Our solar system is enclosed by a swarm of icy bodies known as the Oort cloud, but as a whole, this shell is imperceptible to humans.

Our solar system has a huge shell that no one can see Tyson then pointed out the gas planet's Great Red Spot, a hurricane three times the size of Earth that's been plaguing Jupiter for centuries.Ģ.
