Planet Jupiter

Name from the king of the ancient Roman gods.

Jupiter is the fifth planet from the Sun
Largest in the solar system – more than twice as massive as the other planets combined.
1,000 Earths could fit inside

Age : 4.6 billion years or so.
Shortest day in the solar system, taking about 9.9 hours to spin around once on its axis.

Radius : 69,911 kilometers,
Jupiter is 11 times wider than Earth.

It takes sunlight 43 minutes to travel from the Sun to Jupiter.

One day on Jupiter = 9.9 hours

Jupiter has 95 moons (Recognized by the International Astronomical Union).
The four largest moons – Io, Europa, Ganymede, and Callisto – were first observed by the astronomer Galileo Galilei in 1610 using an early version of the telescope. These four moons are known today as the Galilean satellites, and they're some of the most fascinating destinations in our solar system.
Io is the most volcanically active body in the solar system.
Ganymede is the largest moon in the solar system (even bigger than the planet Mercury).

Scientists theorized Jupiter was a mostly homogeneous mix of hydrogen and helium gases, surrounding a small, solid core of heavier elements – ice, rock, and metal formed from debris and small objects swirling around that area of the embryonic solar system 4 billion years ago.

As a gas giant, Jupiter doesn’t have a true surface. The planet is mostly swirling gases and liquids. While a spacecraft would have nowhere to land on Jupiter

Jupiter's enormous magnetic field is 16 to 54 times as powerful as that of the Earth. It rotates with the planet
