Revealing the true nature of the gas giant planets in our Solar System is challenging. The masses of Jupiter and Saturn are about 318 and 95 Earth masses, respectively. While they mostly consist of hydrogen and helium, the total mass and distribution of the heavier elements, which reveal ...
Mars,Red Planet- a small reddish planet that is the 4th from the sun and is periodically visible to the naked eye; minerals rich in iron cover its surface and are responsible for its characteristic color; "Mars has two satellites"
Gas giants are large planets that contain more than 10 times the mass of Earth, they are also known as the Jovian or Outer Planets. Their compositions are mostly gases, such as hydrogen, and small amounts of rocky material (mostly at their cores). The four gas giants in our solar ...
Saturm土星Saturn is a gaseous planet.The other gaseous planets of the solar systemare Jupiter, Neptune and Uranus.The latter two are ice giants and are notconsidered traditional gaseous planets likeSaturn and Jupiter.Saturn's small core is made up of metallic rockand ice.Its outer layer has ...

音频定位:Last week we discussed the formation of Earth and the other rocky planets—the planets in theinnersolar system. Uh, s-so what about the gas giants: Jupiter, Saturn, Uranus, and Neptune? Well, there’s two theories, but first let’s recap. ...
such as those that revolve around it as moons. Because Neptune's large mass has captured Pluto so that the two planets remain in orbits that cross, Pluto has not cleared its own orbit and was therefore demoted from planet status to that of a newly created category,dwarf planet.Like a plan...
That process is fast enough to finish before the gas runs out. 1.What is the main purpose of the lecture? A. To describe two new theories about the formation of rocky planets. B. To discuss competing theories about the formation of gas planets. C. To compare the composition of Jupiter...
