Wesley Fowler ASTR Chapter 11 Jupiter th Semimajor Axis is 5.2 AU (5 planet from the Sun) Orbital Period is 11.86 years Jupiter has 67 known moons Has three rings (all gas giants have rings) Synodic period is 398.9 days 4 brightest object in Earth’s sky Mean Radius: 69,900 km (~11 Earths wide) – Equatorial Radius: 71,492 km (11.21 E. Radii) – Polar Radius: 66,854 km (10.52 E. Radii) 27 Mass: 1.9 x 10 kg (318 Earth Masses) 3 Average Density: 1,300 kg/m 2 Surface Gravity: 24.8 m/s (2.53 g) Jupiter has the fastest rotation in the Solar System, making a complete rotation in 10 hours. Jupiter has a differentiated rotation, as in that it has different rotation rates at different latitudes. This is true for all gas giants Rotational Period: Equatorial: 9 hrs 50 min Polar: 9 hrs 55 min Magnetic Field: 9 hrs 55 min Jupiter has a differential radius, shaped as an Oblate Spheriod. This is caused by the planet’s very fast rotation rate. Jupiter has an atmosphere, and a magnetic field that is 20,000 times stronger than Earth’s Composition: Hydrogen (H ): 26.1% Helium (He): 13.8% Heavier Elements: 0.1% - Represents the primary composition of the entire universe, and our ancient solar nebula Jupiter’s Surface Features Banded structure of bright zones, and dark reddish belts - The zonal flow of each band is determined by eastward and westward wind Dark Belts: Eastward flow - Brownish-red - High-pressure, lower altitude Light Zones: Westward flow - Whitish - Low-pressure, high altitude Storms: Come in white ovals, red spots, and brown ovals - The Great Red Spot is a hurricane like storm, and can can fit three Earth’s inside it. Was first observed 300 years ago. Currently shrinking. - Brown Ovals are holes in the atmosphere, revealing the deepest layers of Jupiter Stratosphere: (Below the “surface”) Troposphere (Above the “surface”) - Top: Ammonia Ice Clouds [-40 km] - Mid [-60 km]: Ammonium hydrosulfide ice [maybe the red coloring agent] - Bottom [-80 km]: Water Ice (too deep to see) Jupiter has its own internal heat source leftover from its formation. - It is so hot below Jupiter’s “surface” that hydrogen exists purely as a liquid - Liquid metallic hydrogen: Hydrogen becomes an excellent conductor of electricity as it begins to liquidate and behave more like a metal. Being highly convective, the mantle creates an immensely strong dynamo effect, and thus a massive electromagnetic field. - Underneath the liquid metallic hydrogen is what is believed to be a rocky core (20,000K)
