PLANET JUPITER - வியாழன் கிரகத்தை பற்றிய டெக்னிக்கல் தகவல்கள் !

1. Diameter: Approximately 139,820 km (86,881 miles)

2. Mass: About 1.90 × 10^27 kg (318 Earths)

3. Surface Gravity: 24.79 m/s² (2.528 g)

4. Orbital Period: 11.86 Earth years

5. Rotational Period: Approximately 9.93 hours (the fastest rotation rate of any planet in the Solar System)

6. Atmosphere: Primarily composed of hydrogen (about 90%) and helium (about 10%), with trace amounts of methane, ammonia, water vapor, and other compounds

7. Average Surface Temperature: -145 degrees Celsius (-234 degrees Fahrenheit)

8. Surface Pressure: No true surface, pressure increases with depth into the planet

9. Moons: 79 known moons, including the four largest (the Galilean moons): Io, Europa, Ganymede, and Callisto

10. Tilt of Axis: 3.13 degrees (very slight, resulting in minimal seasonal changes)

11. Orbital Speed: 13.07 km/s (47,052 km/h or 29,236 mph)

12. Surface Features: No solid surface; visible cloud tops featuring belts and zones, Great Red Spot (a massive storm system), and numerous smaller storms

13. Magnetic Field: Strong magnetic field, about 20,000 times stronger than Earth's

14. Solar Day (Jovian Day): 9.93 Earth hours (due to rapid rotation)

15. Atmospheric Density: Dense atmosphere extending deep into the planet

16. Surface Composition: No solid surface, mainly gas and liquid metallic hydrogen

17. Geological Activity: No geological activity on Jupiter itself, but significant geological activity on some of its moons (e.g., volcanic activity on Io)

18. Ring System: Faint ring system composed mainly of dust particles

19. Distance from Sun: Average of about 778.5 million km (484 million miles)

20. Albedo (Reflectivity): Average albedo of 0.52, reflecting about half of the sunlight it receives

21. Escape Velocity: 59.5 km/s (133,100 mph)

22. Weather: Extreme and dynamic weather patterns, with intense storms and high-velocity winds

23. Radiation: High levels of radiation in its magnetosphere

24. Interior Composition: Likely has a core of rock and metal, surrounded by a layer of metallic hydrogen, with molecular hydrogen and helium in the outer layers
