What is the Oort Cloud?
The Oort Cloud is a mysterious, spherical shell of icy objects that surrounds our solar system. It lies far beyond the orbit of Pluto and marks the edge of the Sun’s gravitational influence. Many scientists believe that the Oort Cloud contains billions, possibly trillions, of icy bodies and comets that act as cosmic leftovers from the formation of the solar system.
Voyager-1’s Epic Journey
Voyager-1, the legendary spacecraft launched in 1977, has traveled over 162 astronomical units (AU) from Earth—that’s more than 24 billion kilometers! It has already crossed into interstellar space, venturing where no human-made object has ever gone before. Yet, Voyager-1 is still nowhere near the Oort Cloud. At its current speed, experts estimate it will take the probe about 300 years to reach the inner edge of this vast cloud.
Voyager-1’s journey highlights the immense scale of our solar system and the enduring quest for scientific discovery. The spacecraft continues to send valuable data about the outer reaches of our solar neighborhood, inspiring generations to look up and wonder what lies beyond.
