The stripes and swirls on Jupiter refer to the distinctive atmospheric features visible on the surface of the planet.
Stripes (Bands): Jupiter's prominent dark and light bands are known as "zones" and "belts". These alternating bands are created by powerful jet streams in Jupiter's atmosphere that flow in opposite directions. The lighter zones are regions where gas is rising, while the darker belts are areas where gas is sinking. These bands can change in color and intensity over time due to various atmospheric phenomena.
Swirls (Storms): Jupiter is known for its dynamic and turbulent atmosphere, which hosts a variety of storms. The most famous of these is the Great Red Spot, a massive, high-pressure storm that has been raging for centuries. Other storms and smaller vortices can form, change, and dissipate over time. Some storms, like the Great Red Spot, can be large enough to be seen from Earth with a telescope.
These features contribute to the vibrant and ever-changing appearance of Jupiter's atmosphere. They are studied extensively to better understand the complex dynamics of gas giant planets like Jupiter.
Jupiter's familiar stripes and swirls are actually cold, windy clouds of ammonia and water, floating in an atmosphere of hydrogen and helium.
The Great Red Spot: A massive, long-lasting storm on Jupiter, visible for over 350 years.
Galilean Moons: Jupiter has four large moons (Io, Europa, Ganymede, and Callisto) discovered by Galileo Galilei in 1610, each with unique characteristics. That discovery changed the way we see the universe.
Origin: Jupiter formed about 4.5 billion years ago from the same solar nebula that gave birth to the Sun and the rest of the solar system.
Discovery: Jupiter has been known since ancient times and was visible to the naked eye. It has been observed and studied for centuries.
History: Ancient civilizations, including the Babylonians and Greeks, recorded observations of Jupiter. Galileo Galilei's telescopic observations in 1610 provided crucial insights into Jupiter's moons and its banded appearance.
Orbit Eccentricity: 0.049
Orbit Length: It takes Jupiter approximately 11.9 Earth years to complete one orbit around the Sun.
Rotation: Jupiter rotates on its axis, completing one rotation roughly every 9.9 hours.
Rotation Length: A day on Jupiter is approximately 9 hours, 55 minutes, and 30 seconds.
Length of Day: A day on Jupiter is approximately 9 hours, 55 minutes, and 30 seconds.
Length of Year: 11.9years.
Escape Velocity: 59,5 km/s
Distance from Sun in AU (Astronomical Unit): 5.2AU
Spherical Specification: Jupiter is an oblate spheroid, meaning it is mostly spherical in shape but slightly flattened at the poles and bulging at the equator.
Moon/Natural Satellites: Jupiter has a vast number of natural satellites, with the four largest known as the Galilean moons: Io, Europa, Ganymede, and Callisto.
Rings: Jupiter has a faint ring system, primarily composed of dust particles.
Gravity: 2.36
Mass: Jupiter has a mass of about 318 times that of Earth.
Composition/Structure:
- Crust: Jupiter is a gas giant, so it lacks a solid surface or crust.
- Inner Core: It is believed to have a core composed of heavy elements, possibly rocky material, with a size estimated to be around 20 times the mass of Earth.
- Outer Core/Mantle: The outer core and mantle consist of dense, high-pressure gases, including hydrogen and helium.
Missions: Various missions have been sent to study Jupiter, including the Galileo spacecraft, which orbited Jupiter from 1995 to 2003. The Juno mission, launched in 2011, is currently studying Jupiter's atmosphere and magnetic field.
Temperature: Temperatures on Jupiter vary depending on depth within the atmosphere. At the cloud tops, temperatures can be as low as -145 degrees Celsius (-234 degrees Fahrenheit), while deeper within the planet, pressures and temperatures rise dramatically.
Magnetic Field: Jupiter has an extremely strong magnetic field, the strongest of any planet in our solar system.
North Pole: The north pole of Jupiter is a complex and constantly changing region, marked by cyclones and storms.
South Pole: The south pole of Jupiter is less well understood due to limited observations, but it also experiences dynamic weather patterns.
Geological Environment/Activity: Jupiter does not have a solid surface, so it lacks geological features like volcanoes, ice, or water. However, it experiences intense atmospheric activity, including storms, such as the famous Great Red Spot, a giant storm system.
Atmosphere: Jupiter's atmosphere is primarily composed of hydrogen (about 90%) and helium (about 10%), along with trace amounts of other gases.
Size: Jupiter has a diameter of approximately 139,820 kilometers (86,881 miles), making it the largest planet in our solar system.
