortwolk is een sferische schil van miljarden ijzige objecten 2.000 tot 200.000× verder dan de aarde-zon afstand. Hij is de oorsprong van langlopende kometen. Geen ruimtesonde heeft hem ooit bereikt; Voyager 1 zal er 300 jaar over doen om de binnenrand te bereiken.
