Facts about Jupiter
- 10
Aurorae on Jupiter produce radiation so intense that particles accelerated in its magnetosphere generate X-ray emissions detectable by space telescopes like Chandra.
- 09
Callisto, Jupiter's second-largest moon, is the most heavily cratered object in the solar system with an ancient surface dating back 4.5 billion years.
- 08
Ganymede, Jupiter's largest moon, exceeds Mercury in diameter at 5,268 kilometers and is the only moon in our solar system with its own magnetic field.
- 07
Europa, Jupiter's fourth-largest moon, harbors a subsurface ocean containing more liquid water than all of Earth's oceans combined beneath its 10-kilometer-thick icy crust.
- 06
During a single orbit around the Sun, Jupiter completes one full rotation in just 9.9 hours, making it the fastest-spinning planet in our solar system despite its massive size.
- 05
Jupiter's magnetosphere extends roughly 600,000 kilometers into space, making it the largest planetary magnetic field in our solar system.
- 04
With wind speeds exceeding 600 kilometers per hour, Jupiter's jet streams rank among the fastest atmospheric winds in our solar system.
- 03
Io, Jupiter's innermost large moon, experiences volcanic eruptions so intense that sulfur compounds reach heights of 500 kilometers above its surface.
- 02
At 11 times Earth's diameter, Jupiter's mass comprises approximately 318 Earth masses, making it the most massive planet in our solar system.
- 01
The Great Red Spot, a storm on Jupiter, has persisted for at least 350 years since its first observation in 1664 by Robert Hooke.
