How big is the Solar System, really? Even beyond Neptune and Voyager 1, an enormous part of our cosmic home still lies ahead.
In The True Scale of The Solar System, Science Time takes you from Earth and the Moon to the Sun, the giant planets, Pluto, and the distant Kuiper Belt. Discover the real distances between worlds, how long sunlight takes to reach them, and why familiar Solar System diagrams struggle to show the full picture.
Imagine flying through space at the speed of an airliner. The Moon takes days to reach. Neptune takes centuries. Farther out, the journey stretches beyond the entire history of human civilization.
Follow Voyager 1 into interstellar space, then explore the theoretical Oort Cloud—a region that may extend almost two light-years from the Sun. Finally, shrink our star to the size of a grapefruit and discover where Earth, the outer planets, and the nearest star would fit.
The Solar System is our home. How much of it have we actually explored?
