Solar System
Where the planets are today, each one's size to scale, the asteroid belt, Pluto and the Voyager probes' journey toward the Oort Cloud.
Where the planets are today
Seen from above, with the planets where they are today. Distances are squeezed to fit: Jupiter is 5 times farther from the Sun than Earth.
The planets to scale
All at the same scale. The Sun, on the left, is so big that only its edge fits: about 1.3 million Earths would fit inside it. Tap a planet to see its card.
From the Sun to the Oort Cloud
Each mark on the ruler is 10 times farther than the one before: otherwise Earth and the Oort Cloud would not fit on one screen. An AU is the astronomical unit, the Earth–Sun distance. Tap each point.
Positions calculated on your device with JPL mean orbital elements (E. M. Standish). Planet figures: NASA (Planetary Fact Sheet), rounded. Voyager: NASA/JPL.
