The two would have been almost the same. However, over a period of a few million years ago, Venus lies much closer to the sun than our planet. It has made Venus terribly hot.Since it is closer to the sun, Venus' temperature should be a little warmer than that of the earth. As ...
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, Saturn, Uranus, and Neptune D. To explain why young stars are often surrounded by disks of gas and dust ...
MALE PROFESSOR: Last week we discussed the formation of Earth and the other rocky planets—the planets in the inner solar system.Uh, s-so, what about the gas giants?Jupiter, Saturn, Uranus, and Neptune. Well, there's two theories.But first, let's recap.We believe our solar system began...
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...

【题目】Venus金 星/ Venus is the nearest planet to Earth, and/in some ways the two planets are similar.They are both made of iron an d rock and3are about the same siz e. The pull of gravity is about the same on both planets. So if5you were standing on Venus, you would6weigh ...
Gliese 581 d and e are the planets I wanna focus on now. See, in 2009, a group of researchers made an announcement. These two exoplanets: Gliese 581 d and e do have some Earth-like qualities. Gliese 581 d had actually been discovered a couple of years earlier. And when its orbit wa...
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 ...
